Abstract

The invention relates to the technical field of controlled-release fertilizer, in particular to special coated controlled-release fertilizer for peanuts in saline-alkali soil. The coated controlled-release fertilizer consists of an outer layer, a middle layer and an inner layer; by combining salt resistance enhancement, prevention of etiolated seedlings, pest control, growth promotion and promotion of pod enriching components, the release period is controlled, and the fertilizing efficiency is improved; topdressing in the whole growth period is avoided, so that labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of controlled-release fertilizers, in particular to a special-coated controlled-release fertilizer for peanuts in saline-alkali soils, and a preparation method for special-coated peanut-coated controlled-release fertilizers for saline-alkali soils. Background technique [0002] The self-sufficiency rate of edible vegetable oil in my country is less than 32%. To increase the self-sufficiency rate, we must expand the cultivated area. In order to avoid competing with others for food and land, it is important to vigorously expand planting in saline-alkali land and increase the total peanut output to ensure the safety of my country's edible oil supply. one of the ways. Peanut is one of the most widely cultivated oil crops in the world. It has the characteristics of wide adaptability, drought tolerance, barren tolerance and rhizobia nitrogen fixation. It is conducive to the development of water-saving agriculture...
