Preparing method of stropharia rugoso-annulata reduction strain and culture and application

Abstract

The invention discloses a preparing method of a stropharia rugoso-annulata reduction strain and culture and application. By means of the method, a traditional solid strain mode is broken through, thenew mode of preparing a liquid strain, separating the strain and a culture substrate, conveying the pure strain and adding liquid on purpose to reduce the strain is adopted, and meanwhile in cooperation with the liquid formula of the reduction strain, large-field or under-forest spraying inoculation can be conducted. In the liquid formula, 0.01-0.05% of yeast powder, 0.03-0.08% of K2HPO4, 0.03-0.08% of KH2PO4, 0.01-0.05% of MgSO4 and 0.1% of decavitamin solution are added to 1 L of distilled water, wherein the decavitamin solution is prepared by mixing 0.1% of thiamine hydrochloride and 0.01%of riboflavin and adding water. On one hand, the liquid culture seed sowing process is simple, the preparing cost is low, fungus generation is rapid, and the stropharia rugoso-annulata culture efficiency is remarkably improved; on the other hand, the separated pure strain is small in size, convenient to convey and low in heating amount, the strain is separated from the culture substrate, and the heating fungus burning in the strain conveying process is effectively avoided.

Description

technical field [0001] The invention relates to a production method and cultivation application of a reduced strain of Stropharia stropharcoides, belonging to the technical field of edible fungus seed production and cultivation. Background technique [0002] Large Stropharia ( Stropharia rugoso-annulata ), belonging to the order Agaricaceae, Strophariaceae, and the genus Stropharia. It is a new mushroom species recommended by the Food and Agriculture Organization of the United Nations (FAO) to developing countries, and it is also one of the top ten varieties in the international mushroom trading market. Its fruiting body contains a variety of essential amino acids and vitamins, and has medicinal value in preventing coronary heart disease, anti-tumor and other diseases, and is very popular among consumers. At present, in production, solid cultivars are usually used for inoculation and cultivation, which requires a large amount of solid cultivars and large differences in bact...

AI Technical Summary

Problems solved by technology

At present, in production, solid cultivars are usually used for inoculation and cultivation, which requires a large amount of solid cultivars and large differences in bacterial ages, resulting in low seeding efficiency

The more prominent problem is that the strains of Stropharia stropharii are relatively vigorous, and the mycelium of solid strains will generate a lot of heat due to the mixture of mycelium and solid substrate, resulting in the phenomenon of burning bacteria. The quality of mushroom strains and the demand for long-distance transportation
