High-quality, high-protein soybean Yudou 25 and Zheng 92116 production technology

The contents of the national high-quality, high-protein soybean varieties Yudou 25 and Zheng 92116 were 46.3% and 48.41%, respectively, and the highest 667 square meters produced 273.3kg and 245.96kg. In the production, due to improper or no N, P and K fertilization ratio, coupled with extensive management, poor control of pests and diseases caused by protein content decreased by 2%, the output is only about 150kg. Therefore, in promoting high-quality soybean varieties, it is necessary to jointly promote high-quality, high-yield cultivation techniques, thereby stimulating the production and development of 2 million hectares of summer soybean in the Huang-Huai-Hai area, and increasing the industrialization scale and export volume. 1 Yudou 25 and Zheng 92116 Seed Production Techniques 1.1 Seed producers of seed production choose flats that have flat terrain, uniform fertility, convenient irrigation and drainage, no weight, no entrenchment, and are not susceptible to environmental impact and damage. Timely sowing, planting single plant, line length 4 ~ 6m, lined aisles, in order to identify miscellaneous, spacing 40cm, spacing 13.3cm, surrounded by a protected area. According to the typicality and uniformity, the strains were identified, and the single plants in the line were decontaminated. The hybrids were divided into different development stages such as seedling stage, flowering stage and maturation stage. Each stage was performed several times until the traits were the same. Harvested in time, mixed harvested on the selected plant line, single harvest, single transport, single off, single drying, single storage of the variety, and prevent mechanical mixing. Pay attention to disinfection and drying in the storage to keep the seed vigor. 1.2 Production of Original Species Seeds of the breeder's seeds are planted in the original nursery garden, and the ramets are identified and removed. The original species is harvested by mixing and harvesting. 1.3 The original species production in the original species garden will be the original species of fine seed production and dilute production of the original species, the original species can be a reproduction of the production of improved species, can also be directly supplied to Daejeon. 1.4 Breeding of Fine Seeds The fine seed production and fine seed production will be conducted at the seed farm or special seed base. Planted with the original species. The above three kinds of seed production are the same as the seed producers' seed production. 2 Cultivation Techniques 2.1 Rotation of the soybeans for two consecutive years or more in the summer due to rotation and appropriate ploughshares will result in reduced yields. Therefore, the plots should be selected before sowing to avoid continuous summer soybean crops. Soil moisture is good, conditions can be applied before the rake to add base fertilizer, and then sowing. If the air temperature is high before sowing, poor sensation, and large evaporation, the ploughshare will run away and delay the sowing date. 2.2 Selection of refined varieties According to the conditions, machine selection and artificial selection may be adopted to remove the grains, diseased grains, broken grains, immature grains and impurities in the bean seeds. Germination test on seeds, the germination rate should reach 85% of the national standard. If the germination rate is low, increase the sowing rate to ensure the whole seedlings. Yudou 25 and Zheng 92116 are suitable for 4~5kg per 667 square meters. 2.3 timely early sowing, seedling nursery seedlings from late May to mid-June is a suitable sowing date for summer soybeans, the earlier the sowing the higher the yield. After the wheat harvest, the soil moisture is good or the wheat harvest is after the rainfall, so it can be broadcast in time. After emergence, within 30cm of broken ridges, two plants can be left at both ends of the ridge. Broken ridges above 30cm should be transplanted with soil to make up the seedlings or reseeding the seed soaking and germination, the sooner the better. The transplant should be watered immediately after planting at 4 pm on the same day. On the basis of the whole seedlings, artificial seedlings were hand-picked. One seedling was left every 0.13m, and the density of seedlings at 667 m was 11,000 to 12,000. 2.4 When cultivating and weeding soybeans just grow true leaves (within 5 days of emergence), cultivating once, and then cultivating once or twice every 10 days, and finally ending before flowering. 2.5 Note Drainage and irrigation of soybeans before planting in case of poor drought should be accompanied by pouring water at the end of the season to ensure that all seedlings are broadcast. In the soybean seedling stage, ie within about half a month after emergence, mild drought can sprout seedlings without watering. During the flowering period of soybeans (late July to mid-August), drought should be watered, which can significantly increase soybean production. Soybean grain drought and watering, can increase 100-grain weight. Pay attention to drainage during the rainy season. 2.6 Harvesting and merging Yudou 25 and Zheng 92116 are not cracked and can be harvested after ripening. After the harvest, it is sunburned and crispy and can be used for threshing. After the seeds have been raised, they are air-dried to a moisture content of 13% or less and can be stored in storage. Soybean seeds can not be directly sun exposure, so as not to lose luster affect the commercial nature. 3 Fertilization techniques To change the traditional habits of farmers not planting soybeans or applying fertilizers blindly, according to the soil nutrient supply conditions in major soybean producing areas in Henan Province, summer soybean should be popularized with high-yielding formula fertilization techniques to increase the soybean yield to 667 square meters. 200-250kg, a typical high-yield field of about 275kg. 3.1 Before sowing seed fertilizer, 5 kg of seeds per 667 square meters shall be weighed respectively to 5 g of ammonium molybdate, 10 g of borax and 5 g of zinc sulfate, fully dissolved with 400-500 g of warm water, and then the fertilizer solution shall be sprayed on the seeds to make the fertilizer liquid full. The seeds are sown immediately after drying. 3.2 Basal fertilizer At present, the production of 667 square meters of commonly used Shiji fertilizer has the following three combinations: 1 urea 5kg, general calcium 50kg, potassium sulfate or potassium chloride 10 ~ 15kg; 2 urea 5kg, fertilizer Tiandan (soy special fertilizer) 20kg; 3 urea 2 ~ 3kg, phosphoric acid two press 15 ~ 20kg, potassium sulfate or potassium chloride 10 ~ 15kg. Optionally, it can be applied evenly when sown or sown on cultivated land. 3.3 Top-dressing basal-fertilized plots are re-applied once in 5 days of the initial flowering period of soybeans, and 5 to 7 kg of urea will be chased every 667 square meters, and 5 to 7 kg of potash will be applied as appropriate for the seedlings. The topdressing method is suitable for furrowing. For the field where base fertilizer cannot be applied, fertilizer should be applied early in the seedling stage. Generally in mid-July, according to the fertility of 667 square meters of soil urea 5 ~ 10kg, with fertilizer Tiandan 15 ~ 20kg or urea about 5kg, diammonium 10 ~ 15kg, potassium chloride 10kg or so. 3.4 Foliar spray fertilizer is sprayed with 0.03% to 0.05% ammonium molybdate solution at the seedling stage before flowering. Spraying 0.2% borax solution before flowering can increase the seed setting rate of soybean. Spraying should be performed after 4:00 pm . 3.5 Note that the amount of basal fertiliser and top dressing mentioned above is for low and medium fertility plots. For high fertility plots, basal fertiliser may not be applied with urea, and the amount of phosphorus and potassium fertilizers may be the same; 4 Plant Protection Technology 4.1 Soybean pest control seeding period Seed coating agent or carbofuran granules are used to prevent underground pests such as earthworms to ensure the whole seedlings. Seedling stage for the prevention and control of aphids, can use highly selective pesticide species, available per 667 square meters 50% anti-in Granville wettable powder 6 ~ 8g or 10% imidacloprid wettable powder 10 ~ 20g, watered 30 ~ 60kg spray Prevention and treatment not only achieves the purpose of controlling the disease but also helps to protect natural enemies. Branching and flowering period (mid-July to early August) Spraying 1% avermectin EC 2000-3000 times to prevent and control blackfly fly, and treat food pests. During the pod-graining period (mid-August to early September, 30 days before harvest), 1% avermectin EC 2000-3000 times, 50% fenthion 1000-1500 times, or 20% fenvalerin Emulsion cream 20 ~ 40ml spray control of soybean meal and soybean borer, and cure leaf insect pests. Harvesting in time, deep-turning the land to reduce the source of insects in the following year. 4.2 Prevention and control of soybean diseases Non-toxic and disease-free seeds are used before sowing, and crops are used in rotation, and seed coaters or furan granules are used to prevent underground pests such as earthworms to ensure full seedlings. At the same time, seedling stage aphids and cyst nematode diseases can be controlled and virus diseases can be controlled. happened. Branching and flowering stages are mainly used for controlling downy mildew, anthrax and purple spot. For the control of downy mildew, 35% metalaxyl WP or 80% phosphine aluminum soluble powder can be sprayed with 500-800 times solution; for control of anthrax and purple spot, etc., 1:1100 dilution of Bordeaux or 65% can be sprayed. Mancozeb WP can be 500 to 600 times liquid. After harvesting, field residues were completely removed and field pathogens were reduced in the following year. 4.3 Chemical weeding The infringement of a wide variety of weeds is a common problem. Soybeans were sown in the soil and closed to the weeds before sowing. The weeds were eliminated before and after the emergence of the soil. The commonly used agents and dosages are 50% acetochlor EC 167ml+20% tamosulfuron (chlorimuron-ethyl) wettable powder 5g+72% 2- d-butyl ester 33ml/square meter to broaden the herbicide spectrum and control efficacy.
