Abstract

The invention relates to the technical field of controlled-release fertilizers, in particular to a special coated controlled-release fertilizer for peanuts in acid soil. The special coated controlled-release fertilizer consists of an outer layer, a middle layer and an inner layer. Components for improving stress resistance, promoting seedling growth, controlling plant diseases and insect pests andactivating calcium ions to promote full pods are combined together to control the controlled-release period, so that fertilizer applying efficiency is improved; and whole growth period does not needtopdressing, so that the 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 acidic soil, and also relates to a preparation method of the special-coated controlled-release fertilizer for peanuts in acidic soil. 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. Peanut is a crop that requires a large amount of calcium. For every 100 kg of pods formed, the amount of calcium absorbed reaches 2.0–2.5 kg. Calcium deficiency will lead to empty peanut shells and rotten fruits. Peanuts in the southeast coast of my country are mainly planted in dry sandy land. The soil...
