Management techniques of Lentinus edodes planted in the ground

L, build a shed: according to the number of planting, build a bacterial shed, generally covering an area of 120 square meters per 10,000 bags, the brightness in the shed can not be too large, otherwise it will affect the normal growth of hyphae.

2. Material preparation: calculated in 10,000 bags, 11 tons of wet sawdust, 3 cubic meters of fine broadleaf sawdust, 2 tons of wheat bran, 100 kg of sugar, 100 kg of gypsum and other materials must be prepared for use.

3. Bagging: ① stirs the coarse sawdust, wheat bran and gypsum well, melts the sugar and adds it to the water. Sprinkle water evenly over the mixture. The amount of water depends on the dryness and wetness of sawdust. It is appropriate to make the moisture content reach 65% / 70%. ② put the material into a 53cm × 15.2cm bacterial bag. The weight of the bacterial bag is 1.8le 1.9kg. The upper and lower parts of the bag are loose and tight. If the bag is too tight, it is easy to produce a supporting bag. Too loose will affect its output and the bag is easy to break.

4. Sterilization: it is usually sterilized under atmospheric pressure, and it is appropriate to pack 3000ml 3500 bags in each pot. Steam the bag up to 100℃ and steam for 20 hours to eliminate harmful bacteria in the material.

5. Inoculation: lower the temperature to below 25 ℃ in an airtight way, and then fumigate the sterilized bags for 5 hours. After that, hit 4 holes on the front of each bag, fill it with fungus and stick it firmly with adhesive tape.

6. Germ: after recovering the bacteria bag at room temperature for 2 days, raise the temperature to 18 ℃ and keep the bacteria room clean. When the bacteria grow to 10 cm, the bacteria will be pierced to release oxygen, and the original 4 will be piled together into 3, so that the air can fully enter the stack. When the bacteria grew to the back, the second oxygen release was carried out, and the number of piercing holes was 18-22. In the later stage of the inoculation process, the bacterial bag produces heat by itself, and the temperature should be below 28 ℃.

7. Under the ground: in June, take off the outer bag of the bacteria bag, go down to the small arch shed that has been built, and fill the seams of each bag with fine sand. At the same time, we should use micro-spray or artificial water spray, so that the bacterial bag can not lose water, according to the weather conditions, spray water 4 times a day. The density of the shading net out of the mushroom shed should be more than 90%.

8. Mushroom production management: after spraying water for 5 days, the small mushroom buds will grow up, and the overdense and deformed mushroom buds should be removed. With the growth of mushroom buds, the amount of water spraying should be gradually reduced, otherwise it will affect the quality of mushrooms. Do not go out of the shed for more than 25 ℃. Pick mushrooms according to the quality of the mushrooms, at least 3 times a day.

9, the management after the second stubble mushroom: with the reduction of the number of mushrooms, increase the number of water spraying to replenish water, so that the water is fully replenished, and the bacteria are resting. After the bacteria rest, vibrate the stick with rubber or soft foam to stimulate mushroom production. With the number of mushrooms, the stick will shrink, there will be cracks between the sticks, it is necessary to wipe out the cracks with fine sand in time.
