High-efficiency liquid biological organic fertilizer produced from edible fungus residues and preparation method thereof

Abstract

The invention relates to a high-efficiency liquid biological organic fertilizer produced from edible fungus residues and a preparation method thereof. The high-efficiency liquid biological organic fertilizer is prepared from the following raw materials in parts by weight: 25-50 parts of the edible fungus residues; auxiliary materials comprising 1-10 parts of potassium fulvate and 1-10 parts of calcium ammonium nitrate; a chelating agent comprising 0.2-1.0 part of sodium tripolyphosphate and 0.1-0.5 part of sodium polyacrylate; a biological auxiliary agent comprising 0.5-3 parts of carboxylase,1-3 parts of a proteolytic enzyme and 1-6 parts of bacillus gelatinosa; and an extraction solution comprising 40-60 parts of a 1% guanidine hydrochloride aqueous solution. With the edible fungus residues as the main raw material, through a new technology of liquefaction extraction and under action of various biological enzymes, the biochemical characteristics of various nutrients in the edible fungus residues are changed, the water dissolving rate and high water soluble property of active organic matters in the edible fungus residues are improved, and the nutrient effectiveness and the nutrient utilization rate of the auxiliary materials are greatly improved.

Description

technical field [0001] The invention relates to a high-efficiency liquid bio-organic fertilizer produced by edible fungus residue and a preparation method thereof, and belongs to the technical field of solid waste recycling and new liquid fertilizer. Background technique [0002] my country is a big producer of edible fungi, with an annual output of about 22 million tons, accounting for more than 70% of the world's total output, and a total output value of more than 60 billion yuan. With the development of the edible fungus industry, a large amount of edible fungus residues are produced every year. For every ton of edible fungi produced, 0.6 tons of mushroom residues are produced. The annual output of mushroom residues is about 13.2 million tons, which is a huge amount. Edible fungus slag is the culture medium waste left after harvesting products during the cultivation of edible fungi. The organic matter content of the fungus slag is about 35-75%, and the mineral nutrients n...

Problems solved by technology

[0007] 1. At present, edible fungus residues are mainly produced as organic fertilizers used as base fertilizers by means of solid physical mixing and fermentation. There are a large number of water-soluble active substances, proteins, polysaccharides, organic acids, various mineral nutrients, and microbial metabolites in edible fungal residues. Due to the complexity of different soil conditions and the production process of organic fertilizer itself and the physical and chemical properties of the product, the conversion of active ingredients in the application process is less than 40%, and the nutrients cannot be fully absorbed and utilized by the crops, slowing down the organic matter and mineral nutrients in the soil. The conversion rate in the medium, and the comprehensive utilization rate of active substances such as protein

[0008] 2. Under the background of vigorously promoting drought-resistant, water-saving agriculture and water-fertilizer integration, the widely used water-soluble fertilizers for spraying and drip irrigation are mainly chemical fertilizers due to the solubility requirements, with extremely low or no organic matter content. Long-term Use can easily cause soil compaction and secondary salinization of soil

As a result, multiple soil-borne diseases are caused, and the quality of agricultural products is reduced.
