High-yield Cultivation Techniques for High-yield, Soybean Varieties

1. Select land for planting land for pollution-free, high-oil special soybeans, and there should be no serious pollution sources within 5km. The environmental conditions for soybean growth must meet the pollution-free, high-oil soybean quality standards. 1, 1 rational rotation of pollution-free high-yield soybeans should be properly selected and arranged gargle, we must adhere to a reasonable rotation, to avoid smashing, to eliminate heavy smashing. Wheat, wheat, soybeans, corn, soybeans, wheat, soybeans, corn, grains, wheat, and other rotations should be adopted according to local conditions. 1-2 Fine soil preparation In soil cultivation, we must adhere to the soil cultivation system that combines loose, tumbling, and rotation with deep soil as the main body, and vigorously promote the deep soil cultivation method. Planting pollution-free high-oil soybean plots should be all-round deep, and use all-round deep-sinking machines for deep loosening and deep depths of 40-50cm. The land that was formerly occupied by wheat stubble was to be turned upside down, and the ground was full of fine grasses in autumn or spring. The corn stalks, sorghum pods, and glutinous rice should be turned autumn and autumn, and the autumn stalks should be smashed to reach the sowing state. Ridge cultivation of soybeans requires autumn ridges or priming of ridges in early spring to keep the lyrics. The depth of the ground is generally 20-22cm; the depth of the ground is 10-16cm. Suitable tillage time should be based on soil moisture and soil quality. 2, selection and treatment 2, 1 selection of varieties according to the different temperature zone with a suitable selection of high-oil soybean varieties. The first accumulated temperature zone: Nongken 4 and Nongken 5; the second accumulated temperature zone: Hongfeng 9 and Nongken 18; the third accumulated temperature zone: Hefeng No. 40 and Hongfeng No. 8; the fourth accumulated temperature zone: Yanjiandou No. 3; Fifth accumulated temperature zone: Dongnong 44; Sixth accumulated temperature zone: Dongnong 45. 2、2 Seed treatment Seeds must be manually selected or selected seeder before seed sowing in 2 or 2 or 2 seed selection, remove diseased spot grain, broken half grain, impurity, etc., the purity is higher than 98%, and the degree of clarity is above 97% The moisture content is less than 13%, and the germination rate is above 95%. 2,2,2 micro fertilizer dressing Seed dressing of ammonium molybdate: Dissolve ammonium molybdate with a small amount of warm water and add water to make a 5% solution of ammonium molybdate. Stir with spraying while using liquid for 1% of the seed amount. , Note that the iron process is not available during the seed dressing process and do not dry the seeds after the seed dressing so as to avoid seed coat rupture and affect the seed germination rate. 3, scientific fertilization to implement soil testing and formulating fertilization, pay attention to straw crushed field or abdomen field, so that manure and fertilizer, microbial fertilizer application, organic nitrogen fertilizer and inorganic nitrogen fertilizer is not more than 1:1. Apply 15t/h of farmyard fertilizer as base fertilizer; 150kg/h of diammonium phosphate, 50kg/h of urea as seed fertilizer, 10kg/h of urea at flowering stage of soybean, and 1.5kg/h of potassium dihydrogen phosphate. 500kg water spray. 4, timely sowing date, 4 sowing method Soybean "ridge three" cultivation method is the combination of soybean fine sowing and deep loose, deep combination of high-yield soybean cultivation techniques. Two rows of equidistant precision sowing on mechanical ridges are used. The distance between the two rows is 10-12?, the distance between the points is 18--20?, and 3-4 per hole. 4, 2 reasonable close planting in accordance with the fertilizer should be thin, thin should be dense; late-maturing varieties should be thin, early-maturing varieties should be dense; wide spacing should be thin, narrow row spacing should be the principle of flexible control. 4, 3 sowing quality The local table 5? The depth of daily average ground temperature reached 7-8c began to sow. Operating standards: Non-acupuncture sowing seeds within 20? is broken, with no more than one broken bar at every 5?. Cover the earth evenly and suppress it in time. 5, to strengthen field management 5, 1 deep loose and cultivator weeding in the artificial or mechanical weeding, it is best to carry out deep furrows, depth 20--25? For those who do not have deep loose conditions, using a shovel plowing a plow practice. The first pass was performed after the pea sprouts were flushed out. The second pass was performed at a soybean height of 10 , and the third pass was conducted at the initial flowering stage of soybeans. In the soybean seedling stage, flowering period and mature stage, three times of removing impurities, removing the mixed strains and the abnormal strains, and pulling the grasses before the formation of grass seeds in early August. 5, 2 chemical regulation When the field growth is too prosperous have lodging risk, Fengshui Po and other chemical control agents should be sprayed, in the initial flowering period or full flowering period by 1h with control agent type soybean harvest 15 generations plus appropriate amount of water spraying Can protect the flower, prevent lodging, improve quality, increase production significantly. 6. Comprehensive prevention and control of diseases and pests (1) Selection of high-yielding, high-yielding, disease-resistant insect-resistant varieties. (2) Use reasonable rotation, deep turning, and cultivating and weeding to improve the soil and field environment and create unfavorable living conditions for pathogens, eggs, etc. to achieve control effects. (3) Physical control method: When field pests reach the control index, light trapping is used for physical control. (4) Biological control methods: release of ladybugs to prevent soybean aphids, or release of Trichogramma, use of Beauveria bassiana to control soybean borer.
