Method for preparing pleurotus eryngii culture medium

Abstract

The invention discloses a method for preparing a pleurotus eryngii culture medium. The pleurotus eryngii culture medium comprises the following components: 3-5% of wheat bran, 0.05-0.1% of peptone, 2% of cane sugar, 0.05% of MgSO4.7H2O, 0.1% of KH2PO4 and 92.75-94.8% of water. The method for preparing the culture medium comprises the following steps: firstly, adding a proper amount of water into a container, subsequently boiling the wheat bran in water to obtain decoction in a liquid state, weighing, adding into water, adding a proper amount of peptone, cane sugar, MgSO4.7H2O and KH2PO4 into the water according to the amount of the wheat bran decoction, subsequently heating the container, stirring to smelt solid substances in the container, finally replenishing the water to be an expected amount, subsequently adjusting the pH value, sealing and packaging. By adopting the method for preparing the pleurotus eryngii culture medium, the culture efficiency of pleurotus eryngii is improved, the difficulty and the risk in culture are alleviated, the season limit is well avoided, the investment is saved, and the economic benefits are improved.

Description

Technical field [0001] The invention relates to a culture medium, in particular to a culture medium capable of rapid fermentation of Pleurotus eryngii. Background technique [0002] Pleurotus eryngii, also known as Pleurotus eryngii, has thick flesh, crisp texture, complete main nutrients, high protein, cellulose, polysaccharide and mineral content, and low fat content. It can lower blood pressure, lower blood fat, and prevent Tumor, enhancement of body immunity and other functions, it is a new species of rare edible fungus that has been successfully developed and cultivated in recent years, integrating food, medicine and diet therapy. Pleurotus eryngii is a low-temperature type fungus, the temperature is higher than 20 ℃, the mushroom stalk is easy to shrink and yellow, or even rot, and is susceptible to bacterial infection. The scale of commercial cultivation is small, the biological conversion rate is low, and its cultivation is difficult. Larger, the required input cost is h...

AI Technical Summary

Problems solved by technology

Pleurotus eryngii is a low-temperature fungus. When the temperature is higher than 20°C, the stalk is easy to shrink and turn yellow, or even rot. It is easy to be infected by bacteria. The scale of commercial cultivation is small, and the biological conversion rate is low. It is difficult to cultivate. Larger, the required input cost is higher, and it is easy to be affected by the outside world during the cultivation process to cause production accidents, which affects the output of Pleurotus eryngii, thus greatly increasing the difficulty of cultivation
