[Objective] The influence of the container soldering time on the appearance and internal quality of the finished cigarette was clarified. [Method] This paper independently developed a set of tools for measuring the tightness of strip transparent paper. With the tightness of strip transparent paper, the depression of strip transparent paper, the conventional chemical composition of tobacco, the release amount of conventional flue gas composition and the sensory quality as measuring indicators, the influences of different container soldering time on the quality of finished tobacco were compared. [Result] When the soldering iron temperature is lower than 135 ℃ and the time is less than 2 min, it has no significant influence on the dimness of the cigarette box, the tightness of the transparent paper, the chemical composition of the tobacco, the emission amount of the flue gas and the sensory quality. When the cigarette machine stops for a short time (no more than 2 minutes), it can start production normally without considering the influence of the fine container soldering iron. After the machine stops for more than 2 minutes, the strip cigarette staying on the soldering iron of the beautiful container should be taken out in time to avoid affecting the product quality. [Conclusion] The study provides a reference for the optimization of transparent paper packaging in cigarette production. [ABSTRACT FROM AUTHOR]

Accurately identifying the spatial characteristics of “non-grain” cultivated land and proposing control measures have positive significance for accurate control of “non-grain” cultivated land. Taking Youjiang District as the research area, this paper identified the spatial characteristics of “non-grain” cultivated land in Youjiang District from the aspects of land type composition, slope distribution, landscape pattern, spatial adjacency, farming distance and transportation convenience. This paper proposed optimization and control measures for different types of “ non-grain” cultivated land to in order to guide cultivated land to grow food. The results show that: The total amount of “non-grain” cultivated land in Youjiang District has reached 308. 38 km², mainly dry land, followed by garden land and forest land. The slope of “non-grain” cultivated land is mainly greater than 6°, and when the terrain slope is less than 25°, the area of “non-grain” cultivated land increases with the increase of slope grade. “Non-grain” cultivated land is fragmented, with high spatial proximity to gardens and woodlands, and strong interaction. The closer to rural settlements (less than 800 m) and roads ( less than 1 200 m), the larger the proportion of “ non-grain” cultivated land, and the spatial distribution of “non-grain”cultivated land is affected by cultivation distance and transportation convenience.

Geographical Indications (GIs) are the characteristic resource base for realizing rural revitalization, and it is particularly important to recognize the progress of research on GIs. We aimed to map domestic geographical indications research knowledge by related literature. Specifically, we obtained 921 research papers on geographical indication studies from 1994-2022 by filtering keywords through core Chinese journals, and then to explore the issuance stage, author institutions, research hotspots, and the evolution of the subject matter by means of CiteSpace V. 6. 1. R3, and then summarized the research insights by combining with literature reading. The statistical analysis of the literature showed that the research on geographical indications developed most rapidly from 2004 to 2011, the cooperative network of authors engaged in research on geographical indications was few and the scale was small, Xianning College was a high-frequency issuer, and Anhui Agricultural Science and Intellectual Property contained the most articles. The research hotspots covered 7 major clustering themes of geographical indications, agricultural products, intellectual property, trademark law, WTO, protection and rural revitalization. Geographical indications first appeared before 2000 and was the only hot topic. Since 2000, the research topics had gradually expanded into five major themes, and these research hotspots were formed between 2000 and 2004. Since 2004, there had rich subject branches but with a short development cycle. Each theme presented different evolution characteristics. Based on the analysis of cluster themes and keywords, it was found that geographical indications product connotation, geographical indications trademark protection, geographical indications and rural revitalization become the frontier hotspots in the field of geographical indications research. Geographical indications research was important to agricultural economic development and rural industrial revitalization. Domestic studies were rich in research results on intellectual property rights, protection mode, economic benefits, brand building and industrialization development of GI products. While considering the sustainable development, it was necessary to examine both the protection and development of geographical indication products from a ‘local’ perspective. Specially, it was important to integrate the strengths of geography and other multidisciplinary fields to promote the sustainable development of geographical indication products.

After the all-off society, China has entered the “post-poverty alleviation era”, and the use of digital finance is of great value to alleviating multi-dimensional poverty. This paper uses the data of CHFS2019 years to study the influence mechanism and heterogeneity of digital finance on the multidimensional poverty of farmers. Research shows that digital finance can significantly alleviate the multi-dimensional poverty of farmers, and the improvement of financial ability is an important application mechanism. Specifically, digital finance has the biggest impact on the dimension of “income capacity poverty”, while online shopping has the biggest impact on the multi-dimensional poverty of farmers. Heterogeneity analysis and quantile regression show that digital financial poverty reduction effect has “digital divide” in both space and individuals; accordingly, it is suggested to improve digital financial infrastructure and actively promote farmers to use digital financial technology, and finally strengthen financial supervision to eliminate the negative impact.

With the rapid development of digital information technology, digital agriculture has become the engine to promote the development of high-quality agriculture. Digital agriculture can not only promote the sustainable development of precision agriculture, but also improve the ability of agricultural management and decision-making. However, the popularization and application of digital technology in agriculture in our country lags behind, and the investment of digital agriculture technology is small, the talents are short, and the popularization degree of digital technology is low, the development of digital agriculture is restricted to some extent by such factors as agricultural decentralized management. Therefore, in order to promote the development of high quality agriculture, we must overcome the resistance that restricts the development of digital agriculture and activate the motive force of the development of digital agriculture. Based on the analysis of the current situation and restrictive factors of digital agriculture, this paper puts forward the theoretical logic and practical path for digital agriculture to promote the development of high-quality agriculture.

Based on the panel data of 11 provinces and cities in the Yangtze River Economic Belt from 2002 to 2021, this paper uses the SBM-GML index method and the entropy value method to measure the level of agricultural green total factor productivity and the level of new urbanization and new industrialization in the Yangtze River Economic Belt, and then uses the panel Tobit model to analyze the impact of new urbanization and new industrialization on agricultural green total factor productivity. The results show that the level of agricultural green total factor productivity of all provinces and cities in the Yangtze River Economic Belt from 2002 to 2006 is not satisfactory, but the level of agricultural green total factor productivity of all provinces and cities in the economic belt from 2007 to 2021 is significantly improved, and the level of new urbanization and industrialization in the Yangtze River Economic Belt also shows a steady upward trend. New-type urbanization and newtype industrialization have a significant positive impact on the improvement of agricultural green total factor productivity in the Yangtze River Economic Belt, and the impact of new-type industrialization is even greater. Based on this, in order to further tap the potential of new urbanization and new industrialization in the Yangtze River Economic Belt to improve the green total factor productivity of agriculture, it is suggested that all provinces and cities in the Yangtze River Economic Belt should steadily promote the development of new urbanization while continuously injecting new “vitality” into new industrialization, help improve the level of local agricultural green total factor productivity, and further reduce undesirable output by optimizing the agricultural industrial structure and transforming rural power grids.

The rural revitalization strategy is the key for China to promote sustainable economic development, coordinate regional development and ultimately achieve common prosperity in the coming period. Relying on their advantages in scientific research, education, capital, expertise, and personnel training, colleges and universities have become the core force driving the comprehensive implementation of the rural revitalization strategy. For many universities in Guangxi with tourism-related majors, although they have advantages in professional application, talent intelligence, education and training and tourism data in helping the implementation of the rural revitalization strategy, they still face problems such as inadequate policy implementation, poor coordination mechanism, limited service capacity, unreasonable research platform and team. Based on this, this paper proposes that under the guidance of the concept of symbiosis and integration, measures such as establishing the service concept of systematic symbiosis, building the discipline system of co-construction and sharing, expanding the service field of co-development and resonance, strengthening the service talents of symbiosis and win-win can provide a strong guarantee for the implementation of the rural revitalization strategy of tourism colleges in the area.

Based on remote sensing image data and statistical data, this paper analyzed the characteristics, driving factors, impact effects and future trends of land use change from 2019 to 2021 by using land use type transfer model, Markov model, ecological footprint model and grey correlation analysis, so as to provide reference for the sustainable development of Jingzhou City in Hubei Province. The results show that: ① The significant changes of land use are construction land and bare land in Jingzhou City, which reflects the improvement of the city’s urbanization level;the main characteristics of land use change are the decrease of cultivated land, wetland and water area, while the increase of forest land and grassland reflects the improvement of the ecological level of the city. ②The main driving factors of land use change in Jingzhou are population growth, economic development, urbanization process and policy system. These factors promote the expansion of construction land by affecting the demand and supply of land use, inhibit the maintenance of cultivated land, wetland and water area, contribute to the improvement of bare land, and support the increase of woodland and grassland. Scientific and technological progress is also an important driver, which improves bare land cover by increasing the efficiency and quality of land use, promoting vegetation restoration and ecological construction. ③Land use change in Jingzhou City has a negative impact on the ecological environment. On the one hand, land use change leads to the reduction of important resources such as arable land, wetlands and waters, reducing the productivity and stability of ecosystems. On the other hand, land use change leads to the increase of energy-intensive resources such as construction land, which increases the load and pressure on the ecosystem. These influences lead to the increase of ecological footprint and the decrease of ecological carrying capacity, the expansion of ecological deficit and the intensification of ecological imbalance in Jingzhou City. ④Land use change in Jingzhou City has both positive and negative impacts on social economy. On the one hand, land use change promotes the increase of construction land, improves the level of economic development and the living standards of urban residents, and enhances the function and competitiveness of cities. On the other hand, land use change inhibits the maintenance of cultivated land, wetlands and water areas, reduces the level of agricultural development and the living standards of rural residents, and weakens the foundation and backing of agriculture. These influences indicate that there is a problem of unbalanced urban and rural development in Jingzhou City during the study period, and it is necessary to coordinate the relationship and interests between urban and rural areas.

The grassland area is nearly 400 million hm 2 in China, accounting for more than 40% of the land area. Grassland plays an important role in animal husbandry and environmental protection. Although China has taken many measures to curb grassland degradation, grassland degradation is still widely spreading due to overgrazing, abuse of arable land, climate change and other factors. In this paper, the present situation of grassland degradation in China was analyzed in detail. At the same time, the grassland degradation mechanism, the grassland ecosystem function, the grassland degradation diagnosis methods, the grassland restoration and improvement, the utilization of geospatial technology and the grassland management methods were discussed in depth. What’s more, the roots of grassland degradation, the characteristics of grassland degradation, and the control strategies of grassland degradation were analyzed deeply based on the basic situation of grassland degradation in China. The research results not only provide theoretical support for the restoration of grassland ecosystem, but also guide the improvement and restoration of degraded grassland and promote the sustainable development of the grassland ecological animal husbandry in China.

Under the background of the “double carbon” strategy, in order to achieve green and low-carbon development of the city, it is necessary to scientific disposal and utilize garden waste, to achieve its reduction, harmlessness and resourcefulness, to “turn waste into treasure”, and to alleviate the pressure of urban organic solid waste disposal. This paper summarizes and discusses the research progress of greening resource utilization such as mulching, composting, nutrient conversion, materialization, solid fuel conversion, bio-gasification, pyrolysis multi-coupling and landscaping, and provides an outlook on the future development trend. It is expected to provide reference for accelerating the realization of green and low-carbon resource utilization of garden waste. [ABSTRACT FROM AUTHOR]

The decrease of urban population density has become one of the important factors restricting the development of some cities and towns. Taking Hunan Province as a case, this paper explores the relationship between urban population density and land use diversity based on the geographical weighted regression model, and the Pressure-State-Response model was constructed to explore the impact path of urban land use diversity on population density in Hunan Province. The results showed that: There is an obvious spatial correlation between urban popu- lation density and land use diversity of urban construction land in Southern Province, but the aggregation trend is opposite. 2 Simplified way if urban construction land use is not conducive to the diversity of the urban land use of Hunan Province, is unfavorable to the promotion of urban population density of Hunan Province, the industrial layout can guide the promotion of Hunan Province, focus on economic development, im- prove the urban public service capacity is improve the urban land use diversity, in turn, the effective method to improve the density of urban population. 3 There is a weak negative correlation between the added value of secondary and tertiary industries and urban population density in Hunan Province, and the pattern is "high in the south and low in the north". The correlation between disposable income of urban residents and urban population density in Hunan Province shows a pattern of "high in the northwest and low in the southeast", and there is a boundary between positive and negative correlation in the central urban area of Changsha. Finally, some policy suggestions are put forward from the as- pects of optimizing the urban function system to deal with the problems left over from history and promote the orderly increase of population density.

This paper focuses on the analysis of the relationship between rural revitalization and high-quality development of agriculture and animal husbandry, expounds the key significance of promoting high-quality development of agriculture and animal husbandry in Inner Mongolia under the strategy of rural revitalization, and puts forward specific strategies to provide reference for relevant research [ABSTRACT FROM AUTHOR]

The development of e-commerce has brought a wide and profound impact on agricultural production and business activities, and has become an important driving force to promote farmers’ entrepreneurship and rural economic development. This paper empirically examines the impact of the level of e-commerce development on farmers’ entrepreneurship based on the panel data of 31 provinces (cities) in China from 2013 to 2021 and analyses the regional differences. The findings show that the level of e-commerce development has a significant promotion effect on farmers’ entrepreneurship, which means that with the development of e-commerce, farmers are more likely to participate in entrepreneurial activities. However, this impact is highly variable across regions. Compared to the central and western regions, the development of e-commerce has a greater role in enhancing farmers’ entrepreneurship in the eastern region. Further mechanism analyses show that there is a significant mediating effect of industrial structure upgrading in the impact of e-commerce development on farmers’ entrepreneurship.

The education gap is one of the most important factors influencing the urban-rural income gap in China, while higher education is an important way to cultivate excellent human resources, and the investment of educational resources plays a significant role in improving farmers' literacy and labour skills, and effectively improves their labour productivity, promotes farmers' income and employment, and thus reduces the urban-rural per capita income gap. This paper uses provincial panel data of 31 provinces (cities) in China from 2008 to 2020 to explore the impact of rural human capital on the urban-rural income gap using the ordinary least squares (OLS) method, and uses the mediation effect model to test whether rural human capital inputs are effective in narrowing the urban-rural income gap under the influence of improved food security. The study shows that: ① Rural human capital inputs play a significant role in reducing the urban-rural income gap, with the largest effect in the central region, while the effect is weaker in the east and west compared to the central region. ② Food production plays a positive mediating role in the effect of rural human capital and the urban-rural income gap, which is most obvious in the central region. Accordingly, corresponding policy recommendations are put forward in the hope of providing reference for promoting progress in the level of agricultural development, revitalisation of rural areas, and effective improvement of farmers' income, and ultimately promoting the rapid, balanced and sustainable development of China's economy.

[Objective] The effects of optimizing fertilization on yield and economic benefit of winter potato under chemical fertilizer reduction were discussed in this paper. This study explored the reasonable and scientific fertilization amount in southern potato winter cropping district, and provided theoretical basis for the green and efficient development of winter potato industry in Guangdong Province. [Method] There were three treatments, including optimizing fertilizer, conventional fertilizer and no fertilizer treatment. The effects of three treatments on yield, nutrient content, quality and economic benefit of winter potato in Guangdong Province were studied with Favorlta first level virus-free seed potato as experimental material. [Result] The optimizing fertilizer treatment has higher total yield, marketable tuber yield and total value and lower fertilizer cost than the other two treatments. The total yield and marketable tuber yield of optimizing fertilizer treatment were 1 093.8 kg/hm² and 793.4 kg/hm² higher than conventional fertilizer treatment. There was no significant difference between optimizing fertilizer treatment and conventional fertilizer treatment on potato tuber quality parameters (P>0.05). The comprehensive partial productivity of nitrogen, phosphorus, and potassium fertilizers of optimizing fertilizer treatment was 33.52 kg/kg, increased by 24.55%, significantly higher than conventional fertilizer treatment. The fertilizer cost of optimizing fertilizer treatment was 3 334.2 yuan/hm² lower than conventional fertilizer treatment, decreased by 19.92%. The total value of optimizing fertilizer treatment was 36 446.0 yuan/hm², significantly higher than conventional fertilizer treatment. [Conclusion] Overall, optimizing fertilizer treatment was a better choice with a good yield, quality and value of winter potato in Guangdong Province. The optimizing fertilizer could reduce chemical fertilizer in winter potato cultivation, achieve green and efficient while ensure the improvement and stability of yield and quality.

This paper analyzes the overall characteristics and regional differences of land use efficiency and landscape pattern in all districts and counties of Guangxi in 2020 under the research framework of ESDA-GWR, and quantitatively studies the impact mechanism of patch shape characteristics and spatial distribution characteristics of cultivated land, rural residential land, and urban construction land on land use efficiency. The results show that land use efficiency of Guangxi is generally on a moderate level yet with significant regional differences, the efficiency of center areas within Prefecture level are generally higher relative to the surrounding areas. The Beibu Gulf Economic Zone shows a strong strength on socio-economic development with a high land use efficiency, while the Xijiang Economic Belt develops fast but with a low land use efficiency. Landscape metrics of different areas in Guangxi share a significant positive spatial correlation. The north and southwest part of Guangxi use their land resources in a more intensive way, while central and southeast part is in an extensive developing mode. Regular and contiguous arable land, economical and intensive rural residential land, and "One-Core-Multipart" urban construction land can significantly improve land use efficiency. Among them, the layout of urban construction land that reaches a larger scale and has a clear central urban area has a particularly significant positive impact on land use efficiency.

From the point of view of ecosystem energy and elemental balance, eco-chemometrics reveals the biogeochemical cycle of elements and the mechanism by which ecosystems regulate environmental change. This paper summarizes the recent achievements in ecological chemistry measurement of plants, litter, soil and soil microorganisms C, N, P and their response to environmental change in Xizang, and puts forward the future research direction. The results show that the plant-litter-soil-microbe system C, N and P in plant litter has a strong correlation and is significantly influenced by biological factors, abiotic factors and human activities. Plant growth is mainly restricted by N element, N content is higher when C and P are in extreme decline, and plants show strong competitiveness and high internal stability through self-regulating ability. Soil nutrients show a certain “surface aggregation” effect. Under the influence of altitude and temperature, microbial decomposition rate of litter decreases, which may explain the poor soil fertility in high elevation areas. The research on ecological stoichiometry of plant litter soil microbial system can be conducted in long-term, multi factor interactive control experiments at multiple scales and different ecosystems in the future.

The vision orgon is a very important sensory organ for fish. Fish eyes can not only sense light sensitivity and color, but also perceive the shape, size, and movement of objects. The visual function of fish has a close connection and important role in feeding, clustering, reproduction, defense and other behavioral aspects. To study the progress of color vision ability in fish, this paper investigates the development and status of different research methods on color vision ability in fish using the current major international databases（Science Direct, JSTOR, Wiley Online Library, SpringerLink, ProQuest, etc.） as data sources and uses bibliometric analysis to study the development and current status of different research methods on fish color vision ability. This study was conducted to understand the visual characteristics of fish in a more in-depth way, which can provide a reference for future methods such as changing the color of lights in fishing vessels to improve the effect of fish attraction, controlling the color and light intensity of the breeding environment to improve the breeding efficiency in the process of factory farming, and controlling the help of fish migration to protect migratory fish species.

Phosphorus is one of the essential nutrients for crop growth and development, and plays an important role in the life process of crops. Crops have formed a series of low phosphorus adaptation mechanisms in the long-term evolution process, mainly involving the activation, absorption, transport of soil phosphorus and the recycling and reuse of phosphorus in crop tissues. In this paper, the latest research progress on the mechanism of low phosphorus tolerance of crops was reviewed from four aspects: root morphology, root exudates, symbiotic system with microorganisms, and molecular mechanism under low phosphorus stress, in order to provide reference for crop cultivation regulation and improvement and breeding of low phosphorus tolerant crop varieties.

As one of the main courses for the cultivation of professional quality and skills of horticulture specialty, the exploration on the mixed teaching reform of fruit cultivation course is still very limited. At the same time, the teaching pattern and teaching system of “curriculum ideological and political education” of the curriculum are not perfect, and the educational function of the curriculum is not fully played, which restricts the training of new farmers. In this paper, the implementation of new concepts, new missions, new goals and new measures of “Anji consensus”, “Beicang Action” and “Beijing Guide”was taken as the core, the moral education was regarded as the fundamental,strengthening agriculture and the development of rural areas were taken as their own responsibility. From the construction of teaching resources in the “earth classroom”,the exploration of blended teaching mode, the construction of interactive teaching design, the renewal of the “four modernizations” of teaching contents by scientific research, the exploration of diversified teaching methods based on the student-centered, diversified course evaluation integrated with knowledge, ability and process, the reform and practice were carried out. The teaching results of innovation and practice of TCE and TSFP teaching mode of fruit tree cultivation course under the background of new agricultural science were condensed and formed. The constructed TCE and TSFP mixed teaching model was highly operational, replicable and it could be applied in the mixed teaching of plant production courses, which was of great significance for improving the training quality of new agricultural and forestry talents, and promoting agricultural modernization and rural revitalization in this region.
