Embodiment 1

[0017] The Pleurotus eryngii culture medium using Miscanthus as a substrate in this example includes the following components in proportion by mass: 5% soybean meal, 8% corn flour, 5% wheat bran, and 79% miscanthus (the variety is Xiangzamang No. 1 ), light calcium carbonate 2%, lime 1%.

[0018] The preparation method comprises the following steps:

[0019] (1) Pre-treatment of Miscanthus: collect Miscanthus stems and leaves, dry to a moisture content of <10wt%, and crush to a particle size of <0.5 cm;

[0020] (2) According to the mass ratio, 5% soybean meal, 8% corn flour, 5% wheat bran, 79% miscanthus (the variety is Xiangzamang No. 1), 2% light calcium carbonate, and 1% lime are weighed for each component , mix well, and serve.

Embodiment 2-5

[0027] Miscanthus species were selected as Wujiemang, Nandi, Xiangzamang No. 2 and Xiangzamang No. 3, and the rest of the components and composition ratios were the same as in Example 1.

[0028] Each treatment was inoculated with 100 bags for cultivation test. Each bag was filled with 400g of dry material. According to the conventional method, the material was mixed into bags, sterilized, and inoculated. , After 30 days of ripening and cultivation, it enters the management of fruiting, and records the situation of bacteria and fruiting. The four Miscanthus species were all suitable for the mycelia growth of Pleurotus eryngii, and they all produced mushrooms smoothly, with no significant difference in yield.

Abstract

The invention provides a pleurotus eryngii culture medium utilizing miscanthus sinensis as a matrix and a preparation method thereof. The pleurotus eryngii culture medium comprises the following components by mass percentage: 3%-8% of bean pulp, 5%-9% of corn powder, 3%-9% of wheat bran, 72%-82% of miscanthus sinensis, 1.8%-2.2% of light calcium carbonate and 0.8%-1.2% of lime. The invention further provides the preparation method of the pleurotus eryngii culture medium. The pleurotus eryngii culture medium which takes the miscanthus sinensis as a main part is used for cultivating the miscanthus sinensis; the biotransformation efficiency of the formula of the culture medium can be up to be more than 80%; the yield and the quality of pleurotus eryngii culture products can be improved and the production cost is reduced.

Description

technical field [0001] The invention relates to a pleurotus eryngii culture medium and a preparation method thereof, in particular to a pleurotus eryngii culture medium using miscanthus as a substrate and a preparation method thereof. Background technique [0002] Pleurotus eryngii ( Pleurotus eryngii ), has another name called Erythra chinensis, which is favored by consumers for its good taste and long shelf life. In recent years, the factory cultivation of this rare edible fungus has attracted much attention at home and abroad. Research practice shows that the industrial cultivation substrate of Pleurotus eryngii has a direct impact on its yield, quality and production cost. Therefore, the selection of appropriate medium is the basis for obtaining higher benefits in the industrial cultivation of Pleurotus eryngii. [0003] At present, the industrial cultivation substrate of Pleurotus eryngii uses sawdust, cottonseed hulls, corn cobs, etc. as the main carbon source, and b...
