1. Variety selection The altitude and climate difference across the province is quite different. Due to the strong regional nature of the soybean varieties, the selection must be selected and introduced by the local agricultural sector to prove that it is suitable for local cultivation. Practice has proved that Taiwan 292, Tiefeng 29, Tiefeng 30, 8157 soybean king these varieties are widely adaptable, disease-resistant, and can be selected for use throughout our province. Second, the selection of places to pay attention to reasonable crop rotation, generally suitable for the former selection of garlic, rape, carrot or vegetable plots. After harvesting the former crop, dig the ground, top-dressing, picking, and chopping. Excavate the ground 25 to 30 centimeters, apply enough basic fertilizer, 2000 kg of organic fertilizer per acre, 25 kg of compound fertilizer, dig into the earth with the digging. The north and west direction of Kaiyi is 120-150 cm wide, and the length depends on the field. The soil surface is finely crushed and leveled, so that the soil is filled with imaginary solids, which promotes the development of the soybean root system and is conducive to the formation of strong seedlings. Third, the sowing time According to local climate conditions, soybeans in early spring in the province in late March ~ April in the middle and early sowing. Generally used hole sowing, drilling, sowing depth of 3 to 5 cm, too deep affect the cotyledons unearthed, too shallow to affect germination emergence. Fourth, rational planting when planting should be due to species, according to local conditions, rather dilute not thick, give full play to individual advantages. In the early spring, the province has high temperatures and strong sunlight. The planting density should be larger. Generally, the row spacing is controlled at 30 centimeters and 50 centimeters, with 2 to 3 seeds per hole. If the soil is dry after sowing, it can be perfused with water once it is soaked, and then it will be withdrawn immediately after soaking, which will help the seeds germinate. The soil will be too wet and the seeds will not germinate due to lack of oxygen, even if they are rotten. Therefore, it is necessary to take drainage in Daejeon. V. Seedling management of field management: Although the temperature in early spring rises quickly, the ground temperature is relatively low. If conditions permit, it can cover the film and raise the temperature, which is beneficial to the emergence of whole seedlings and strong seedlings. Seedling stage: After the seed germinates and emerges, it is timely replanted or transplanted. Into the three-leaf stage, combined with cultivating grass, and time seedlings, Dingmiao, weak to stay strong, leaving 1 to 2 per hole, to promote balanced and robust seedling development. Flowering period: In the early flowering period, according to the seedlings, fertilizer can be top-dressed once. Generally, 10 kg of urea is applied per mu, and the topdressing is carried out together with the cultivator. In addition, foliar spray fertilizer was applied to the seedling stage, early flowering stage and drumstick stage of soybeans, and potassium dihydrogen phosphate, green fenwe and molybdenum fertilizers were applied to spray 700 to 100010-6 paclobutrazol at the initial flowering stage. 2 times, if it grows vigorously, it will spray for the second time after 15 days. It can strengthen the stem and increase the stress resistance and prevent falling flowers. Large amount of water is required during the flood season, and timely filling with drought will make the grains full. Sixth, diseases and pests prevention and control diseases mosaic disease, powdery mildew easier to occur, according to the type of disease selection fungicides. Insect pests include aphids, cardamom, and carnivora, etc. The spraying began at the beginning of flowering, spraying once every 15 days, and spraying 3 to 4 times.
