The production technology of bag-grown mushrooms
One, make bacteria bag 1. The use of granular sawdust and ordinary sawdust not only have poor ventilation, but also the grown strains are easy to shrink and age, and the application period is short. Switching to the granular sawdust special for mushrooms not only has good air permeability, but also grows bacteria quickly. In addition, the pellet sawdust has the similar characteristics of the branch strain, the mycelium breaks and damages less during the inoculation, the germination is fast, and the survival rate is high. The mycelium in the pellets of sawdust blocks grows slowly. After being full, part of the hypha in the sawdust particles is still "feeding", and the strains are not easy to shrink and age, and the service life is long. 2. To reduce the water content of the culture medium, granular wood chips are used, and the ratio of dry material to water is about 1:0.85, and the quality of cultivated strains is greatly improved. 3. When bagging, sterilizing, and bagging, leave about 8 cm at the mouth of the bag. After filling, use a hardwood stick with a diameter of 2 cm and a blunt tip at one end to pierce a hole about 4 cm deep in the middle of the bag mouth. Tightly insert the membrane into the middle tie, and then forcefully re-insert the wooden stick into the bottom of the bag mouth. Tighten a circle of cotton between the bag mouth material membrane and the wooden stick with a tweezers handle to prevent infection of germs before inoculation. Sterilize with wooden stick mounted stove. 2. Vaccination Take out the tampon at the mouth of the bag in the sterile box, pull out the wooden stick, use sterile tweezers to grab the lumpy strain and push it into the hole of the bag mouth to the bottom, and fill it up to the place near the mouth of the bag, then use the sterilized For cotton, close the bag tightly after overheating. This strain production process, 1 kg of bacteria bag, can be full in the past 30 days, the hyphae are thick and thick, the strain is tough and not easy to loose. Since the strain is inserted into the central hole in the bag, it grows from inside to outside, and the two ends grow evenly, which avoids the deficiency that one end is not overgrown and the other end is aging, and the strain is not easy to age, and the pot life is prolonged. In addition, the survival rate of inoculation is high and the germination is fast. The mycelium grows in aeration and aerobic, and the bacterial bag self-generates heat quickly. It is especially suitable for the production of larger seed bags in winter. Generally, it can maintain its required temperature after 10 days. Although the amount of the original species is slightly larger, the quality of the strain has been greatly improved. Three, matters needing attention In this method, because the bag is not tied, the number of stacking layers should be reduced to prevent the backlog from spreading. The sterilization basket is used to sterilize the bag to reduce the backlog. After sterilization, the bag should be discharged while it is hot to prevent the cooling water from flowing into the bag mouth and penetrating into the material. After being out of the pot, the bag should be soft before cooling and hardening. Care should be taken to touch the wooden stick to prevent the stick from loosening and invading bacteria. Since the mouth is not tied and there is no loop, the tampon should be properly tightened and deep. Disclaimer: Some articles on this website are transferred from the Internet.
