Variety selection Currently, the widely cultivated variety of bean is Zhiyin 28-2, which can be used for mulching cultivation in spring.
The suitable lower limit temperature for sowing beans during sowing is 14 ℃, and it should be sown when the temperature is stable through 4 ℃ before and after frost break. Bean seeding method can be the same as kidney bean (kidney bean) planting method, sowing with high ridge and low hole sowing and covering with plastic film. The row spacing is 65 cm, the hole spacing is 18-25 cm, 4000-5000 holes are planted per mu, 2-4 seeds are planted per hole, and the seeding amount is 2-3 kg.
Field management mainly pays attention to erasing the side buds below the first inflorescence and the flower buds above the first inflorescence. The leaf buds simultaneously plant the leaf buds in the mixed buds; the middle and upper side branches see the flower buds and top off. At the same time, pay attention to the top of the main vine after it climbs to the top of the rack in time to stimulate the growth of the side vine. The side vine will still top after seeing the flower bud.
The harvested beans are harvested in time after the pods are long enough. Delayed harvesting of grains swells, reducing the quality of the commodity and also affecting future pod growth. Take care not to damage other inflorescences, flower buds and vine leaves during harvesting.
