Problems solved by technology

However, the functional bacteria on the surface of the particles are not only prone to inactivation and loss during storage and application, but also easily affected by unfavorable survival factors in the soil environment after being applied to the soil, and the survival rate in the soil is reduced, resulting in The number of live bacteria is not enough, and the fertilizer effect is difficult to meet expectations, which limits the popularization and application of granular bio-organic fertilizers

Abstract

The invention discloses granular biological organic fertilizer. The organic fertilizer is prepared from the following raw materials in parts by weight: 400-500 parts of a decomposed organic material,100-150 parts of inorganic fertilizer, 40-60 parts of inorganic clay, 20-40 parts of humic acid, 20-40 parts of porous starch, 20-40 parts of expanded feather meal, 10-20 parts of activated sludge, 5-10 parts of microbial powder and 1-3 parts of a coated binder. The total effective viable bacteria count in the microbial powder is greater than or equal to 0.2*10<8>cfu/g. The granular biological organic fertilizer can effectively fix functional bacteria on fertilizer particles, the survival rate is high, the functional bacteria is not easy to lose, after applied into soil, can rapidly and massively multiply, and thus gives full play to the fertilizer effect and improves the yield of crops.

Description

technical field [0001] The invention relates to the technical field of novel fertilizers, in particular to a granular bio-organic fertilizer. Background technique [0002] Bio-organic fertilizer refers to a type of microbial fertilizer and organic fertilizer that is composed of specific functional microorganisms and organic materials that are mainly sourced from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. Fertilizer with fertilizer effect. Bio-organic fertilizers are mainly divided into two types: powder and granules. Granular bio-organic fertilizers are easy to store, transport, and apply, and are more popular in practical applications. The traditional bio-organic fertilizer production adopts the fermentation method. Functional bacteria and organic materials are mixed and fermented to produce bio-organic fertilizers. However, in the process of granulation and drying, due to the high tem...
