Culture medium for edible fungus and preparation method thereof

Abstract

The invention discloses a culture medium for edible fungus and a preparation method thereof. The culture medium comprises the following raw materials: 10 to 20 parts of weed tree sawdust, 35 to 40 parts of corncob, 10 to 20 parts of bagasse, 15 to 25 parts of wheat bran, 3 to 8 parts of corn flour, 2 to 7 parts of bean pulp, 30 to 40 parts of pleurotus eryngii fungus residues, 8 to 12 parts of cow manure, 9 to 12 parts of corn stalk, 1 to 5 parts of calcium carbonate, 1 to 5 parts of lime, 2 to 3 parts of gypsum, 1 to 5 parts of a compound fertilizer, 2 to 6 parts of calcium superphosphate and 11 to 20 parts of bentonite. The culture medium has a pH value of 7.5 to 8 and water content of 65 to 68%. The culture medium for the edible fungus and the preparation method designed by the invention can ensure the growth rate and color of the edible fungus, improve the nutritional value of the edible fungus, reduce cost and improve yield of the edible fungus.

Description

technical field [0001] The invention belongs to the field of edible fungus cultivation, in particular to an edible fungus culture material and a preparation method thereof. Background technique [0002] During the cultivation process of edible fungus, the compost needs to maintain a certain water content, especially in the process of outdoor composting, fermentation and turning over of the compost, it is usually necessary to pay attention to watering or pouring out human excrement and biogas slurry according to the dryness and wetness of the compost etc. Make the compost wet to ensure that the water content of the compost is 65-67%, to prevent the compost dryness due to water loss during the secondary fermentation process, so as to ensure that the compost fermentation is even and fully decomposed; because in this process , The operation to ensure the amount of water is carried out manually, and it is prone to unstable water content in the compost. For example, if you forget ...

[0002] During the cultivation process of edible fungus, the compost needs to maintain a certain water content, especially in the process of outdoor composting, fermentation and turning over of the compost, it is usually necessary to pay attention to watering or pouring out human excrement and biogas slurry according to the dryness and wetness of the compost etc. Make the compost wet to ensure that the water content of the compost is 65-67%, to prevent the compost from drying out due to water loss during the secondary fermentation process, so as to ensure that the compost is fermented evenly and fully; , the operation to ensure the amount of water is carried out manually, and it is prone to unstable water content in the compost. For example, if you forget to add the compost, the compost will be dry, which will affect the growth of edible fungi to a certain extent.
