Method for culturing and propagating strains after inoculation of mulberry branches and strain culturing and propagating device

Abstract

The invention belongs to the technical field of edible fungus cultivation, and discloses a method for culturing and propagating strains after inoculation of mulberry branches and a strain culturing and propagating device. The method comprises the following steps of selecting fresh or partially dehydrated mulberry branches, obliquely cutting the mulberry branches, soaking, wrapping, sterilizing, inoculating, inoculating to a fungus bag after hyphae are overgrown, and transferring the inoculated fungus bag to an environment suitable for the growth of the hyphae for culturing. Local materials areused, and remarkable ecological benefits and economic benefits are achieved. The mulberry branches are main by-products of mulberry planting and silkworm breeding, the area of a mulberry field is 1410000 mu, 700000 tons of mulberry branches are produced every year, farmers usually stack the mulberry branches in the field for incineration, the income of the farmers can be increased, and the ecological environment is protected. By using the mulberry branches for inoculation, the propagation cost is reduced by 50%, and the working hours are saved by two times. The method has the advantages of high strain propagation speed, low culture cost, high survival rate, easiness in fungus bag insertion, no damage to hyphae and the like. The inoculated fungus bag is convenient to transport.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a method and a propagation device for cultivating and propagating strains after inoculation with mulberry branches. Background technique [0002] At present, edible fungus branch strains use non-aromatic wood and wheat bran that are not very hard to produce edible fungus strains as a medium. Germination is fast, which can significantly shorten the culture time of the bacteria bag, thereby reducing the pollution rate. [0003] Through the above analysis, the problems and defects in the prior art are: [0004] (1) It is inconvenient to obtain materials locally in the prior art, and it needs to be processed into a suitable size, which is time-consuming and labor-intensive. [0005] (2) The main disadvantages of the processed branch culture strains in the prior art are that there are few nutrients, and the growth of mycelium is weak in the later stage ...

AI Technical Summary

Problems solved by technology

[0004] (1) It is inconvenient to obtain local materials in the existing technology, and it needs to be processed into a suitable size, which is time-consuming and laborious

[0005] (2) The main disadvantages of the processed branch culture strains in the prior art are that there are few nutrients, and the growth of mycelia in the late stage of germination is weak. When inoculating, the survival rate is difficult to reach expectations, and the probability of contamination is high.

[0006] (3) The culture time of the bacteria itself is too long

Due to these factors, branch strains have not been popularized on a large scale
