A kind of preparation method of mushroom and black fungus mold strain

Abstract

The invention discloses a method for making mold strains of shiitake mushrooms and black fungus, which comprises the following steps: making a strain mold, the strain mold adopts a nearly conical structure, including a circular bottom edge and a cylindrical The head and bottom are equipped with 3 to 9 arc-shaped flat and long strip-shaped ribs, which are gathered in the cylindrical head according to a certain arc to form a nearly conical hollow mold; Take the coarse wood chips, fine wood chips, wheat bran, corn flour, and gypsum powder, add water and mix well, then mix well with the wheat grains soaked in water and boil until there is no white heart, add a certain amount of bacteria to mold, mix well, and put The molds filled with culture material are picked out; according to the number of molds picked out, the culture material is added as the filling material between the molds, bagged, sterilized, cooled and inoculated. The strains obtained by the invention have the advantages of fast and uniform separation of strains, no need of punching holes, high efficiency of inoculation, low pollution rate and the like.

Description

technical field [0001] The invention relates to the production technology of edible fungus strains, in particular to a method for making molded strains of shiitake mushrooms and black fungus. Background technique [0002] Lentinus edodes and black fungus are the two largest edible fungi industries in my country, with an annual output of 15 million tons of fresh fungus. The production mode of mushroom and black fungus in the main production area in the south has the mushroom stick type. The strains currently used are mainly sawdust strains, which need to be punched, separated, and plugged during inoculation. Sawdust strains are often separated at a slow speed and uneven in size, which affects the efficiency and effect of inoculation. It is conducive to intensive and large-scale production, and the black fungus is made of sawdust bacteria, and the fingers are squeezed during inoculation, which is easy to damage the bacteria and affect the survival rate. The other kind of str...

The strains currently used are mainly sawdust strains, which need to be punched, separated, and plugged during inoculation. Sawdust strains are often separated at a slow speed and uneven in size, which affects the efficiency and effect of inoculation. It is conducive to intensive and large-scale production, and the black fungus is made of sawdust bacteria, and the fingers are squeezed during inoculation, which is easy to damage the bacteria and affect the survival rate

The other kind of strain is capsule strain, with the same specifications, which overcomes the slow and uneven division of traditional wood chip strains, and the inoculation speed is higher than that of wood chip strains, but the shortcomings are also obvious. First, the capsules are smaller. The amount of species is small, not resistant to storage, and the shelf life is short; the second is that the production of capsule strains requires specialized equipment, which requires large investment and high cost, and is not suitable for general bases and large households to self-produce, and the price of purchasing capsule strains is higher per rod The cost of the seed is more than 0.1 yuan. Third, the culture of the strain is crushed and then pressed into capsules, which has the potential for secondary infection. Currently, it is only limited to a small amount of promotion in some areas.

For more than ten years, there have been 3 types of bacterial molds with different shapes. After collecting and testing, it was found that there were several defects, which led to no application in production so far.

One is that the tip part of the mold is quite sharp, which is easy to hurt hands when bottled and bagged, and easy to pierce the bag when making seeds; second, the structural size of the mold is unreasonable, especially the mold area of ​​the column and the tip is large, which affects the introduction of bacteria The contact area between the material rod and the material rod is slow to produce bacteria, which affects the survival rate of inoculation

Third, the structure and size of the mold are unreasonable, resulting in high costs for the mold and the application of the mold strain, which does not have a competitive advantage
