Shiitake mushroom culture medium and preparation method thereof

Abstract

The invention discloses a shiitake mushroom culture medium and a preparation method thereof. The shiitake mushroom culture medium is prepared from the following raw materials including, by weight, 60-85 parts of sawdust, 10-30 parts of wheat bran, 0.5-2 parts of gypsum and 0.5-2 parts of lime. Compared with the prior art, the raw material source of the shiitake mushroom culture medium is simple, the mushroom culture medium prepared by the raw materials is rich in nutritional ingredient, after the mushroom culture medium is used for preparing mushroom sticks, the fruiting rate is high, the fruiting amount of each bag of culture medium reaches 1.8 jin to 2.1 jin, the first-grade product rate of cultured shiitake mushrooms is high, and the fruiting frequency can reach four times, so that + the shiitake mushroom culture medium is low in cost and remarkable in economic benefit.

Description

technical field

[0001] The invention relates to the technical field of edible fungus cultivation, in particular to a mushroom culture medium and a preparation method thereof. Background technique

[0002] Mushrooms are a large number of edible and medicinal varieties in various countries in the world today. The cultivation of shiitake mushrooms in our country has reached a certain scale. At present, the common culture substrate raw materials for shiitake mushrooms are cottonseed shells and wood chips. Many farmers have invested in the production of bag-grown shiitake mushrooms, and the prices of cottonseed husks and wood chips have continued to increase, resulting in higher and higher production costs for cultivated shiitake mushrooms.

[0003] Most of the shiitake mushrooms currently on the market adopt artificial cultivation techniques. Due to the strict requirements of shiitake mushrooms on external conditions such as temperature and humidity, the yield of fungus is low....

Examples

Embodiment 1

[0018] Raw materials are taken by weight percentage: 60Kg of sawdust of Chinese oak, 10Kg of wheat bran, 0.5 Kg of gypsum, and 0.5Kg of lime;

[0019] Blending and fermentation: first mix sawdust, wheat bran, and gypsum evenly, then cover with plastic film, add water at room temperature and stack for anaerobic fermentation for 5-10 days, then add lime to mix evenly, and test and adjust the pH value at the same time 6.5-7.8, the moisture content of the medium is 50-60%;

[0020] Bagging and sterilization: put the fermented medium into the culture bag and press it tightly, fill each bag with 0.6kg of medium, cover the surface with cotton or sawdust at the mouth of the bag after filling the medium, and finally put the medium Put the bag into a sterilization container, first sterilize at 105-110°C under normal pressure for 8-12 hours, then sterilize at a pressure of 0.11-0.15Mpa and a temperature of 90-95°C for 3 hours, and the sterilization is complete Then seal the medium bag t...
