Biofertilizer with edible fungus residue as raw material and preparation thereof

Abstract

The invention discloses a biofertilizer with edible fungus residue as the raw material and preparation thereof. The invention relates to a biofertilizer with edible fungus residue as the raw material, and the biofertilizer comprises the following components by weight: 20-40 parts of pretreated Hypsizygus marmoreus fungus residue, 1-3 parts of matrine, and 4-10 parts of fermented cow dung. The fertilizer provided by the invention can enhance the drought resistance of crops, is especially suitable for use in saline-alkali soil, can improve soil and improve soil physical properties, and is beneficial to improving soil fertility.

Description

technical field [0001] The invention relates to a biological fertilizer. Background technique [0002] Most of the existing biological fertilizers are single biological fertilizers. Such as: nitrogen-fixing bacterial fertilizer, which is mainly composed of bacteria and fungi with nitrogen-fixing effect; another example: phosphorus bacteria, whose function is to decompose organic phosphorus in the soil, making it easy to be absorbed by plants; another example: bacteria, Its function is to decompose potassium compounds in the soil and make them into available potassium that can be absorbed and utilized by plants. These fertilizers can play their own roles when used alone, and partially meet the needs of plants for the three elements of nitrogen, phosphorus, and potassium. They do not produce the soil compaction phenomenon caused by long-term use of chemical fertilizers. But its shortcoming is: using above-mentioned three kinds of biological fertilizers alone can only solve ...

Problems solved by technology

But its shortcoming is: using above-mentioned three kinds of bio-fertilizers alone can only solve one aspect of the nutrition needed by plants, and the cost is high, and the dosage is large. deficiency or waste

[0006] Moreover, the agricultural microbial agents currently on the market are mainly single microbial strains, which are difficult to restore the micro-ecological structure. At the same time, the synergy between common strains and crops is weak, which is unfavorable such as improving plant stress resistance and root nutrient absorption. For example, the publication number is The patent application of CN102888356A discloses a method and application of using Bacillus subtilis to prepare microbial fertilizer

Although some compound microbial agents have appeared on the market, their functions are single, or their use methods are limited, and the effect of increasing crop production after use is still unsatisfactory. Composite microbial agent or fertilizer with comprehensive functions and good yield-increasing effect

[0007] Due to the long-term lack of investment in bio-fertilizer research in China, my country's bio-fertilizer industry still has problems of low overall level, insufficient technological innovation, and unstable product quality and application effects.
