In order to study the production perfor‐ mance of Artemisia selengensis Turcz. Forage culti‐ vation, wild Artemisia selengensis Turcz. was used as experimental materials. The plant height, num‐ ber of plants per square meter, stem diameter, leaf length, fresh grass yield, and dry grass yield were measured in the second, third, and fourth year of growth through separate propagation and planting experiments, with a row spacing of 30 cm and a plant spacing of 30 cm. Correlation analysis, regression analysis, and principal component analysis were conducted on each trait. The results showed that: ① the average hay yield over three years was 4 633.67 kg/hm², and the hay yield in the second and third years of growth was significantly higher than that in the fourth year (P<0.05). The plant height in the second year was significantly higher than that in the fourth year (P<0.05). ② There is a significant positive correlation between plant height, stem diam‐ eter, and hay yield (P<0.05). ③ The linear regression equation between hay yield (Y) and plant height (X1) is Y=-1 184.59+77.34X1. The linear regression equation between hay yield (Y) and stem diameter (X3) is Y=-5 880.95+3 613.96X3. ④ The comprehensive ranking of the three years based on principal component analysis is the second year, the third year, and the fourth year. It indicates that the second and third years of Artemisia selengensis Turcz. are the peak periods for plant biomass accumulation, and plant height and stem diameter have a significant impact on hay biomass.

Cyperus esculentus is a kind of emerging crop with wide use and high comprehensive utilization value. Cyperus esculentus can not only be developed into food, feed, medicine and other products, but also play an important role in improving soil fertility, windproof and sand fixation, improving ecological environment and so on. Cyperus esculentus has high ecological and economic value. At present, the exploitation and utilization of Cyperus esculentus is still in the primary stage, and Cyperus esculentus industry has great development potential. This paper gave a brief overview of the origin and distribution, ecological characteristics, nutritional composition and utilization value of Cyperus esculentus, as well as the status of industrial development, to provide theoretical reference for the healthy development of Cyperus esculentus industry.

Abiotic stress is an important factor that affects the growth and development of forage. Therefore, it has a great significance to explore the characteristics, indicators, and evaluation methods of forage stress resistance for improving and stabilizing forage production. However, at present, there aren't many researches on the response and adaptive mechanism of Cyperus esculentus to stress, which directly restricts the progress of stress resistance breeding in Cyperus esculentus. In this paper, the physiological and biochemical functions and molecular regulation mechanism of common abiotic stress (drought, low-temperature and salinity, etc.) of Cyperus esculentus were briefly summarized, and the prospect of stress resistance breeding of Cyperus esculentus was put forward, in order to provide theoretical references for the study of stress resistance of Cyperus esculentus in the future.

Artemisia selengensis Turcz. is a typical rhizome plant. In order to explore the relationship between the yield of grass and various underground rhizome traits of Artemisia selengensis for feeding, the test set up four planting densities, which of 83 000, 111 000, 167 000 and 250 000 plants per hectare, respectively. The hay yield, fresh grass yield, number of rhizome buds, rhizome dry weight, spacing of rhizome node, and rhizome diameter were measured, and correlation analysis and regression analysis were carried out. The results showed that a highly significant positive correlation between rhizome diameter and hay yield (P<0.01), a significant positive correlation between rhizome node spacing and hay yield (P<0.05), a highly significant negative correlation between rhizome dry weight and hay yield (P<0.01), and a highly significant positive correlation between fresh grass yield and hay yield (P<0.01). The linear regression equation was Y=5 031.67- 5.24X2 (R²=0.693 2, F=22.60**) between rhizome dry weight (X2) and hay yield (Y); the linear regression equation was Y=1 568.76 + 523.98X4 (R²=0.711 1, F=24.61**) between rhizome diameter (X4) and hay yield (Y), which indicated that the dry weight and diameter of the rhizome of Artemisia selengensis Turcz had significant effect on overground grass yield.

Artemisia selengensis Turcz. is a typical rhizome plant. It has high feeding value, rich nutrition, good palatability, strong disease and insect resistance. In order to explore the effects of planting density on the yield and growth of Artemisia selengensis rhizome, wild Artemisia selengensis Turcz. was taken as the experimental material, adopted the method of ramet propagation. The test set up four planting densities, which of 83 000, 111 000, 167 000 and 250 000 plants per hectare, respectively. The fresh grass yield, hay yield, the number of rhizome buds, rhizome dry weight, spacing of rhizome node, rhizome diameter, and ramet biomass under different planting densities were measured. The results showed that with the increase of planting density, the spacing of rhizome nodes, the number of rhizome buds, the diameter of rhizome and the biomass of ramet decreased, the dry weight of rhizome increased. The highest fresh grass yield was found at a density of 83 000 plants per hectare, with a fresh grass yield of 13 894.70 kilogram per hectare and a dry grass yield of 4 353.33 kilogram per hectare. The planting density of 83 000 plants per hectare increased the fresh grass yield by 29.24% (P<0.05) compared to 250 000 plants per hectare, and the dry grass yield increased by 32.75% (P<0.05). The rhizome node spacing of 83 000 plants Artemisia selengensis Turcz. was 113.56% longer (P<0.05), the number of rhizome buds was more than 59.54% (P<0.05), the rhizome diameter was more than 49.26% (P<0.05), and the rhizome dry weight was less than 53.06% (P<0.05). It showed that the planting density had a significant impact on the yield and rhizome growth of forage Artemisia selengensis Turcz., with 83000 plants per hectare being the most suitable planting density.

Ryegrass is a kind of gramineous high-quality forage with wide growth environment, strong adapt⁃ ability, rich nutrition and high stress resistance. In recent years, with the rapid development of the forage industry, the optimization and adjustment of the planting and breeding structure, ryegrass as a high-quality forage in northern China has become more and more popular among farmers. Ryegrass will play a more important role in the develop⁃ ment of grassland animal husbandry. The production technology and utilization of ryegrass were briefly analyzed, in order to provide theoretical references and technical supports for field production and utilization of ryegrass.

There is a key problem in the complete set high utility pattern mining algorithms, which is that there are too many redundant high utilityitemsets . This makes it difficult for users to find useful information in a large set of high utilityitemsets, which seriously reduces the performance of high utility pattern mining algorithms . To solve this problem, it derived a concise high utility pattern mining method, which mainly included the maximal high utility pattern, the closed high utility pattern, the top-k high utility pattern, and the combination high utility pattern mining method among the three. First, this paper introduced the related problem d escriptions of concise high utility patterns. Then, from the perspectives of candidate set generation, data structure types, and pruning strategies, the paper summarized concise high utility pattern mining methods. Finally, this paper gave further research directions for concise high utility pattern, including the processing of concise high utility pattern based on negative terms, concise high utility pattern based on time and deal with dynamic and complex data .
