Culture base material for cultivating agaricus bisporus by edible fungus production waste and preparation method thereof

Abstract

The invention provides a culture base material for cultivating agaricus bisporus by edible fungus production waste and a preparation method thereof. The culture base material comprises the following raw material and auxiliary materials: the raw material is edible fungus production waste; the auxiliary materials comprise cotton seed hull, corn cob, wheat bran, plaster, lime, urea, calcium superphosphate and sugar, wherein the culture base material comprises the following materials in percentage by weight: 15+ / -1 percent of corn cob, 15+ / -1 percent of cotton seed hull, 12+ / -1 percent of wheat bran, 1+ / -0.1 percent of plaster, 3+ / -0.1 percent of lime, 1+ / -0.1 percent of urea, 2+ / -0.1 percent of calcium superphosphate, 0.5+ / -0.1 percent of sugar, 0.5+ / -0.1 percent of fermentation promoter and the balance of edible fungus production waste. The preparation method comprises the following steps of: weighing the corn cob, the cotton seed hull, the wheat bran, the plaster, the lime, the urea, the calcium superphosphate, the sugar, the fermentation promoter and the edible fungus production waste according to weight percentage; preparing; pre-wetting; mixing the raw material and the auxiliary materials; performing primary fermentation; bagging; and sterilizing under normal pressure to prepare the culture base material for cultivating agaricus bisporus. The culture base material has the advantages of rational formula, and simple and reliable preparation method; the cultivated agaricus bisporus has reliable quality, is low in cost and has good market prospect.

Description

technical field [0001] The invention relates to edible fungus cultivation technology, in particular to a medium material for cultivating Agaricus bisporus with waste materials from edible fungus production and a preparation method thereof. Background technique [0002] At present, the culture medium of Agaricus bisporus is mainly made of cottonseed hulls, rice straw, corn cobs, corn stalks, wood chips and other crop waste. Then there was a substantial increase. For example, cottonseed hulls were 0.15 yuan / catties in 2000, and have risen to 1 yuan / catties so far. With the increase in raw material prices, the cost of Agaricus bisporus cultivation and the risk of product sales have increased, resulting in a decline in the total cultivation. Therefore effectively exploiting the source of new culture material of Agaricus bisporus has become the top priority of this industry. In addition, after the production of fresh wood rotten edible fungi, most of the production waste is treate...

Problems solved by technology

[0002] At present, the culture medium of Agaricus bisporus is mainly made of cottonseed hulls, rice straw, corn cobs, corn stalks, wood chips and other crop waste. Then there was a substantial increase. For example, cottonseed hulls were 0.15 yuan / catties in 2000, and have risen to 1 yuan / catties so far. With the increase in raw material prices, the cost of Agaricus bisporus cultivation and the risk of product sales have increased, resulting in a decline in the total cultivation. Therefore, it has become an urgent task for the industry to effectively develop the source of new culture materials for Agaricus bisporus

In addition, after the production of fresh wood rotten edible fungi, most of the production waste is treated in the garbage mode, resulting in waste and great pollution to the environment
