1. Establish a base. The following points should be noted in the establishment of low-yield soybean bases: 1 There are no sources of pollution around the base, including environmental pollution and wind pollution from pesticides in neighboring plots; 2 The base must have sufficient water sources with good water quality, and the irrigation and drainage is convenient; 3 The soil is fertile and there are no pesticide residues. ;4 The transportation is convenient to ensure that the soybeans can be transported to the factory for processing in time after harvest. 2, timely sowing. In order to give full play to the advantages of various varieties and ensure the yield and quality of green soybeans, timely sowing according to climatic conditions. At present, soybeans suitable for planting in our city include 8901, Taiwan 75 and Zhejiang Fresh Bean No.1. Spring soybeans and autumn soybeans can be sown according to market dynamics. 3, fertilizer and water management. Soybeans have different water requirements for each growth period. Sew ditch water should be poured after sowing to promote seed germination. Seedling stage to properly control the water, promote deep roots, enhance the ability to resist lodging late. After flowering and podling, there is an increase in the demand for water, and a balanced water supply must be maintained during this period. Soybean root rhizobia can fix nitrogen, so there is less demand for nitrogen fertilizer, and appropriate application of phosphorus and potassium fertilizer. Fertilizer single-season fertilizer arrangements are as follows: 1 heavy base fertilizer, mainly organic fertilizer, applied 500-1000 kg of organic fertilizer per acre. 2 After the seedlings are unearthed, topdressing water and fertilizer 2-3 times, in particular, the growth period of the young soybeans in autumn is short, timely dressing, to ensure that the pre-flowering cofferdams are sealed, each application of superphosphate 10 kg, ammonium bicarbonate 5 kg. 3 before the application of flower fertilizer, soybean flowering period of vegetative growth and reproductive growth at the same time, the largest demand for nutrients, at this time, 20-25 kg of compound fertilizer per acre. In addition, spraying 0.2% potassium dihydrogen phosphate, 0.1% borax, and 0.05% ammonium molybdate mixture on the first flowering stage can increase the rate of scarring and increase grain weight. 4 During the young period, 10-15 kg of compound fertilizer and 10 kg of urea should be applied per acre to promote the growth of soybean meal and increase the yield. 4, pest and weed control. The prevention and treatment of the diseases, diseases, and diseases of green soybeans are related to whether the pesticide residue of the soybean meets the international standards and whether the quality of the soybean meets the processing standards. It is a key link for the cultivation of low-yield soybean residues in soybeans. It is necessary to take into account the climatic conditions and the occurrence regularity of main diseases, weeds and weeds of soybeans. Corresponding preventive measures. According to the growth period of soybeans, the following prevention and control measures shall be formulated: 1 Before seedlings are sown, the weeds will be mainly controlled, and they may be treated with Dole 450 times liquid. 2 At the seedling stage, the spring soybeans are mainly used to control small tigers and blight, and can be controlled by the 600-fold liquid of Tianwang Baishu and the 750-fold liquid of Guangkuiling; autumn soybeans are mainly used to control whitefly and damp-blight, and the medicament is used for selection. Imidacloprid 1500 times + Guangjuling 750 times the control. 3 Before flowering, there were many types of pests and diseases at this stage. According to the occurrence of pests and diseases in the field, corresponding control measures were taken. Spring soybeans, Spodoptera littoralis adults began to appear in early April, with a “spring†attractant to kill adult, if spotted whitefly and spider mite damage in the field, can be used imidacloprid 1500 times solution + Bazhi Ling 1000 times solution Prevention. Autumn soybeans, before flowering to control spotted fly, whitefly, etc., mainly used imidacloprid 1500 times liquid + lag 3000 times liquid. In addition, due to adverse effects of pollination and fertilization on the flowering phase of soybean, in order to avoid the damage of soybean meal, downy mildew and powdery mildew during the flowering stage, buddweed can be used with 750-fold solution of methomyl and 600 times liquid of Kimreda-Mill + cyanobacteria. Oxazole 1000 times to control the above three kinds of pests and diseases. 4 Infestation period, the main insect pests in this period include whitefly, soybean meal, and Spodoptera litura. Medicaments can be used with Mobilang 1500 times liquid and 10% over 3000 times liquid; diseases can prevent downy mildew and anthracnose, and medicaments can be used. Jin Lei Duomi 600 times liquid + thiophanate-methyl 600 times. 5 Before harvest, the main prevention and treatment of Spodoptera litura, soybean meal and anthracnose mainly based on the occurrence of pests and diseases, in the 15-20 days before the harvest, you can spray 3750 times the beating liquid + belched for 1000 times. Stop using pesticides 15 days before picking. At this time, if any eggs are found in the field, they must be picked and concentrated in time.
