Abstract

The invention relates to the technical field of controlled-release fertilizers and in particular relates to a coated controlled-release fertilizer special for peanuts in a poor dry land. The coated controlled-release fertilizer is composed of an outer layer, an intermediate layer and an inner layer. Due to adjustment of a controlled-release formula, operations of promoting growth of young seedlings, improving drought resistance, controlling plant diseases and insect pests and preventing release of later premature senility components are closely combined with a growth cycle of the peanuts, so that topdressing is not needed in the whole growth cycle, and the labor cost is saved; and moreover, the drought resistance of the seedlings is enhanced, poor pod enrichment caused by later fertilizer-free premature senility is avoided, and positive effects are achieved for improving the yield and quality of the peanuts.

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 dry and thin soils, and also relates to a preparation method for special coated controlled-release fertilizers for peanuts in dry and thin soils. Background technique [0002] 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, improvement of soil fertility, and protection of the agricultural ecological environment. Peanuts in my country are mainly distributed in arid and semi-arid hilly areas. Due to insufficient rainfall in the growing season and large inter-annual fluctuations, about 70% of peanuts are subject to different degrees of drought stress, and the average yield reduction rate of peanuts ca...
