Preparation method for bio-organic fertilizer specially used in saline-alkali field

Abstract

The invention discloses a preparation method for a bio-organic fertilizer specially used in a saline-alkali field. The method comprises the following steps: (1) crushing edible fungus waste, and performing sterilization after crushing; (2) mixing the sterilized edible fungus crushed matter and manure of livestock and poultry, and adding an organic matter fermentation agent in the mixing process; (3) performing high-temperature fermentation for 25-40 days after mixing, and uniformly mixing the fermented material and microbial active matter according to a ratio; and (4) drying the mixture, and performing crushing to obtain the bio-organic fertilizer. The bio-organic fertilizer provided by the invention can fully satisfy the nutrient needs of plants in the saline-alkali field, simultaneouslyhas the effects of water conservation, fertilizer maintenance, slow release, improvement of saline-alkali soil and the like, improves the utilization ratio of a chemical fertilizer, and reduces environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of biological organic fertilizers, and in particular relates to a preparation method of special biological organic fertilizers for saline-alkali land. Background technique [0002] The salt in the soil of saline-alkali cultivated land is very harmful to the root system of crops. After the root system of crops is poisoned by salt, the root system will be poorly developed and prematurely senile. There is a lot of salt in the soil of saline-alkali land, and there are often white saline-alkali deposits on the soil surface, poor ventilation and water permeability, and the root systems of crops are often poisoned, rotten, and dead. output negative effects. [0003] In recent years, the garbage crisis caused by the increasing amount of edible fungus waste has become a serious problem. Because edible fungus waste usually has its special physical and chemical properties and rich nutrients, people began to pay atten...

AI Technical Summary

Problems solved by technology

Because edible fungus waste usually has its special physical and chemical properties and rich nutrients, people began to pay attention to using it to improve saline-alkali soil, so as to reduce economic investment, reduce pollution, and reduce soil salinity, pH value, alkalization, etc. degree, changing soil properties, reducing bulk density, increasing porosity and increasing soil nutrients have achieved different degrees of effect, but it still does not have the advantages of improving soil structure, reducing soil salinity and improving soil fertility and biological activity.
