Method for preparing bacterial fertilizer from edible fungus chaff

Abstract

The invention discloses a method for preparing a bacterial fertilizer by utilizing edible fungus chaff, belongs to the field of microorganisms, and solves the problem that crude fibers in the existing bacterial fertilizer are difficult to degrade. The method comprises the following steps: primarily crushing the mushroom bran, the straw and the livestock and poultry manure; adding cellulose degrading bacteria, a decomposing inoculant, auxiliary materials and microbial growth nutrient elements, mixing, adjusting the C / N ratio, carrying out solid-state stacking fermentation, sieving, and returning the material with the particle size of more than 0.6 cm to the mixing step; adding a decomposing inoculant, raw cow dung, humic acid K and microbial growth nutrient elements into the sieved material with the particle size of not more than 0.6 cm, mixing, adjusting the C / N ratio, and carrying out solid-state stacking fermentation; the preparation method comprises the following steps: mixing the raw materials, granulating, adding a probiotic agent, plant nutrient trace elements and microbial growth nutrient elements, mixing, carrying out solid-state stacking fermentation, sieving, and returning an oversize product to the granulating step, wherein the undersize product is the prepared bacterial fertilizer. The bacterial fertilizer with high and stable fertilizer efficiency and comprehensive nutritional ingredients can be prepared.

Description

technical field [0001] The invention belongs to the field of microorganisms, and in particular relates to a method for making bacterial fertilizer by using edible fungus chaff. Background technique [0002] Mushroom chaff is the residue of the culture medium after the cultivation of edible fungi. It is a composite of edible fungus mycelium residues and crude fibers whose structure has undergone qualitative changes after enzymatic hydrolysis of edible fungi. The main substrates are sawdust and straw. , corncobs, bagasse, cottonseed hulls and other agricultural straws, distiller's grains, vinegar grains, etc., which contain rich amino acids, fungal polysaccharides, and trace elements such as Fe, Ca, Zn, Mg, etc., making them into fertilizers can not only solve the problem of The whereabouts of the fungus chaff, and the nutrients in it can be effectively used. However, although the cellulose, hemicellulose and wood in the fungus chaff have been degraded to a certain extent dur...
