Method for cultivating pleurotus geesteranus with straw and waste mushroom residue

Abstract

The invention discloses a method for cultivating pleurotus geesteranus with straw and waste mushroom residues. The method comprises the following steps: I, analyzing the contents of nutrient components of needle mushroom residues, namely, analyzing lignin, cellulose and board cellulose in the needle mushroom residues, testing the content of protein in the mushroom residues, testing the types of amino acid, analyzing and testing trace elements of the mushroom residues by using an ultraviolet / visible spectrophotometer, a chromatography method and an atom absorber, and detecting nutrient components in different mushroom bags, particularly the ratio of elements CN in the mushroom bags; II, screening the most appropriate pleurotus geesteranus strains cultivated by using the needle mushroom residues, and screening needle mushroom strains applicable to degrading mushroom residues; III, according to the biological characteristics of the pleurotus geesteranus, combining crop straw and needle mushroom, on the basis of different ratios of the crop straw to the mushroom residues, screening an optimal formula of a needle mushroom residue culture medium, adopting the needle mushroom residues as a substitution material to cultivate pleurotus geesteranus, thereby establishing a production system for cultivating pleurotus geesteranus by using the needle mushroom residues.

Description

technical field [0001] The invention relates to a method for preparing pear mushrooms from straw and waste fungus chaff. Background technique [0002] The current planting methods of xiuzhen mushrooms are still limited to seasonality, and most areas still produce mushrooms in winter. During the process of sterilization, germination and cultivation of xiuzhen mushrooms, the traditional production mode is mainly used, resulting in the The finished product rate is low, the fruiting time is inconsistent, and the biotransformation rate is low. Due to the rapid development of the edible fungus industry in recent years, the demand for raw materials has increased, and the cost of raw materials has soared. However, the traditional cultivation and management methods cannot effectively improve the yield. The quantity and quality of mushrooms. In addition, the prosperity of the edible fungi industry has brought about environmental problems. The current method of dealing with edible fung...

[0002] The current planting methods of xiuzhen mushrooms are still limited to seasonality, and most areas still produce mushrooms in winter. During the process of sterilization, germination and cultivation of xiuzhen mushrooms, the traditional production mode is mainly used, resulting in the The finished product rate is low, the fruiting time is inconsistent, and the biotransformation rate is low. Due to the rapid development of the edible fungus industry in recent years, the demand for raw materials has increased, and the cost of raw materials has soared. However, the traditional cultivation and management methods cannot effectively improve the yield. The quantity and quality of mushrooms. In addition, the prosperity of the edible fungi industry has brought about environmental problems. The current method of dealing with edible fungus waste is to discard or burn it, which not only causes waste of resources, but also leads to the growth of mold and pests, thereby polluting the environment. The waste from bacterial cultivation is not effectively utilized
