Lecture on cultivation and Management techniques of Pleurotus ostreatus

The Chinese name of slippery mushroom is bare-hat scale umbrella or smooth-cap yellow umbrella. Slippery mushroom is its common name, because its cover surface has a layer of mucus, slippery when eating, it is not easy to pick up with chopsticks, hence the name. Some provinces call it slippery mushroom. Pleurotus ostreatus is rich in nutrition, delicious and delicious, and has inhibitory effect on tumor.

Varieties and strains

Variety: according to the temperature of mushroom: very precocious species, the temperature of mushroom is about 20 ℃, the color is light brown. Precocious species, mushroom temperature about 15 ℃, brown. Medium-ripe species, mushroom temperature about 10 ℃, brown. Late mature seed, mushroom temperature below 10 ℃, dark brown or brown.

Strain: the production process of Pleurotus ostreatus refers to the production of edible fungus.

It should be noted that in the process of primary strain culture, in order to avoid the production of pollen spores, wheat bran juice culture medium should be used. Its ingredients are wheat bran (or rice bran) 50g, dipotassium hydrogen phosphate 0.3g, magnesium sulfate 0.2g, glucose 50g, peptone 5g, yeast extract 2g, Agar 20g, water 1000 ml.

Cultivation techniques

(take plate cultivation as an example) the formula of culture medium: ① sawdust 89%, wheat bran 10%, gypsum 1%. ② sawdust 49%, crop straw 40%, wheat bran 10%, gypsum 1%.

Box planting: ① sterilization: steam sterilization was used to make steam directly contact the culture medium to achieve the purpose of ripening the medium and killing miscellaneous bacteria in the culture medium. The use of this sterilization method requires "see the air to spread the material, sprinkle frequently and less". This kind of steaming material sterilization method is the same as the wine fashion retort pot, after the pot is boiled, it is sprinkled with a thin layer, and then spread the material to wherever it is gassed. In order to make the culture medium fully contact with steam, sprinkle less frequently. When the culture medium is 80% full, cover with gunny bags, straw bags and so on.
