What are the advantages of plastic film planting spring kidney beans compared with traditional planting? How to do cultivation management?

Apply sufficient base fertilizer to ensure sufficient nutrients. Apply 2000 kg of farm manure and 40-50 kg of compound fertilizer per mu as base fertilizer. Top dressing should be done in time, and compound fertilizer 10- 15 kg should be applied appropriately at the initial stage of flowering and pod setting. After sowing, compact the plastic film to prevent it from being damaged by strong wind. For the plots suitable for mechanized operation, the ridging sowing and covering machine can be used to improve the efficiency. Spring kidney beans covered with plastic film grow faster, and it usually takes about 50 days from sowing to harvesting pods. Kidney beans are familiar to everyone. As can be seen from its name, it does not need scaffolding during its growth. Its plants are short. After the main stem grows for 4-8 days, the terminal bud is formed and the inflorescence is no longer elongated. Lateral branches or inflorescences germinate in the axils of each node, and they also form inflorescences after a few days of growth. Flowers and pods dig deep into the ground, apply sufficient fertilizer and irrigate the bottom water. Select high-quality disease-resistant varieties, and seed dressing with seed coating agent and new high-fat film (which can effectively isolate virus infection, not affect germination and imbibition functions, strengthen respiratory intensity and improve seed germination rate).

Sweet beans do not need to be shelved, and the planting management is relatively simple, saving time and effort. Generally, sweet beans No.1 and No.2 are widely planted. In particular, the terrain that is not conducive to scaffolding can be planted at will, and beans carefully managed during the growing period can be picked every day. After the main stem grows for 4 ~ 8 days, the terminal bud is formed and the inflorescence is no longer elongated; The lateral branches or inflorescences occur in the axils of each node, and the terminal buds also form inflorescences after the lateral branches grow for several days; The growth period is generally 50 ~ 60 days; There are few inflorescences, flowers and pods, and the yield per mu is about 2000 ~ 2500 kg. The harvesting period is concentrated, which is suitable for mechanized cultivation.

Kidney beans are planted in spring and autumn every year, with spring around March and autumn around August-September. Some areas with high temperature can be planted in advance, and areas with low temperature can be delayed. Through experimental screening, the planting area of super gluten-free Jiedouwang, Lvlong No.4 and purified Zaozhuang semi-frame with dark green fruit color, large fruit shape and high and stable yield was expanded, and the variety upgrading was accelerated. After two years of efforts, the coverage rate of improved kidney beans in our district has reached over 98%.
