Embodiment 1

[0011] The preferred dispensing of the present invention is: comprise following composition by weight ratio: 20 parts of corn cobs, 23 parts of sawdust, 15 parts of white melon seed skins, 20 parts of bran, 5 parts of corn flour, 5 parts of soybean meal, 1 part of light calcium carbonate, 1 part lime. The white melon seed peel of the invention is pulverized, and the particle diameter is 0.2-0.4cm.

Embodiment 2

[0013] The preferred formulation of the present invention is: comprise the following composition by weight ratio: 25 parts of corn cobs, 23 parts of sawdust, 20 parts of white melon seed skins, 20 parts of bran, 5 parts of corn flour, 5 parts of soybean meal, 1 part of light calcium carbonate, 1 part lime. The white melon seed peel of the invention is pulverized, and the particle diameter is 0.2-0.4cm.

Embodiment 3

[0015] The preferred dispensing of the present invention is: comprise following composition by weight ratio: 25 parts of corn cobs, 24 parts of sawdust, 15 parts of white melon seed skins, 20 parts of bran, 8 parts of corn flour, 6 parts of soybean meal, 1 part of light calcium carbonate, 1 part lime. The white melon seed peel of the invention is pulverized, and the particle diameter is 0.2-0.4cm.

[0016] Following table is the comparison of three embodiments of the present invention also prior art formula

[0017]

[0018] The package in the "cost (yuan / package)" in the above table is 500g dry material. As can be seen from the table, the cost of the present invention is obviously lower than that of the prior art formula, and the appearance quality is also better than that of the existing formula.

Abstract

The invention belongs to the technical field of mushroom cultivation and particularly relates to a culture medium of pleurotus eryngii. According to the technical scheme, the culture medium of pleurotus eryngii is prepared from the following components in parts by weight: 20-25 parts of corncobs, 20-25 parts of sawdust, 15-25 parts of pumpkin seed hulls, 20 parts of bran, 5-10 parts of corn meal, 5-6 parts of soybean pulp, 1 part of light calcium carbonate and 1 part of lime. The culture medium which is suitable for growth and development of pleurotus eryngii is prepared according to nitrogen content and physical characteristics. Compared with a conventional formula, the culture medium has the advantages that the pleurotus eryngii production cost is lowered by 14.1%, the biotransformation rate is improved by 4.8% and the finished pleurotus eryngii ratio is improved by 20.9%. The pleurotus eryngii is good in shape, high in density and snow-white in color.

Description

technical field [0001] The invention belongs to the technical field of mushroom cultivation, and in particular relates to a cultivation substrate of Pleurotus eryngii. Background technique [0002] Pleurotus eryngii, also known as Pleurotus eryngii, belongs to the phylum Fungi, Basidiomycetes, Agaricaceae, Pleurotaceae, and Pleurotus. agaric. The meat is thick, crisp and tender, and has the aroma of almonds and the taste of abalone. It is known as the "King of Oyster Mushrooms". It is suitable for fresh-keeping and processing, and has a good market prospect. [0003] At present, the annual output of Pleurotus eryngii in the country is about 700,000 tons, and the production mode has shifted from seasonal cultivation to factory cultivation. Its main raw materials are wood chips, corncobs, bagasse, and cottonseed hulls, and the main materials account for about 63~66%; auxiliary materials It is bran, corn flour, soybean meal and cotton meal, and the auxiliary materials account...
