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....

Problems solved by technology

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. In addition, the current cutting and cultivation methods of shiitake mushrooms are roughly the same. , bran, minerals, etc. into special heat-resistant plastic bags

In addition, the current compost formulations are various, some of which are too rich in nutrients, resulting in high cost but slow growth of mycelium and low yield. Nutritional imbalance causes low survival rate of strains, easy aging of mycelium, causing strain variation, affecting the growth of fungus in the later stage, and even Cause serious consequences such as the reduction of fungus production and quality decline, and the ingredients of the culture medium of most shiitake mushrooms are unscientific, the nutritional structure is unreasonable, and the nutrient content is low, resulting in low fruiting and few times of fruiting (currently, the maximum number of mushrooms is 2 to three times), the yield of the cultivated shiitake mushrooms is low and the yield is low, resulting in low economic benefits for growers
