Method for producing oyster mushroom adding compost by using vinegar residues and peanut shells to serve as raw materials after joint processing

Abstract

The invention relates to the technology for producing high-quality oyster mushroom adding compost by using peanut shells and vinegar residues to serve as raw materials after joint processing and belongs to the technical field of agricultural production. The method can be applied to production of the oyster mushroom adding compost. The acid-alkali treatment, puffing drying processing and supplement nutrient adding processing are carried out on the two normal agricultural and food industrial leftovers including the peanut shells and the vinegar residues to produce the high-quality oyster mushroom adding compost, effects of increasing 5%-10% of the production are achieved on the basis of reducing compost raw material cost by more than 20%. The method solves the problem that the existing using ratio of the peanut shells and acid sludge is low, environmental pollution is serious and the like, turns waste into wealth and is high in social and economic benefits.

Description

technical field [0001] This patent is a technology for adding compost to produce high-quality oyster mushrooms in the field of agricultural production technology, and belongs to the technical category of edible fungus production in the field of agricultural technology. Background technique [0002] Pleurotus ostreatus belongs to the genus Pleurotus of the family Basidiomycetes Agaricaceae Pleurotus in biological taxonomy, scientific name: [Pleurotus otreatus (Fr.) Kummer], Chinese product name: Pleurotus ostreatus, place name: Beifeng bacteria, oyster Bacteria, etc., are widely cultivated edible fungi. [0003] Pleurotus ostreatus is rich in nutrients, and every hectogram contains 20-23 grams of protein, and the amino acid composition is complete, and the mineral content is very rich. [0004] The main raw materials of the traditional Pleurotus ostreatus culture medium are cottonseed hulls (90%-95%), bran or corn flour (5%-10%). The cost of raw materials is relatively high,...

AI Technical Summary

Problems solved by technology

[0009] Disadvantages: 1. The pH value of vinegar residue is too small, and it needs to be alkalized when it is used in the production of edible fungi

[0010] 2. The crude protein content of vinegar dregs is high, and the crude fiber content is too low. During the cultivation process of edible fungi, the vegetative growth stage is too vigorous, the carbon source is consumed too much, the stamina is insufficient in the middle and late stages of fruiting, and the output is low.

[0011] 3. The material is too fine, and the air permeability of the material is poor after bagging

[0016] Disadvantages: 1. The lignin content of macromolecular refractory substances in the crude fiber content is too high, accounting for more than 27% of the dry weight of peanut shells

[0018] 3. The lignin of peanut shells is closely combined, and the cellulose and hemicellulose that are easily absorbed and utilized by edible fungi are tightly contained, which makes it difficult to colonize the mycelia of edible fungi
