Cultivation techniques of Lentinus edodes
The culture material cultivation of Lentinus edodes, also known as substitute cultivation, is another cultivation method after Linden or log cultivation. Its cultivation forms are various, mainly designed according to different culture conditions, culture materials and culture containers. It has developed rapidly in recent years, accounting for more than 95% of the cultivated area. According to different cultivation methods, it can be divided into block cultivation and bag cultivation, and according to different cultivation places, it can be divided into mushroom room cultivation, underground engineering cultivation, greenhouse cultivation, sunny border cultivation, woodland cultivation and so on.
1. Material selection and processing
The main results are as follows: (1) sawdust is mainly hard hardleaved wood, which can be made of sawdust produced by wood mills or branches of trees. Collecting sawdust is often mixed with pine, fir, camphor and other sawdust, which should be piled up and fermented before use in order to obtain high yield.
(2) Straw
Cotton stalk: after drying and crushing, it contains crude protein 4.9%, crude fat 0.7%, crude fiber 41.4%, soluble carbohydrate 36.6%, crude ash 3.8%, calcium 0.07%, phosphorus 0.01%, general water 12.52%. It is appropriate to add 1% lime accumulation fermentation before use and wash it with clean water.
Bagasse: fresh, dried white or yellowish white, with sugar aroma. Do not fully dry, caking, blackening, musty smell can not be used, the coarse residue with skin should be crushed and screened. Due to the low lignin in bagasse, it is appropriate to add 30% sawdust when using bagasse as the main material.

Necessary conditions for the growth and development of Lentinus edodes
1. Nutritious Lentinus edodes is a kind of higher wood rot fungus. The carbon source for its growth comes from lignin, cellulose, nitrogen source and inorganic salt, and is taken from wood bark or wheat bran (rice bran) added to sawdust medium. After Lentinus edodes was inoculated into Lentinus edodes, the culture material was decomposed into small molecular substances which could be absorbed and utilized by the mycelium of Lentinus edodes, and the mycelium biomass increased with the increase of culture time. When the culture material was fully degraded, the mycelium of Lentinus edodes accumulated a lot of nutrients, which laid the material foundation for the occurrence of fruiting body. In the appropriate strip

Sterilization and inoculation of Lentinus edodes
Lentinus edodes culture medium mostly uses the method of atmospheric pressure and high temperature sterilization to achieve the purpose of killing pests. (1) bag material sterilization: put the bag in the human sterilization stove and sterilize under normal pressure. Before putting the material bag into the stove, add enough water to the steamer first. When the material bag is loaded into the stove, it should not be installed in the shape of "product". It should be discharged overlapping from top to bottom, leaving a gap between the row and the discharge to make the air flow up and down smoothly. After the bag entered the warehouse, the fire immediately burned, so that the temperature quickly rose to 100 ℃ within 6 hours and lasted for 24 hours. To achieve the goal of "head attack, tail protection,
