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 are selected, such as "Xiang VED" and so on.

two。 The formula of culture material is 78% hard sawdust, 20% wheat bran, 1% gypsum and 1% sugar, and 0.1% magnesium sulfate.

3. After high temperature sterilization, fill the steamer with water, spread a layer of gunny bags on the curtain to avoid leakage, spread the culture material 8cm to 10cm thick on the curtain, and spread the material layer by layer with a shovel when the steam comes up. Pay attention to the material surface, where there is steam, and where to spread the material. Until 20 cm from the top. Press the cover tightly, put the air on the top layer, sterilize for 4 hours and 6 hours, then cool out of the pot and wait for the block.

4. Block inoculation to break the bacteria into pieces, evenly mixed in the culture material, and then spread a layer of bacteria on the surface. The size of the block is 37 cm in diameter and 10 cm thick. The bacteria are raised on the shelf after pressing.

5. The culture of bacterial mass can be divided into three stages. After 10 days, the temperature was raised to 5: 12 ℃, and the hyphae could be covered after 20 days. The mycelium can be full of culture material in 40 days. The third stage is the color conversion period of 40-60 days, that is, the color conversion stage, after the mycelia grow full, appropriate ventilation and increase scattered light to promote color conversion; timely elimination of yellow water when spitting yellow water to prevent rotten pieces.

6. After the mushroom management fungus completely changes color, it enters the mushroom management. Open the film of the fungus during the day to make it come into contact with the air, rewrap it at night, increase ventilation and increase the temperature difference between day and night. After 2-3 days of treatment, the fungus went into the mushroom stage. The temperature of mushroom production is controlled at 15-22 ℃, and the air relative humidity is kept at about 90%. Pick fresh mushrooms in time, raise bacteria after the first tide of mushrooms for about 20 days, and then soak or spray water into the management of the second tide of mushrooms.
