Abstract

The invention discloses a coated controlled-release preparation for relieving soybean saline-alkali stress and a preparation method and application thereof. The preparation method of the coated controlled-release preparation comprises the following steps: preparing an organic fertilizer and a soil conditioner as nuclear materials; continuously adding a bonding agent; mixing and granulating; drying; wrapping with a controlled-release coating material. The prepared coated controlled-release preparation for relieving soybean saline-alkali stress is applied to saline and alkaline land for planting soybean, so that the utilization rates of the organic fertilizer and the soil conditioner can be increased, the surface oil layer of the saline and alkaline land keeps low salinity and high nutrition, stable growth of the soybean is promoted, the soybean yield is increased remarkably, an optimized management mode of sustainable utilization of saline-alkali soil resources is realized, a basis is laid for the management of saline and alkaline farmland, and peasant income is increased.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and relates to a coated slow-release preparation for alleviating soybean saline-alkali stress, a preparation method and application thereof. Background technique [0002] The problem of salinization of cultivated land in China is very serious. Saline-alkali soil is widely distributed, and nearly 1 / 5 of the country's cultivated land is salinized. Saline-alkali soil is not only poor in physical and chemical properties, but also generally low in soil fertility, which seriously endangers the sustainable development of agriculture. The existing saline-alkali land improvement often adopts water washing method, sand pressure method or chemical method, but the transformation period is long and the investment effect is slow, while the method of increasing chemical fertilizer can increase crop yield in a short period of time, but it will cause the increase of soil salinity, soil physical The propert...
