Culturing substrate for industrially cultivating agaricus bisporus and preparation method thereof

Abstract

The invention discloses a culturing substrate for industrially cultivating agaricus bisporus and a preparation method thereof, which belong to the technical field of cultivation of edible fungi. In the technical scheme, the culturing substrate consists of raw materials and auxiliary materials such as corn straws, wheat straws, chicken manure and gypsum, and is prepared by material preparation, mixing, primary fermentation and secondary fermentation; and the culturing substrate has the nitrogen content of between 2.0 and 2.2 percent, the pH value of between 7.5 and 8.2, the water content of between 65 and 70 percent, the total sugar content of between 10 and 18 percent and the reducing sugar content of between 0.3 and 0.9 percent, is deep brown, contains a large number of visible actinomyces, is non-sticky when held by hands, is elastic, smells like the flavor of bread, has small tension and can be scattered and broken by the hands, and over 65 percent of wax is removed from the straws. Compared with the prior art, the culturing substrate has the advantages of expanding the raw material source of the agaricus bisporus culturing substrate, realizing local acquisition of materials, lowering the production costs of raw materials and enhancing economic benefits; moreover, the culturing substrate has a reasonable formula, reliable physical and chemical property indexes and good social and economic benefits, is fully accordant with the growth requirement of the agaricus bisporus, and increases the yield of the agaricus bisporus in each square meter area by 6.96 kilograms and the profit in each square meter area by 63.96 yuan compared with those of the prior art.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to the technical field of the formulation and preparation method of a culture medium for industrialized cultivation of Agaricus bisporus. Background technique [0002] Agaricus bisporus is currently used as an edible fungus, and its production and market supply have greatly enriched people's material life. Since Agaricus bisporus is a regenerative fungus, it relies on the nutrients in the decomposed dung grass to grow, so the necessary culture medium for the growth of Agaricus bisporus has become the main subject of research. Due to the substantial increase in the sales of Agaricus bisporus in domestic and foreign markets in recent years, a lot of funds have been invested in the production of Agaricus bisporus, which has prompted the price of raw and auxiliary materials of Agaricus bisporus culture medium to continue to rise. Judging from the current material pric...

Problems solved by technology

It is common knowledge for those skilled in the art to use corn stalks instead of rice straw and wheat straw as the raw material for preparing Agaricus bisporus culture medium, but it can really be used in factories, with reasonable formulas and simple preparation methods. There are not many culture materials
