Bag cultivation method for inserting tube into middle of shiitake mushroom short bag for inoculating ripe materials

Abstract

The invention belongs to the technical field of bacterium cultivation, and discloses a bag cultivation method for inserting a tube into the middle of a shiitake mushroom short bag for inoculating ripematerials. A bag body and a hollow tube are arranged; the bag body is filled with culture materials, a circular hole is formed in the middle of the culture materials, one end of the hollow tube is filled with cotton, the hollow tube is inserted into the circular hole of the bag body, and the end filled with the cotton faces upwards. Accordingly, by punching the middle of the material bag and inserting the tube, in the sterilization process, high pressure steam penetrates through the material bag conveniently, the disinfection and sterilization time is short, sterilization is conducted thoroughly easily, the infection rate is lowered, bacteria inoculated in the middle make contact with the center of the bag materials, heat preservation and moisture retention are achieved, the cotton is good in air permeability, growth oxygen supply is facilitated, the bacteria germinate rapidly, spawn runing is good, and spread and growth in the materials are rapid; the sterilized cotton blocks miscellaneous bacteria invasive infection, and culture period pollution is reduced. For intermediate inoculation, compared with single end short bag inoculation and long bag peripheral punching or nail inoculation, the hypha bagfull time is shortened, long bag overgrowing time needs 60-90 d, and overgrowing of short bag intermediate inoculation only needs 25-30 d.

Description

technical field [0001] The invention belongs to the technical field of strain cultivation, and in particular relates to a clinker bag cultivation inoculated with a tube inserted in the middle of a short shiitake mushroom bag. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: Lentinus edodes is a famous edible fungus in the world. It is a traditional export commodity and native mountain delicacy in my country, with high economic value. As a food, it is not only nutritious, delicious and fragrant, but also delicate and tender, just like shredded chicken. What attracts people's attention more is that shiitake mushrooms have health care and medicinal value. With the development of modern biochemistry and medicine, the medicinal value of shiitake mushrooms has been continuously discovered and scientifically verified. Therefore, the large-scale cultivation of shiitake mushrooms is becoming more and more common. Th...

Problems solved by technology

When inoculating, commonly used are single-end short bag inoculation and long bag peripheral punching or nail seed inoculation, but these methods generally have the problem of long time for mycelium to fill the bag

[0003] During the sterilization process of the single-end short bag and the long bag, the high-temperature steam at the bag mouth cannot penetrate smoothly, which affects the sterilization effect of the bacteria bag and causes incomplete sterilization and infection of miscellaneous bacteria; the single-end short bag is inoculated and the long bag is perforated Or nail seed inoculation, mycelium overwhelms the surface of the material or the inoculation hole extends downward and to the surrounding growth process, mycelium blockage causes poor air permeability, insufficient oxygen supply, mycelium grows slowly or stops growing, such as loose bag mouth or Holes are perforated for ventilation, and it is easy to cause bacterial contamination in the later stage; when the peripheral of the long bag is perforated or inoculated with nails, the bacteria are exposed, and are susceptible to germination and bacterial infection affected by the dry and wet environment. For example, bagging protection not only increases the workload but also affects the breathable oxygen

[0004] In summary, the problems in the prior art are: The existing shiitake mushroom inoculation mycelia full bag time is longer

Single-end short bag and long bag, the poor high-temperature steam permeability of the bag during sterilization affects the sterilization effect, and it is easy to cause late pollution during the mycelium cultivation process; single-end short bag inoculation and long bag peripheral punching or nail seed inoculation, the material The bag has poor air permeability and insufficient oxygen supply. It takes a long time to fill the bag with shiitake mushroom inoculation mycelium
