Mushroom culture medium and preparation method thereof

Abstract

The invention belongs to the technical field of fungus cultivation, and particularly relates to a mushroom culture medium and a preparation method thereof. The mushroom culture medium is composed of the following raw materials by weight: 35-40 parts of vernicia fordii sawdust, 15-25 parts of corn cob, 8 to 12 parts of bran, 8 to 12 parts of beet pulp, 0.5 to 2.5 parts of wormwood, 1.5 to 3 parts of astragalus, 1.5 to 2.5 parts of sophora flavescens, 8 to 12 parts of shell powder, 6 to 10 parts of lotus leaf powder, 1 to 3 parts of potassium sorbate and 55 to 65 parts of water. The preparationmethod of the mushroom culture medium consists of the following steps: (1) pulverizing the vernicia fordii sawdust, corn cob, bran, beet pulp, wormwood, astragalus, and sophora flavescens; (2) addingthe shell powder, lotus leaf powder and potassium sorbate to the pulverized raw materials; (3) mixing uniformly with water; (4) performing high temperature steam sterilization after packaging; and (5)make vents in a packing strap. The culture medium of the invention can provide a good nutrient and space environment for the growth of the mushroom, accelerate the growth rate of the mushroom hyphaeand increase the biomass of the hyphae, the growth of the mushroom hyphae is good, and the preparation method is simple.

Description

technical field [0001] The invention belongs to the technical field of mushroom cultivation, and in particular relates to a mushroom culture medium and a preparation method thereof. Background technique [0002] Shiitake mushroom, also known as Xiangxin and Huagu, is known as the "Queen of Mushrooms" and has always been loved by consumers. As a common edible fungus, shiitake mushrooms have high nutritional value. At the same time, shiitake mushrooms are also well-known medicinal fungi, which have the effects of improving immunity, anti-tumor, anti-virus, and lowering cholesterol. Mycelium is the vegetative growth stage of shiitake mushrooms, and it is the prerequisite for obtaining high-quality shiitake mushroom fruiting bodies, and a good medium is the basis for obtaining robust shiitake mushroom mycelium. [0003] The current methods of growing shiitake mushrooms mainly include basswood cultivation and bag material cultivation, while section wood cultivation requires a l...

Problems solved by technology

[0004] The existing medium for mushrooms is mainly composed of sawdust, cottonseed hulls, corncobs and other crop straws and animal manure, which mainly has problems such as unbalanced nutrients in the medium, low utilization rate of nutrients for mushrooms, and slow growth rate.

[0005] The Chinese invention with the publication number CN107698294A discloses a culture medium for mushrooms and its preparation method. Although the invention improves the utilization rate of nutrients of mushrooms, the required raw materials are complicated and have no effect on the growth rate of mushrooms.
