Embodiment 1

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

[0018] The preparation method includes the following steps:

[0019] (1) Pretreatment of Miscanthus: Collect Miscanthus stalks and leaves, dry them to a water content of <10wt%, and then crush them to a particle size of <0.5 cm;

[0020] (2) According to the mass ratio of soybean meal 5%, corn meal 8%, wheat bran 5%, miscanthus 79% (species Xiangzamang No. 1), light calcium carbonate 2%, lime 1%, weigh 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 remaining components and the composition ratio were the same as in Example 1.

[0028] Inoculate 100 bags for each treatment for cultivation test. Each bag is packed with 400g dry material, bagged, sterilized, and inoculated according to the conventional method. After inoculation, place it in a culture room at 25°C for bacterial growth, and wait until the mycelium is full of the bag , And then enter the fruiting management after 30 days of mature cultivation, and record the growth and fruiting situation. The 4 miscanthus varieties are all suitable for the growth of the mycelium of Pleurotus eryngii, and they can produce smoothly, with no significant difference in yield.

Abstract

A Pleurotus eryngii medium using Miscanthus as a substrate and a preparation method thereof, the Pleurotus eryngii medium comprises the following components in proportion by mass: soybean meal 3-8%, corn flour 5-9%, wheat bran 3- 9%, miscanthus 72-82%, light calcium carbonate 1.8-2.2%, lime 0.8-1.2%. The present invention also includes the preparation method of the pleurotus eryngii culture medium. By using the Pleurotus eryngii culture medium mainly composed of Miscanthus eryngii to cultivate Pleurotus eryngii, the biotransformation rate of the medium formula can reach more than 80%, which can improve the output and quality of Pleurotus eryngii products and reduce production costs.

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...
