Abstract

The invention discloses a preparation method for compound fertilizer special for high-yield green rice. The preparation method comprises the following steps that chicken manure, decomposed cow dung, camellia oil cakes, peanut shell powder, straw powder, zeolite powder and calcined kaolin are uniformly mixed, water is added, an EM strain stock solution is added, complete mixing is carried out, andfermenting is carried out so as to obtain a fermented material; and EDTA(ethylene diamine tetraacetic acid) chelated manganese, ferric nitrate hexahydrate, ammonium sulfate, ammonium hydrogen phosphate, plant ash, calcium-magnesium phosphate fertilizer, gypsum powder and a hydrophobic slow-release agent are added in the fermented material, uniform mixing is carried out, and granulating and dryingare carried out so as to obtain the compound fertilizer special for the high-yield green rice, wherein the hydrophobic slow-release agent is prepared through a process which comprises the following steps of uniformly mixing silicon dioxide hydrogel, dodecyltrimethylammonium bromide, fatty alcohol-polyoxyethylene ether and water, sequentially adding alpha,omega-dihydroxy polydimethylsiloxane, octadecyltrimethoxysilane and oxidized polyethlene wax in a stirring state, carrying out stirring continuously and carrying out homogenizing treatment so as to obtain the hydrophobic sustained-release agent.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a method for preparing special compound fertilizers for high-yield green rice. Background technique [0002] my country is a large agricultural country, and the continuous increase of population makes my country's grain production must be high-quality products. In recent years, in order to solve the threat of plant diseases and insect pests to organic rice cultivation, my country has introduced a variety of organic rice fertilizers, but biological pesticides and chemical pesticides are used in the production process, and the yield is low and the quality is poor. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a method for preparing high-yielding green rice-specific compound fertilizer. The obtained compound fertilizer is not only rich in nutrients, but also can significantly increase th...
