The invention provides a method for preventing and treating waxberry wilting disease. The method comprises the following steps: spraying a bamboo vinegar stock solution diluted by 5-10 times to soil, spraying a mixed solution of 1600-2000 times of thifluzamide and 900-1200 times of difenoconazole to tree bodies, and realizing disease prevention and treatment in cooperation with specific spraying periods, astragalus sinicus planting and nitrogen fertilizer control. Wherein the soil is sprayed for one time within 5 days after fruit picking and for one time within 2.5-3.5 cm of summer shoots, the tree body is sprayed for one time within 7 days after fruit picking and for one time within 4-6 cm of summer shoots, and the spraying period of the same batch of tree bodies is 2 days or more later than that of the soil; astragalus sinicus is sown in October, the nitrogen fertilizer application amount is controlled throughout the year, the fruit / compound fertilizer weight ratio is greater than 50, and no urea is applied. The method for preventing and treating the waxberry wilt disease only twice a week, the dosage is remarkably reduced, the immunity of tree bodies for resisting the wilt disease is further enhanced by improving the soil environment, improving the root activity, controlling the application amount of the nitrogen fertilizer and keeping the moderate tree vigor of waxberries, the prevention and treatment effect reaches 69% or above, and the method has the advantages of being environmentally friendly, efficient, easy and convenient to operate and suitable for large-scale application and popularization.

The invention belongs to the technical field of edible fungus cultivation. The invention relates to an auricularia polytricha strain, in particular to a Jiangxi auricularia polytricha strain and a breeding method thereof. The invention provides a novel Auricularia polytricha (Auricularia polytricha) strain 'Jiangxi' (Auricularia polytricha) and an efficient breeding technology system of the novel Auricularia polytricha (Auricularia polytricha) strain. The strain is stable in character and high in auricularia polytricha fruiting capacity, and systematic artificial cultivation of auricularia polytricha is achieved for the first time. According to the invention, a liquid culture medium is optimized, so that the mycelium pellet density and biomass of the strain are respectively increased by 62.65% and 55.06%, and elaeagnus pungens, pterocarya stenoptera, ligustrum lucidum ait and sophora japonica are screened as optimal matrixes through cut-log cultivation; a high-yield bag cultivation medium is developed aiming at the strain, the biological efficiency is 75-83%, and the total yield of the third-generation fresh ears is about 130g / bag. The method breaks through the bottleneck that auricularia polytricha depends on wild collection, provides germplasm and technical support for industrialization, and has good application value.

The application discloses a biological information-based genetic data mining system for Astragalus sinicus breeding, and particularly relates to the technical field of data mining; the system is characterized in that: raw sequencing data of a host genome of Astragalus sinicus and a symbiotic microorganism genome of rhizobium is collected and synchronized to generate a standardized genetic information dataset; sequence cross-contamination sites between the host genome and the symbiotic microorganism genome are identified, and genetic information interference from the microorganism is removed to obtain purified host genome data free of microorganism interference; the contribution of the microorganism genome to target traits of Astragalus sinicus is analyzed to obtain a microorganism effect weight; the purified host genome data and the microorganism effect weight are integrated to construct a trait association analysis model of Astragalus sinicus and locate trait association sites; finally, candidate breeding markers are screened based on the trait association site information to obtain a precise breeding genetic marker set; the application improves the accuracy and efficiency of Astragalus sinicus breeding.

The present application relates to the technical field of compound planting, in particular to a kind of southern winter idle field green manure optimization configuration efficient compound planting method, including step one, astragalus sinicus seed and rape seed banding sowing;Step two, astragalus sinicus seed and rape seed sowing promote growth treatment;Step three, astragalus sinicus and rape harvesting treatment;Step four, astragalus sinicus and rape crushing and turning back to field;Step five, strengthen and promote the management.Compared with prior art, a kind of southern winter idle field green manure optimization configuration efficient compound planting method is proposed in the present application, compared with traditional simple mixed sowing, in the yield of subsequent crop rice, rape straw decomposition rate, astragalus sinicus straw decomposition rate, >2mm soil aggregate formation, soil organic matter content and so on, there is greater improvement, it can be seen that the green manure optimization configuration efficient compound planting method is more conducive to soil fertilization and improve the yield of subsequent crop rice.

The invention belongs to the technical field of agricultural machinery, and particularly relates to a special huller for astragalus sinicus, in the special huller for astragalus sinicus, materials are fed into a hulling mechanism through a feeding mechanism, and astragalus sinicus seeds are rubbed and extruded in a flexible gap formed by a second flexible layer of a rolling shell and a first flexible layer of a rolling roller under the driving of the rolling shell rotating in a reciprocating mode, so that hulling is achieved; an elastic assembly used for supporting the grinding roller is arranged below the grinding roller, so that the grinding roller can float within a certain range, and the gap pressure has the self-adaptive buffering capacity. According to the invention, the first flexible layer and the second flexible layer provide soft and uniform rubbing force, so that seed damage caused by rigid impact is effectively reduced; meanwhile, the conical grinding roller is matched with the grinding shell rotating in a reciprocating mode, dynamic pressure adjustment provided by the elastic assembly is combined, seed and shell separation can be more effectively achieved, the threshing requirement is met, and therefore the problem that the threshing rate and the breakage rate are difficult to balance due to the fact that the acting force of existing universal equipment is not matched is solved.

The invention discloses a green manure turning, burying and retting method for reducing generation of weeds in a rice field and improving rice yield, which comprises the following steps: (1) interplanting astragalus sinicus in a broadcast sowing mode two weeks before rice harvesting; (2) 15-30 days before rice transplanting of the next season, the astragalus smicus in the mature period is turned and buried and returned to the field; (3) before turning and burying, uniformly spreading quicklime, and turning and burying the quicklime and the astragalus sinicus into soil together; (4) uniformly spreading calcium superphosphate after turning and burying; and (5) performing intermittent waterflooding and retting. Compared with the prior art that the astragalus smicus is turned, buried and returned to the field without retting in the full-bloom stage before rice transplanting, the turning, burying and retting method provided by the invention has the advantages that the organic matter returning amount can be effectively increased, the total nitrogen content of soil before rice transplanting is increased, the weed generation amount in the rice field is reduced, and the rice yield is increased.
