Embodiment 1

[0019] A method for improving the slow-release effect of manure organic fertilizer, comprising the following steps:

[0020] (1) After mixing wakame and bamboo shoot shells according to the ratio of 10:1, dry them, then crush them through a 40-mesh sieve, then add clear water to it according to the ratio of liquid to material volume ratio of 30, and then according to the enzyme concentration of 300U Add cellulase to it per ml, and after 3 hours of enzymatic hydrolysis reaction, a wakame enzymatic hydrolysis solution is obtained, wherein the temperature of the enzymatic hydrolysis reaction is 55° C., and the pH value is 5.0;

[0021] (2) After the solid-liquid separation of poultry and livestock feces, the solid feces are collected. In parts by weight, 80 parts of solid feces, 20 parts of straw powder, and 10 parts of sawdust are sequentially added to the fermentation tank, and then the compound microbial bacteria are added thereto agent, mixed and stirred evenly, a fermentatio...

Embodiment 2

[0024] A method for improving the slow-release effect of manure organic fertilizer, comprising the following steps:

[0025] (1) After mixing wakame and bamboo shoot shells according to the ratio of 15:1, dry them, then crush them through a 40-mesh sieve, then add clear water to it according to the ratio of liquid to material volume ratio of 35, and then according to the enzyme concentration of 350U Add cellulase to it per ml, and after enzymatic hydrolysis reaction for 3.5 hours, obtain wakame enzymatic hydrolysis liquid, wherein the temperature of enzymatic hydrolysis reaction is 58 ℃, and the pH value is 5.0;

[0026] (2) After the solid-liquid separation of poultry and livestock feces, the solid feces are collected. In parts by weight, 85 parts of solid feces, 25 parts of straw powder, and 13 parts of sawdust are sequentially added to the fermentation tank, and then the compound microbial bacteria are added thereto. agent, mixed and stirred evenly, a fermentation treatment...

Embodiment 3

[0029] A method for improving the slow-release effect of manure organic fertilizer, comprising the following steps:

[0030] (1) After mixing wakame and bamboo shoot shells according to the ratio of 20:1, dry them, then crush them through a 40-mesh sieve, then add water according to the ratio of liquid to material volume of 40, and then according to the enzyme concentration of 400U Add cellulase to it per ml, and after enzymatic hydrolysis reaction for 4 hours, a wakame enzymatic hydrolysis solution is obtained, wherein the temperature of the enzymatic hydrolysis reaction is 60° C., and the pH value is 5.0;

[0031] (2) After the solid-liquid separation of poultry manure, the solid manure is collected, and in parts by weight, 90 parts of solid manure, 30 parts of straw powder, and 15 parts of sawdust are sequentially added to the fermentation tank, and then the compound microbial bacteria are added thereto agent, mixed and stirred evenly, a fermentation treatment for 25 days, ...

Abstract

The invention discloses a method for improving the slow release effect of a manure organic fertilizer, and the method comprises the following operation steps: (1) mixing Undaria pinnatifida and bambooshoot shells, drying, pulverizing, adding cellulase into the mixture, and carrying out enzymolysis reaction to obtain Undaria pinnatifida enzymolysis liquid; (2) after solid-liquid separation of livestock manure, collecting to obtain solid manure, and performing primary fermentation treatment on the solid manure for 20-25 days to obtain a primary fermentation product; (3) evenly mixing the primary fermentation product and the Undaria pinnatifida enzymolysis liquid, performing natural fermentation treatment, granulating the secondary fermentation product by a disc granulator, and drying to obtain a finished product. The organic fertilizer prepared by the method has many nutrient components, can effectively improve the soil, improve the soil fertility and the utilization rate of nutrient resources, and the organic fertilizer prepared by the method has excellent slow release effect, and can effectively provide nutrients for crops for a long time.

Description

technical field [0001] The present invention relates to the technical field of preparation of poultry manure organic fertilizer, in particular to a method for improving the slow-release effect of manure organic fertilizer. Background technique [0002] At present, the large-scale application of chemical fertilizers and low utilization rate have caused a large amount of unused nitrogen and phosphorus to enter the ecological environment, polluting the environment, and long-term application of chemical fertilizers has caused soil degradation and ecological deterioration such as soil compaction, organic matter reduction, and microbial shortage. The application of organic fertilizer can increase the content of soil organic matter, improve the living conditions of soil microorganisms, promote the formation of soil aggregate structure, improve the cohesion and adhesion of soil, and improve soil fertility. The application of organic fertilizers makes the soil nutrients more comprehe...
