Method for making three-level species of Pleurotus ostreatus using Amorpha fragrans branches as matrix material

Abstract

The invention discloses a pholiota nameko three-grade seed production method taking amorpha fruticosa braches as base raw materials. The pholiota nameko three-grade seed production method comprises the following steps: obtaining branch wood sections, treating the branch wood sections, distributing wheat bran on the branch wood sections, preparing an auxiliary culture base material, forming a strain material bag, sterilizing at high pressure and inoculating. The auxiliary culture base material is prepared from the following materials in percentage by mass: 72%-85% of saw dust, 15%-25% of wheat bran, 0.5%-2% of gypsum and 0.5%-2% of lime; water is added into the materials and is uniformly mixed, and the moisture content is controlled to be about 65%. By the aid of the method for preparing pholiota nameko three-grade seeds, the fungi growth time can be shortened for 20-30 days, the inoculating speed is rapid and the pollution rate is greatly reduced; mycelia are thick and dense and grow vigorous; strains on the upper part can be prevented from being aged and the strain preservation period is prolonged by more than 30-40 days.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a method for preparing three-level varieties of Pleurotus ostreatus using Amorpha fruticosa branches as matrix materials. Background technique [0002] Slide mushroom, a kind of wood rot fungus with sticky and slippery caps that occurs in winter and spring, is one of the main artificially cultivated edible fungi. Hat scale umbrella, light hat yellow umbrella. The fruiting bodies are rich in polysaccharides, which can improve the body's immunity. Because the production of slippery mushrooms is mainly two-end inoculation and hole-punching inoculation, there are disadvantages such as high relative pollution rate, inability to plant in high-temperature seasons, and long germination time. The production quality of the third-grade strains of Pleurotus ostreatus is directly related to whether the germination period can be shortened and the biotransformation rate can ...
