Culture base stock used for cultivating edible fungi and preparation method thereof

Abstract

The invention discloses a culture base stock used for cultivating edible fungi and a preparation method thereof. The culture base stock comprises the following components in parts by weight: 800-1300 parts of fresh jam white wine vinasse, 450-900 parts of polygonum capitatum dregs, 30-500 parts of sawdust, 30-90 parts of cottonseed hull, 30-150 parts of wheat bran, 35-80 parts of calcium carbonate, 5-9 parts of calcium superphosphate, 4-7 parts of dipotassium hydrogen phosphate, 4-7 parts of magnesium sulfate, 20-50 parts of lime powder and 0.02-0.06 part of rare-earth fertilizer. The fresh jam white wine vinasse and polygonum capitatum dregs which are subjected to simple treatment serve as cultivation base stock of edible fungi, the culture base stock can meet the nutritional requirements of the growth of most of edible fungi, thereby especially being suitable for improving the output and quality of pleurotus eryngii, and realizing the innocent treatment and the resource utilization of fresh jam white wine vinasse and polygonum capitatum dregs, therefore, the policy for the development and utilization of new materials is met, and the sustainable development of wine industry, pharmaceutical industry and edible fungi industry is also facilitated.

Description

technical field

[0001] The invention relates to the field of agricultural science and technology, in particular to a culture material for cultivating edible fungi and a preparation method thereof. Background technique

[0002] With the increasing market demand for edible fungi, the amount of cultivation material has increased rapidly, the price of raw materials has risen, and the production cost has risen. As a by-product of brewing, Maotai-flavored liquor distiller's grains, except that some of the distiller's grains are used as roughage in pig farming and in the production of organic fertilizers, most of them are directly applied to the soil or thrown into the wild, causing soil acidification and environmental pollution; in addition, as Polygonum cephalum dregs, a by-product of pharmaceutical companies, are mostly thrown away as garbage, causing environmental pollution.
