Abstract

The invention discloses a method for preparing sustained-release fertilizer capable of improving the stress resistance of rice. The method comprises the following steps: S1, grinding soybean meal, tearesidues and mushroom residues, mixing with pig manure, heating at high temperature, cooling to room temperature, adding organic acid, straw powder and biological bacteria, uniformly mixing, and fermenting to obtain a material A; S2, mixing ground phosphate rock, ground potassium ore, trace element fertilizer, polypeptide urea, monopotassium phosphate, potassium chloride, rooting powder and organic clay with the material A, and granulating to obtain a material B; and S3, coating the material B to obtain the sustained-release fertilizer capable of improving the stress resistance of rice. According to the preparation method, the sustained-release fertilizer prepared by optimizing the preparation process has good sustained-release effect and high fertilizing utilization, the stress resistance of rice can be improved after the fertilizer is applied, the rice yield can be effectively increased, and the rice quality can be improved.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a preparation method of a slow-release fertilizer for improving stress resistance of rice. Background technique [0002] With the increase of population pressure, the contradiction between large population and insufficient food supply has become increasingly prominent, and how to increase food production is an urgent problem. Rice is one of the main food crops in our country and occupies an extremely important position in food security. Increasing rice production will have far-reaching significance for the development of our national economy and social stability. The development of modern agriculture is inseparable from the production and use of fertilizers. Reasonable selection of each component and its content in fertilizers can not only provide nutrients for rice growth, but also effectively regulate rice growth and development and increase rice yield...
