Problems solved by technology

[0003] At present, the bio-organic fertilizers on the market mainly use livestock and poultry manure, peat, and decomposed coal as organic raw materials. Single livestock and poultry manure is difficult to carry out large-scale production due to its slow fermentation, heavy air pollution, and large-scale occupation. Mass production, after being applied to the soil, if it is not fully decomposed, it will cause burnt seedlings
However, peat and differentiated coal are difficult to dissolve in the soil, and the organic matter and humic acid in it are difficult to be used by crops, which affects fertilizer efficiency.

Abstract

The invention provides a sustained-release microbial compound fertilizer and a preparation method thereof, belonging to the technical field of fertilizer production. The compound fertilizer comprises 160 parts of a fertilizer core and 3 to 5 parts of a coating that coats the fertilizer core. The fertilizer core comprises, by weight, 8 to 25 parts of polyacrylamide, 5 to 10 parts of tryptophan, 5 to 10 parts of threonine, 2 to 7 parts of sodium trimetaphosphate, 3 to 8 parts of sodium tripolyphosphate, 3 to 5 parts of EDTA and 50 to 60 parts of a microbial compound. The coating comprises, by weight, 2 to 6 parts of gelatin, 1 to 6 parts of polyvinyl alcohol, 20 to 40 parts of urea, 5 to 25 parts of ferrous sulfate, 5 to 25 parts of zinc sulfate, 3 to 5 parts of rice stalk, 15 to 25 parts of high-polymer chitosan and 30 to 55 parts of water. The sustained-release microbial compound fertilizer is high in fertilizer efficiency, ecologically safe, simple to prepare, low in cost and suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a slow-release microbial compound fertilizer and a preparation method thereof. Background technique [0002] In recent years, the production and consumption of slow-release / controlled-release fertilizers at home and abroad have been growing steadily, mainly for non-agricultural fields and consumer households, and no major breakthroughs have been made in the agricultural field. They are veritable "noble fertilizers" . my country is a big country in the production and application of chemical fertilizers, but it is not yet a powerful country in the production and application of chemical fertilizers. At present, global inflation, food and energy are all rising. Although my country's food production has increased for many years in a row, the rapid rise in the prices of chemical fertilizers and other agricultural materials still brings a certain degree of hid...
