Strain culture tube, wheat rod-like strain and preparation method of wheat rod-like strain

Abstract

The invention relates to a strain culture tube, a wheat cob strain and a preparation method thereof. The strain culture tube includes a tube body and a cap with an open upper end; the tube body includes a tube head near the open end, a tube body integrated with the tube head, and a tube tail integrated with the tube body; the side of the tube body The wall is provided with a plurality of strip-shaped through-holes; the strip-shaped through-holes are arranged in multiple rows and columns, and the distance between the strip-shaped through-holes in two adjacent rows is 1-3mm; the pipe cap is fastened to the pipe head. The rod-shaped bacteria prepared by using the strain culture tube can save the step of punching holes with an inoculation rod during inoculation, the inoculation process is simplified, the inoculation efficiency is very high, the chance of infection by miscellaneous bacteria in the inoculation process is reduced, and the yield is higher. The preparation method of the wheat cob strain provided by the invention is simple and easy to operate, the inoculation efficiency, the infection rate and the production cycle are all superior to the existing strains, and has very high practical value.

Description

technical field [0001] The invention relates to edible fungus strain cultivation technology, in particular to a strain cultivation tube, wheat cob strain and a preparation method thereof. Background technique [0002] There are mainly two kinds of existing edible fungus strains. One is cottonseed hull strains, which are formed by cultivating cottonseed hulls as medium raw materials. Cottonseed hulls can also be grains, sawdust, forage, etc., such strains Before inoculation, the strains need to be broken up into strain blocks. When inoculating, first use the inoculation stick to punch the strain pack into the reserved holes, then stuff the strain blocks into the reserved holes, and wait for the mycelia to germinate. The process of inoculation with this type of bacteria is cumbersome and the inoculation time is long. It takes 40 seconds to inoculate a bag of bacteria bags, so it is easy to be infected by miscellaneous bacteria during the inoculation process; Simultaneous grow...

AI Technical Summary

Problems solved by technology

The mycelium of the branch strains mainly grows by using auxiliary materials such as bran attached to the surface. Due to the small amount of auxiliary materials attached and the ability of the mycelia to utilize the xylem of the fungus is very weak, the mycelium activity of the branch strains is poor, so bacteria Slow, the germination cycle is long, which increases the infection rate during the germination process

In addition, in order to prevent the hyphae attached to the surface of the branches from being wiped off, it is still necessary to use the inoculation stick to punch the reserved holes in the bacterial bag, and then insert the branch strains into the reserved holes. After the mycelium germinates, the inoculation process continues More cumbersome, it takes 20s to inoculate a bag of bacteria

[0003] In summary, the existing edible fungus strains are limited by the shape or structure of the culture medium (the cottonseed shell strains are massive, and the hyphae of the branch strains are attached to the surface of the branches), resulting in cumbersome inoculation procedures and low inoculation efficiency. , long bacteria cycle, high infection rate
