Grain type humic acid compound biological fertilizer and manufacturing method therefor

Abstract

The invention discloses a particle-typed biological composite fertilizer and preparing method of humic acid, which is characterized by the following: adopting low-temperature graining and drying without breaking germ; dispensing solid particle typed fertilizer of humic acid, biological bacterial fertilizer and middle and trace element with weight rate at 2: (0. 1-0. 2): (0. 05-0. 1) through effective compatibility of microbe composite germ and humic acid and relative element; solving the coordinate action of each bacteria in the composite microbe fertilizer without mutual antagonism; making the bacteria display heat-proof property; blending the microbe and fitful quantity of azophoska fertilizer to act; fitting for increasing production and effectiveness in the agricultural domain.

Description

technical field [0001] The invention relates to the field of a humic acid microbial compound fertilizer, in particular to a granular humic acid biological compound fertilizer and a manufacturing method thereof. Background technique [0002] Humic acid is the remains of animals and plants, mainly the remains of plants. It is a kind of macromolecular organic weak acid mixture accumulated after the decomposition and transformation of microorganisms, as well as a series of changes in geochemistry and physics. Humic acid widely exists in soil, peat, lignite, weathered coal, oceans, lakes and swamps, and natural water also contains a small amount of humic acid. The total amount of humic acid contained in the soil is the largest, but the average content is less than 1%; the total amount contained in brackish water is also a lot, but the concentration is lower, and it is impossible to develop it as a resource. Among them, the most promising humic acid resources to be developed and ...

Problems solved by technology

[0010] A large amount of urea is added to the current formula of humic acid compound fertilizer, which makes the organic matter in the soil decrease gradually, and the basic substances such as calcium and magnesium are deficient, so that the soil is acidified, the soil has no aggregate structure, and the conditions of water, fertilizer, gas and heat in the soil cannot be coordinated. , and high-concentration urea produces high-concentration ammonia poisoning in the process of hydrolysis, causing dangers such as yellowing of leaves and chlorosis symptoms of plants. At the same time, in the existing compound microbial fertilizers, the relationship between bacteria and bacteria They cannot interact and coordinate with each other, and they are antagonistic to each other. There are also microorganisms that are easily inactivated under high osmotic pressure after being mixed with high-content nitrogen, phosphorus, and potassium fertilizers, and microorganisms are prone to die after being heated during drying during the granulation process. current situation

[0011] The purpose of the present invention is to provide a new type of granular humic acid biological compound fertilizer and its manufacturing method, which aims to solve the problem that the various strains in the compound microbial fertilizer can interact with each other without antagonism, and the strain itself has heat resistance. characteristics, and low-temperature granulation and drying are used in the production process without destroying the bacteria. At the same time, through the effective compatibility of the microbial bacteria with humic acid and related elements, the microorganisms and the appropriate content of nitrogen, phosphorus, and potassium fertilizers are mixed to play a coordinated role.
