Amino acid foliar fertilizer produced with edible fungus residue as main material and preparation method thereof

Abstract

The invention discloses an amino acid foliar fertilizer produced with edible fungus residue as the main material and a preparation method thereof. The fertilizer adopts edible fungus residue as the main material, and takes waste molasses liquid, Chinese herbal medicine, shell powder, acacia leaf, rice bran, plant ash, naphthylacetic acid and indoleacetic acid, etc as the auxiliary materials. According to the characteristics of the raw materials, Aspergillus niger, Aspergillus oryzae and Bacillus licheniformis are employed for step fermentation in order, stirring is carried out continuously during fermentation, and quantitative oxygen is introduced regularly. Specifically, the Chinese herbal medicine is composed of lemna minor, cinnamomum camphora leaf, astragalus, acorus calamus and mint. The shell powder is prepared by drying and crushing of lobster shell or crab shell. The amino acid foliar fertilizer prepared by the method provided by the invention has an amino acid content of more than or equal to 30% and comprehensive nutrition, contains crop growth required macroelements, trace elements and growth regulator and a lot of active substances produced by fermentation, has high plant absorption and utilization rate, and has wide raw material sources and low price. Also, the production process has no pollution or sewage discharge, and is environment-friendly and sanitary.

Description

technical field [0001] The invention belongs to the technical field of fertilizers. More specifically, the invention relates to an amino acid foliar fertilizer produced from edible fungus residue as a main ingredient and a preparation method thereof. Background technique [0002] With the development of edible fungus industry, the amount of edible fungi dregs has increased sharply, but the utilization rate is low, about 35%. Edible mushroom residues are generally rich in protein, crude fat, crude fiber and trace elements, and also contain biologically active substances such as polysaccharides, organic acids, and enzymes. A large amount of mushroom residues have not been treated in an environmentally friendly manner and are discarded at will, which not only causes waste of resources, but also It is also prone to mildew and deterioration, pollutes land and water sources, and endangers human health. At present, the main utilization of edible fungus residues is stacking to pre...

AI Technical Summary

Problems solved by technology

[0003] There are two main ways to prepare organic fertilizers by using edible fungus residues. One is to use edible fungi residues as raw materials and use stacking fermentation to prepare organic fertilizers. The fermentation time is as long as more than 30 days, and the nutrients in organic fertilizers are relatively simple; One is to add a small amount to other raw materials to prepare organic fertilizer, and the amount of edible fungus residue is small, which cannot solve the problem of low utilization rate of edible fungus residue
