Method for making tertiary strain matrix and strain bag of shiitake mushrooms using raw materials of branches

Abstract

The invention relates to a method for producing a three-level mushroom strain matrix and a strain pocket by utilizing raw materials of withe cut logs. The strain matrix comprises the following components: 60 to 5000 portions of withe cut logs, 30 to 2500 portions of sediments, 10 to 850 portions of wheat bran, 1 to 100 portions of pulverized lime, 1 to 100 portions of gypsum powder, 0.3 to 25 portions of urea and 2 to 170 portions of calcium superphosphate. The method effectively solves the problems of thick granules of withe cut logs, low retention rate as a result of big clearance of the matrix, less hyphae in the matrix, easy aging of strain and the like. Compared with the strain of the matrix of simple cut logs, the use level of the cut logs is reduced by more than 30 percent, and the use level of the wheat bran is reduced by 50 percent; and compared with the strain of the matrix of sawdust, the contamination is reduced by about 80 percent. After being used in the strain pocket inoculation, the mushroom hyphae obviously become burlier, denser and thicker and grow radially, the spawn running can be completed ahead of 7 days, and the storage period is prolonged by more than 40 days.

Description

technical field [0001] The invention relates to a method for utilizing biogas residue raw materials, in particular to a method for making third-grade mushroom strains of shiitake mushrooms by cutting common branch raw materials and combining them with biogas residues, which belongs to the method of using new resources and new materials to obtain the third-grade strains of shiitake mushrooms technology field. technical background [0002] Shiitake mushrooms [Lentinus edodes (Berk.) sing] is one of the traditional important export agricultural products in my country. Especially since my country's accession to WTO, the economic benefits of shiitake mushroom export have greatly stimulated the production enthusiasm of mushroom farmers. Utilization was originally regarded as The waste tree branches, wood shavings, etc. are used for the cultivation and production of shiitake mushrooms. The general input-output ratio is about 1:2. . [0003] The third-level species of shiitake mushr...

AI Technical Summary

Problems solved by technology

Previously, many seed production units and individuals had tried or tested the third-level species of branch substrates, but due to the lack of raw materials and increased costs, it was impossible to achieve large-scale and industrialized production.

For example, the classification number A01G1/04 and the application number are 99116468. The production process of long branch strains of edible fungus in bags is from the original species to the cultivated species, and then from the cultivated species to the fungus bag. Both are inoculated with long branches, and the two-stage strains are packed. Material operation and inoculation are inconvenient, and because of the inability to combine tightly between the substrates, large pores, and many aerial hyphae, the amount of mycelium in the substrate is small, and the survival rate after inoculation is low, and it is even impossible to realize the g...
