Abstract

The invention relates to the technical field of controlled-release fertilizers and particularly relates to a special coated controlled-release fertilizer for peanuts in a high yield field. The specialcoated controlled-release fertilizer is formed by an outer layer, a middle layer and an inner layer; a pest control component, a pest control component, a growth promotion component and a premature senescence prevention component are combined together, so that the releasing period is controlled, and the fertilization efficiency is improved; the fertilizer does not need to be applied in the wholegrowth cycle, so that the labor cost is reduced, and the fertilizer has the positive influence on the increase of yield and the improvement of 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 high-yield fields, and also relates to a preparation method for special-coated controlled-release fertilizers for high-yield fields. Background technique [0002] Peanut production can not only effectively guarantee the safe supply of edible oil in my country, but also is a bulk agricultural product with strong international competitiveness in my country. With my country's accession to the WTO and the gradual opening of the domestic market to the international market, agricultural products such as wheat, corn, and soybeans with a high degree of mechanization, large-scale production, and low production costs have poured into our country in large quantities, and then impacted the domestic market. Peanut still has a relatively large price advantage in the world, and has always been in a favorable p...
