Spring Soybean Cultivation Techniques
1. Select varieties: Spring soybeans are special early-maturing varieties. The types of landlords we push include: Liaoxian No. 1, Zhejiang Agricultural No. 6, Taiwan 75, etc.
2. Appropriate early sowing: early maturing varieties, suitable for protection cultivation, in the city from mid-March to early April, using greenhouses or double sheds to cover seedlings with seedlings, seedling age is controlled in about 15 days, in 4 Move to Daejeon from the beginning of the month to the middle of the month. You can collect it in mid-June. Where seeds are planted in open field, they are generally sown from early April to mid-April, and must be covered with plastic film to keep warm and keep seedlings.
3, dense planting plants: early maturing varieties of dwarf stems, intensive Yingying, it must pay attention to planting dense planting. Generally, the average spacing is about 50 centimeters, and the plant spacing is about 25 centimeters, and the number of seedlings per mu is about 12,000.
4, increase fertilization material, early maturing varieties of short growth period, rod dwarfing more, it must pay attention to increase fertilization material, the general base Mushi decomposed organic fertilizer 1500 kilograms, superphosphate 50 kilograms or three-element compound fertilizer 60 kilograms, top dressing with quick effect Fertilizer-based, early application, split time, in order to achieve strong seedlings early. Generally, after planting, 5% diluted human fecal urine water 200 kg or 3% carbonic acid water 200 kg. A 30-kg compound fertilizer is applied per acre to the tree-fertilizer, and foliar fertilizers are sprayed during the pod-logging period. Generally, the mixture is sprayed with 0.5% potassium dihydrogen phosphate and 3% urea for 2 to 3 times. To promote the full pod, uniform color.
5. Pay attention to pest control: The available chrysanthemum pesticides at the seedling stage can control aphids. At the later stage, pests such as bean pod borers, borerworms and bean tussock moths can use 25% Chrysene Ester Emulsion 500 when the eggs begin to hatch larvae. Double fluid, control once every 4 to 5 days.
6. Applicable for harvesting: Fresh beans require that the bean cake be fresh green and full of green beans should be harvested.
