The key to successful cultivation of Lentinus edodes lies in sterilization
"if the sterilization is not complete, the cultivation of mushrooms will kill people", which is the image expression of the cultivation failure caused by incomplete sterilization in the cultivation of Lentinus edodes. Sterilization is a very important link in the process of cultivating Lentinus edodes, which is related to the success or failure of cultivation.
First of all, carefully check the sterilization stove before mixing Lentinus edodes. It is necessary to check the sealing degree of the sterilization stove, the degree of flame combustion and whether the cold air is unobstructed, so as to ensure that there are no accidents in the sterilization process.
Secondly, after the end of bagging, immediately into the bag, according to the amount of 3 tons per stove, put the bag code neatly to ensure that the bag does not collapse in the process of sterilization. At the same time, add enough water to the sterilizer.
Third, at the end of the material bag entering the stove, the material pile is closed and the ignition is heated. After ignition, the fan should be adjusted to the maximum, and the method of burning should be taken. Try to raise the temperature of the bag to 100 ℃ in 4-5 hours, and then enter the holding phase. In the maintenance stage, in order to reduce the fuel cost, it is necessary to adjust the fan and adopt the method of small fire and slow burning to keep the material temperature at 100 ℃. If the material bag with a width of 15cm to 17cm is used, the time of keeping 100℃ should be not less than 16 hours; if the bag of material with a width of 24cm is used, the time of keeping 100℃ should be not less than 24 hours. In the maintenance stage, pay attention to the relationship between water and fire, when adding water to burn, to ensure that the temperature does not decrease, absolutely can not appear because of adding too much water, and the temperature in the stove is too low for a long time. After reaching the time to cease fire, the material should be stuffed for 12 hours, and the waste heat in the stove should be used to continue sterilization.

Harm and Control of Streptomyces in Lentinus edodes
Alternaria was fluffy, white or gray at the initial stage of growth, and pink and yellow at the later stage of growth. When a large number of conidia are integrated, the appearance is similar to that of hericium Erinaceus. Streptomyces is mainly caused by conidia and is the most important miscellaneous bacteria in high temperature season. The mycelium of Streptomyces is tenacious and powerful and has the characteristic of rapid propagation. once it occurs, it will be wiped out, and the result will be scrapped in batches of bacteria, culture bags or culture blocks. In order to control Alternaria, we should try our best to avoid production in high temperature season. The temperature is at the stage of Lentinus edodes growing.

Lin Baowen's cultivation experience of Lentinus edodes
Lin Baowen, Yangjiajiaolan Village, Wafangdian City, began to cultivate Lentinus edodes 9 years ago. 4800 Lentinus edodes were cultivated in an arched shed of 180 square meters, with a net benefit of more than 20, 000 yuan per year. Through his demonstration and leading role, more than 40 farmers around him have successively engaged in the production of Lentinus edodes, which is called the leader of Lentinus edodes production. His experience in cultivating Lentinus edodes is as follows. 1. The selection of strain is due to the sowing date in November, and the greenhouse temperature in the culture period and mushroom stage is greatly affected by the external air temperature. Therefore, wide-temperature varieties such as "Xiang VED" are selected.
