Method for cultivating edible fungi with cotton stalk column block type nutrition matrix

Abstract

The invention discloses a cultivating method of edible fungi, which comprises the step of taking 12 cm-18 cm cotton stalk as a main material and doping an auxiliary material to form column block type nutrition matrix for cultivating edible fungi; the edible fungi have one of following proportioning by weight: in the first formulation, the main material is 80-84 parts of cotton stalks, the auxiliary materials are 4-8 parts of soybean meal, 2-6 parts of wheat bran, 3-5 parts of lime, 1-3 parts of superphosphate, 1-3 parts of plant ash, and 0.08-0.12 parts of partricin; in the second formulation, the main material is 60-64 parts of cotton stalks, the auxiliary materials are 19-23 parts of cotton seed hulls, 4-8 parts of soybean meal, 2-6 parts of wheat bran, 2-4 parts of lime, 1-3 parts of superphosphate, 1-3 parts of plant ash, and 0.08-0.12 parts of partricin. The nutrition matrix is prepared by the following method: crushing the main material, softening the mixed materials, setting up fungi growing column blocks, and growing the fungi. According to the method provided by the invention, 12 cm-18 cm cotton stalks cut into sections are adopted as the main material, the expensive cotton seed hulls are not used or used in less quantity, so that the cost for crushing the cotton stalks is reduced 40%, the total cost is reduced, the production efficiency is improved, and meanwhile, then a new route for changing and utilizing the cotton stalks is found.

Description

technical field [0001] The invention relates to a method for cultivating edible fungi with cotton stalks, in particular to a method for cultivating edible fungi using crushed cotton stalks with a length of 12cm-18cm as the main material and adding auxiliary materials to make a column-type nutrient matrix. Background technique [0002] Cottonseed hulls are the main raw material for cultivating wood-rotten edible fungi. Due to the impact of supply and demand, the price rise has restricted the development of the edible fungus industry. The nutrient content of cotton stalks is 6.5% crude protein, 6.7% hemicellulose, 44.1% cellulose, 15.2% lignin, 0.65% calcium, 0.09% phosphorus, 0.03% free gossypol, and a C / N ratio of 30:1. Its crude fiber, soluble carbohydrates and C / N are slightly lower than those of cottonseed hulls, but its crude protein, cellulose and lignin contents are higher than those of main crop straws, and its dry matter effective degradation rate is 33.3%.

Problems solved by technology

However, in the existing technology of cultivating edible fungi, the cotton stalks are all finely crushed, and the length is controlled below 1 cm, which is used as the main material and put into a plastic bag to make a nutritional matrix.
