preparation example Construction

[0033] A preparation method of a mushroom cultivation substrate containing walnut pruning sawdust, comprising the following steps:

[0034] a. Use a pulverizer to crush miscellaneous wood chips and walnut prunings into granules. According to the addition ratio of miscellaneous wood chips and walnut pruning sawdust, weigh the two kinds of sawdust and pile them up separately. The sawdust is drenched, and then covered with plastic film for 18 to 24 hours to make the miscellaneous sawdust and walnut pruned sawdust fully soaked; the next day, turn the pile again until it is soaked, and mix the walnut pruned sawdust and miscellaneous sawdust. Add the corresponding amount of bran and gypsum and mix and stir for 15-25 minutes;

[0035] b. During mixing and stirring, add water until the water content reaches 60-75%, pack the mixture into bags, sterilize at 121°C for 2-4 hours, and transport it when the temperature of the bacteria bag is at 50-60°C Put it into an inoculation environmen...

Embodiment 1

[0043] 60 parts of sawdust, 21 parts of walnut pruning sawdust, 18 parts of bran, and 1 part of gypsum.

Embodiment 2

[0045] 40 parts of sawdust, 41 parts of walnut pruning sawdust, 18 parts of bran, and 1 part of gypsum.

Abstract

The invention belongs to the technical field of edible fungus culture, and particularly relates to a shii-take culture medium containing wood dust from walnut cut branches and a preparation method ofthe shii-take culture medium. The shii-take culture medium is prepared from, by weight, 0-80 parts of miscellaneous tree dust, 1-81 parts of the wood dust from the walnut cut branches, 18 parts of bran and 1 part of gypsum. By means of the shii-take culture medium, the content of proteins, polysaccharides, crude fibers and amino acids in shii-take can be increased, the nutrient content of the shii-take is increased, the growth speed of shii-take mycelia is increased, the bag filling time is shortened, fruiting is early, more weight of each piece of shii-take is increased, and the benefits aregood. The problem that broadleaf wood dust is high in cost to result in that the culture cost continues to be increased can be solved, and resource utilization of the waste wood dust from the walnut cut branches can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a mushroom cultivation substrate containing walnut pruning sawdust and a preparation method thereof, which can promote the growth of mushrooms and increase the nutrient content of fruit bodies. Background technique [0002] Lentinus edodes is a kind of wood-rot fungus, also known as shiitake mushroom and winter mushroom. Because of its rich nutrition, it is known as the "Queen of Fungi" and is the second largest edible fungus in the world. Ergosterol in shiitake mushrooms can effectively prevent and treat rickets, and lentinan can enhance cellular immunity. It is an edible fungus with rich nutrition and high medicinal value. [0003] With the rapid development of the economy and the strengthening of people's awareness of health care, more and more people pay more and more attention to the nutritional and medicinal value of shiitake mushrooms, which g...
