Precocious Spring Soybeans adopt a small arch cover film to cover heat preservation cultivation techniques, aiming at early commodity listing and improving economic efficiency. But in the cultivation technology, we must grasp the following aspects: 1. Variety selection We should select suitable early-maturing, high-yield, and high-quality varieties such as “Tangdou 9701†and “Spring-Fengfeng†for facilities cultivation and heat preservation measures. 2. The choice of seedbed is to choose a block that is sheltered from the wind, sunny, warm and frost-free, and has a low groundwater level in the south of the block. The soil in the seedbed needs to be loose, free from impurities, disease-free, and drained. 3, timely sowing early implementation of greenhouses or small arch shed cultivation, sowing time can be advanced to mid-February to early March. When the seedlings are raised, they are covered with double membranes (the base film plus the shed film). When the seeds are just uncovered, the bottom membrane is pulled out in time to foster good health. 4, there are generally two kinds of nursery methods: one is the nutrition seedlings nursery, seedlings per mu need to be 20-25 meters, 7500-11000 nutrients, each seed sowing 2 seeds; the other is seedlings, each The acres need 8 to 10 square meters of seedbeds, spread the seed evenly on the seedbed, and then cover the soil. The subsoil can be made of stone powder or loose soil and then covered with soil. When planting, pay attention to pouring enough water to ensure that you broadcast all seedlings. 5, timely transplanting seedlings for seedlings, requiring the seedlings to grow to 1-2 true leaves timely transplanting; nutrition seedlings nursery, seedlings grow to three true leaves when transplanted in time. It is generally required to plant 20,000 plants per acre, 2 plants per hole (1 nutrient bowl), and 2525 cm plant spacing. 6, scientific fertilizer and fertilizer to promote the application of nitrogen and phosphorus potassium, early application of Miao Fei, re-apply Hua Tu Fei. General Mushi pure nitrogen 10? 12 kg, phosphorus pentoxide, potassium oxide 5 kg each. When transplanting, it is required to apply enough basic fertilizer, using 40 kg of superphosphate, 30 kg of ammonium bicarbonate, 10 kg of potassium chloride or 20-30 kg of ternary compound fertilizer per acre. Inadequate fertilizers can lead to short, low-yielding plant types and can affect the commercial quality of fresh oysters. Immediately after planting, the film was covered and compacted to open the trenches in the field to ensure smooth drainage.
