Conservation tillage is an important way to ensure the sustainable utilization of cultivated land and a key measure to speed up the implementation of a food crop production strategy based on farmland management and technological application. Its economic effects have attracted more and more attention from all walks of life. Based on the micro-survey data from 2 127 grain growers in the main grain-producing areas, this paper applied the stochastic frontier production model to estimate the grain production efficiency of adopters and non-adopters. The Tobit model and propensity score matching method were implemented to examine the impact of the adoption of conservation tillage technology on grain production and environmental efficiency. The main results showed that: (J) The adoption of conservation tillage technology had the effect of ' increasing efficiency and reducing emissions' in grain production, and the conclusion was still valid after alleviating possible endogenous problems and a series of robustness tests. © In terms of scale, small-scale farmers adopted conservation tillage technology 'only to increase efficiency, not to reduce emissions,' medium-scale farmers adopted the technology ' only to reduce emissions, not to increase efficiency,' and large-scale farmers adopted the technology ' to increase efficiency and reduce emissions.' © In terms of production efficiency, the adoption of conservation tillage technology by farmers with high production efficiency ' not only increased efficiency but also reduced emissions.' The effects of ' increasing efficiency' and ' reducing emissions' adopted by farmers with medium or lower production efficiency were not verified. ® In terms of technology combination, adopting conservation tillage technology in combination focused on improving efficiency. The adoption of the combination of ' straw returning to field+subsoiling,' ' straw returning to field+no-tillage direct seeding,' and ' subsoiling+no-tillage direct seeding+straw returning to field ' significantly improved grain production efficiency but did not play its due positive role in environmental efficiency compared to non-adopters. Based on the conclusion of the empirical research, we should attach great importance to the popular application of conservation tillage technology and guide and support farmers to actively and consciously adopt this technology. On the other hand, it is necessary to combine the resource endowment and actual production demand of different types of farmers and selectively formulate the popularization scheme of conservation tillage technology.

Objective This paper aims to assess the indirect influence of virtual water flow on metropolitan-scale agricultural water stress in Sichuan province. It investigates the spatiotemporal variation in this context, elucidating how persistent growth in agricultural water use and the movement of virtual water through agricultural products across the province indirectly impacts regional water stress. Method The AquaCrop model was employed to calculate the water footprint of 16 different crops from 2000 to 2018 in all metropolitan cities within the province. The calculation of inter-province virtual water flow was based on annual balance between crop production and food demand, by considering the minimum transportation costs cross the province. These calculated results were then used to analyze the influence of virtual water flow on agricultural water stress. Result From 2000 to 2018, the average water footprint of crop production in Sichuan was estimated to be 28.4 billion cubic meters per year. The total water footprint of crop production in the province exhibited a fluctuation during the studied period, with the most notable change observed in Leshan. The province experienced a net increase in virtual water inflow, with the Western areas receiving more inflow than the Eastern regions. The continuous influx of virtual water has contributed to the alleviation of agricultural water stress in the province, reducing the number of cities experiencing increased water stress due to virtual water outflows from four in 2000 to one in 2018. Conclusion The analysis of physical and virtual water highlights the need for Sichuan province to enhance the regulation and optimization of virtual water trade as a means to mitigate agricultural water stress.

With the active promotion of the concept of common prosperity, farmland has once again become the focus of attention in political and academic circles, and many scholars have advocated the further visualization of the property value of farmland elements to increase farmers' income. To promote the coordinated development of China's food security and common prosperity strategies, this paper attempts to reveal the dilemma facing farmland capitalization. Theoretically, based on the factor allocation decision logic of full-time and part-time farmers, this paper proposed the dilemma of farmland capitalization between increasing food production and farm household income. We empirically constructed a model to measure farmland capitalization and characterized its degree in 27 provinces in China's mainland from 2004 to 2020. The study also provided empirical support for the theoretical analysis by using a threshold regression model and a mediating effect model based on 790 microsamples from typical provinces. The results found that: ① Farmland capitalization showed a trend of increasing year by year nationwide, with a spatial distribution pattern of spreading from the center to the surrounding areas, and the provinces with a higher degree of farmland capitalization were concentrated in the main grain-producing areas. ② The impact of farmland transfer prices on grain production had structural effects depending on the degree of farmland capitalization: In the moderate capitalization scenario (farmland capitalization≤1.011), farmland price increases promoted the expansion of food crop acreage; in the excessive capitalization scenario (farmland capitalization≥1.154), farmland price increases suppressed food crop acreage. ③ Farmland capitalization helped to meet farmers' psychological expectations on the value of farmland assets, and significantly increased farmers' income by promoting two paths: the outflow of farmland and off-farm employment. ④ Farmland capitalization in China was facing a dilemma between increasing food production and increasing farmers' income, which posed an important potential problem for national food security. The capitalization of farmland can not only improve the problem of insufficient property income in the income structure of farm households, but also promote the non-farm transfer of rural labor, but behind it is the fact that a large amount of farmland is 'nongrain.' In the future, the Chinese government should emphasize the production factor attributes of farmland, use policy tools to guide the rational return of farmland prices, improve the market for productive agricultural services, and prevent the risk of farmland over-capitalization.

Carbon emission from crop production is one of the important sources of greenhouse gas emission in China, and it is a hot issue on agricultural ecological environment in recent years. Based on the statistical data of agricultural production input, crop yield, cultivated land area and crop sowing area in Hebei province from 2010 to 2018, this paper studied the dynamic changes of carbon emission of crop production inputs, and analyzed the proportion of carbon emission for each different crop production inputs, so as to provide a theoretical basis for energy conservation and emission reduction in agricultural production, and in the end to realize the low-carbon agriculture. The results showed that from 2010 to 2018, the carbon emission from crop production in Hebei province took 2015 as the turning point, showing a trend of increasing first and then decreasing. From 2010 to 2018, the total carbon emissions from crop production, carbon emissions per unit yield and carbon emissions per unit cultivated land area in Hebei province were 22.19-104-26.74x104tCO2 eq, 0.21-0.30tCO2eq·t-1 and 3.40-4.10tCO2eq·ha-1, respectively. The total carbon emission of crop production, carbon emission per unit yield and carbon emission per unit cultivated land area in 2018 were the lowest, decreasing by 17.0%, 30.0% and 17.0% respectively compared with the highest value. The 9-year average carbon emission of chemical fertilizer, pesticide, agricultural film, diesel fuel and irrigation electricity accounted for 38.6%, 2.1%, 11.5%, 34.7% and 13.1%, respectively. Chemical fertilizer and diesel fuel were the main sources of agricultural carbon emission, accounting for more than 30%. The dynamic change of carbon emission of crop production inputs was obviously affected by the national policies. It is suggested that the carbon emissions from agricultural production should be guided by national policies, and measures such as formulating mature agricultural management system, strengthening agricultural technology training and promoting the application of advanced cultivation techniques should be taken to reduce the carbon emissions from agricultural sources, so as to promote the green development of agriculture.

Objective Agricultural production in most regions in northern China relies on irrigation. Understanding spatiotemporal variation of the demand of different crops for water is critical to improving agricultural management. Taking the northwest Shandong province as an example, this paper studies the change in its demand for irrigation. Method We took winter wheat as the model plant, and calculated its water demand based on the Penman-Monteith formula. Spatiotemporal variation in the water demand was analyzed using the Mann-Kendall mutation test, the inverse distance weighting and the interpolation method. The factors that affect the water demand was calculated using the Pearson correlation analysis method. Result Annual average irrigation water demand of the winter wheat is 339 mm, but has been increasing. Spatially, distribution of irrigation water demand is ring-shaped across the studied region, with the shape of the rings varying with growth season. The relative humidity and sunshine duration are the factors that affect the irrigation water most, with the former negatively correlated while the latter positively correlated with the irrigation water demand, both at significant level. Conclusion The irrigation water demand of winter wheat in northwest Shandong province has been increasing. Spatially, it increases from the northeast to the southwest. Precipitation cannot meet the demand of the wheat during its seeding, returning green and elongation stages. Topping up the soil water by irrigation is hence required. [ABSTRACT FROM AUTHOR]

Objective: Optimizing irrigation is critical to sustaining agricultural production in arid and semi-arid regions. The purpose of this paper is to investigate the feasibility of using pan-measured evaporation (Ep) to optimize irrigation for greenhouse lettuce production. Method: The experiment was conducted using weighing-lysimeters installed in a greenhouse. We compared five treatments by irrigating the crop at 30% (I1), 50%, (I2), 70% (I3), 90% (I4) and 110% (I5) of Ep measured from a standard evaporation pan with diameter of 20 cm, respectively. In each treatment, we measured the evapotranspiration, above-ground biomass, yield and water use efficiency, from which we calculated the optimal irrigation amount and its associated pan coefficient (Kp). We rotated the lettuce after harvesting the first one. Result: It was found that Ep increased as time elapsed, and the cumulative Ep of the rotated crop was 96.0 mm, increasing 33.4% compared to the first harvest. Solar radiation affected Ep most at significant level (P<0.01). The cumulative evapotranspiration in the first and second harvests varied from 43.4 mm to 70.4 mm, and 58.3 to 73.6 mm, respectively, both increasing with the irrigation amount. The cumulative pan-evaporation in the rotated crop under I1, I2 and I5 was 58.3 mm, 67.0 mm and 73.6 mm, respectively. With the increase in irrigation amount, the aboveground biomass increased firstly followed by a falling. Compared with I1 and I5, I3 increased the aboveground biomass by 17.5%-38.2% (P<0.05) and 4.2%-13.2% (P<0.05), respectively. Optimizing the irrigation significantly improved the yield and water use efficiency. Compared with I1 and I5, I3 increased the yield by 36.6%-37.3% (P<0.05) and 6.1%-23.7% (P<0.05), water use efficiency by 9.9%-15.2% (P<0.05) and 12.6%-61.4% (P<0.05), respectively. There was a quadratic relationship between the yield and the pan irrigation coefficient (Kp=0.77) with P<0.01. Conclusion: Among all treatments we compared, irrigating 70% of evaporation measured from the 20 cm standard pan was optimal for greenhouse lettuce production with a pan irrigation coefficient of 0.77.

Whether farmland transfer can produce farmers’ income growth is an issue that has been widely concerned by society. However, previous empirical studies are quite different. This paper believes that the neglect of the heterogeneity of the impact of farmland transfer has led to these different conclusions. Thus, using the China Family Panel Survey (CFPS) data during 2010-2018, this paper analyzed the impact of farmland transfer on different types of farmers and different sources of income. The basic empirical results showed that: Firstly, farmland transfer did increase the income of farmers, but it was mainly on transfer‑out farmers, and the impact on the net income of transfer ‑in farmers was not obvious. Secondly, the impact of farmland transfer on different sources of income of the transfer‑in farmers and transfer‑out farmers was inconsistent. The growth rate of wage income of transfer‑out households was much higher than the decline rate in operating income. And wage income contributed 80% of the growth in net income of transfer‑out households; as for transfer ‑in households, the growth in operating income could not compensate for the decline in wage income, which eventually could not increase their total income obviously. The above empirical results did not change after a series of model sensitivity analyses such as the difference‑in‑differences model and the treatment effect model, indicating that the basic conclusions were robust. Furthermore, we analyzed the reasons for income heterogeneity and found that the key mechanism was on the labor resource allocation decision. Actually, for transfer‑out households, farmland transfer could increase the probability of migrant work and business opportunities, as well as the labor input for non‑agricultural production. On the other hand, for transfer‑in households, they would invest more labor in agricultural production and increase agricultural inputs. Further policy discussions also found that due to the weak dependence of transfer‑out farmers on technological improvement, the transfer‑out farmers only needed to ensure that they could find alternative jobs to obtain a higher income; but for the transfer ‑in farmers, due to lack of sufficient technical assistance, their land production improvement was limited. Thus, it was difficult to produce the optimization of resource allocation mentioned in the theory of land retention, which might limit the further expansion of the farmland transfer market. In summary, the research in this paper provides certain theoretical and empirical evidence for optimizing the land transfer policy, increasing the participation rate of land transfer, and finally realizing the improvement of the social welfare of farmers.

As one of the most important staple crops in China,wheat production target both high yield and high quality is very essential to simultaneously meeting the demands for food security and life quality. It has been found that both contents of key chemicals and processing quality vary greatly within different layers of wheat kernels. This provides a potential approach to achieve both high-yield and high-quality of wheat. In this paper,we detailly reviewed the spatial distributions of protein and its components,starch,dietary fiber and microelements. We further discussed the underlying mechanisms on the formation of protein and starch spatial distribution in the views of supply of substrate and synthetic capacity of protein and starch. The paper also summarized the regulation effects of cultivation practices on quality spatial distribution. Finally,we proposed the breakthrough solutions for exploring the underlying mechanisms on quality spatial distribution. This paper will provide research views for achieving the production of wheat with both high yield and high quality. [ABSTRACT FROM AUTHOR]
