Culture medium for low-cost pleurotus eryngii

Abstract

A culture medium for low-cost pleurotus eryngii comprises the following ingredients by weight percent: 70-75% of wheat straw, 10-15% of cotton seed, 5-10% of soybean powder, 0.3-0.5% of glucose, 0.5-1% of quick lime, 1-2% of hydrated lime, 0.1-0.2% calcium superphosphate and 0.1-0.2% of magnesium sulphate; the wheat straw is soaked in water in a fermentation pool for more than 20 days, and is then dried properly to have a water content of 25-35%; the total water content of the culture medium is 70-75%; the wheat straw, the cotton seed and the soybean powder are mixed according to respective ratio, and the rest of nutrition ingredients are scattered on the upper surface of or in the upper layer of the culture medium; the culture medium is tightly compressed, and the void ratio is lower than 10%. The culture medium adopts low-cost and reachable materials, the nutrition ingredients can satisfy the requirement for the growing of the pleurotus eryngii, and can facilitate the domestic manufacturing of pleurotus eryngii by a peasant.

Description

technical field [0001] The invention relates to a low-cost Pleurotus eryngii culture medium, which is a medium for cultivating Pleurotus eryngii. The material cost of the medium is low, and belongs to the field of culture medium. Background technique [0002] Pleurotus eryngii, also known as Pleurotus eryngii, is a large fleshy toadstool belonging to the class Basidiomycetes, Agaricaceae, Pleurotaceae, and the genus Pleurotus.

Problems solved by technology

The traditional Pleurotus eryngii culture medium uses a large amount of rotten crop straw to scatter the strains of Pleurotus eryngii on it. The growth of the strains is uneven and it is not easy to pick uniformly. The lack of some nutrients in Pleurotus eryngii affects the growth head, prolong the growth cycle, reduce the yield
