In order to create a good growth environment for beans, beans need to be planted in loose and breathable soil with deep soil layer, sufficient fertility and good drainage. At the same time, because the root of beans is more efficient for nutrient transportation and utilization in acidic soil, it is best to choose weak acidic soil. In order to improve the yield and quality of beans, it is also necessary to avoid planting legumes in the soil within 2-3 years. 1、 What kind of soil is better for planting beans? Choose the soil with loose and breathable, deep soil layer, sufficient fertility and good drainage to plant beans. The growth of beans needs to absorb enough nutrients from the soil, and deep soil is more conducive to the extension of bean roots. The poor and shallow soil may make the beans thin and short due to insufficient fertility, which will have an adverse impact on the yield of beans.
The soil has good drainage, which can maintain the soil water content in an appropriate range when the rainy weather lasts for a long time, so as to avoid bean root diseases or suffocation. In addition, bean roots can improve the rate of absorbing soil nutrients in acidic environment, so beans grow best in slightly acidic soil. When the soil is too acidic, quicklime should be used for regulation and neutralization. 2、 What kind of fertilizer is better for planting beans? 1. Base fertilizer: in order to ensure the growth of beans, it is necessary to apply sufficient base fertilizer to the soil before sowing beans. The fully decomposed farmyard fertilizer, urea, calcium superphosphate and other fertilizers can be selected as the base fertilizer, and the amount of fertilization needs to be adjusted according to the original fertility of the soil.
2. Topdressing: Topdressing of beans needs to be carried out according to different growth periods. In the period of vine growth, less fertilizer should be applied to prevent overgrowth, while the amount of nitrogen, phosphorus and potassium can be increased in the period of flowering and pod setting. At the same time, for the growth and yield of beans, it is also possible to apply fertilizer outside the root and spray an appropriate amount of foliar fertilizer on beans. （ChongDouJiaoYongShenMeTuBiJiaoHao）
