Method for cultivating shiitake mushrooms in greenhouse
(1) management of spawning period;
The management of mycelium growth and development stage is mainly to adjust temperature, keep moisture and prevent contamination by miscellaneous bacteria. To prevent contamination by miscellaneous bacteria, the room temperature should be controlled below 15℃ within 10 days after sowing. Two days after sowing, the strain began to germinate and gradually grow around. At this time, the temperature change in the culture material should be checked several times a day, and the material temperature should be controlled below 30℃.
If the material temperature is too high, the film should be uncovered and ventilated to cool down, and then the film should be covered after the temperature drops. There is no need to tilt the film after the temperature of the material is stabilized. After 10 days, hyphae grow all over the material surface and enter the material layer. Can you raise the room temperature to 20 at this time? 25 ℃。 If contamination by miscellaneous bacteria is found, it can be sprinkled with lime powder or wiped with 0.3% carbendazim. During this period, the relative humidity of the air will remain at about 65%. In general, after sowing, 20? After 30 days, the mycelium will grow full of culture medium.
(2) Result period management:
After the mycelium is full of culture material, open the doors and windows of the mushroom house and the plastic film 1 hour at the lowest temperature every day, and then cover it, which can increase the temperature difference between the material surfaces and promote the formation of fruiting bodies. It is also necessary to spray water according to humidity to adjust the relative humidity of indoor air to above 80%. When the mycelium reaches physiological maturity and meets suitable temperature, humidity, air and light, it will twist into many gray millet-like bacterial buds.
At this time, it can be sprayed into the space to keep the relative humidity of indoor air at about 85%. Do not spray water on the surface of the material to avoid affecting the development of mushroom buds and causing the death of young mushrooms. At the same time, plastic film should be set, which is both ventilated and humid, and the indoor temperature can be kept at 15? 18℃。
After the bacterial bud pile is formed, it grows rapidly, 2? After 3 days, when the stem is elongated and the original gray-black or brown oblate cap is formed at the top, the plastic film can be removed and a small amount of water can be sprayed on the surface of the material to keep the relative humidity of indoor air at about 90%. Usually spray 2 a day? For three times, the temperature was kept at about 65438 05℃.
Cultivation techniques of Lentinus edodes in greenhouse
First, the management of water spraying depends on the surface moisture of the bacteria stick to prevent mildew. Spray water when the skin of the fungus stick is slightly dry, and the humidity should not be too high to avoid mildew. Generally, after picking mushrooms in the morning, spray water and then ventilate in time. Be careful not to spray on rainy days, before picking, or when the fungus sticks are wet.
Second, the ventilation of mushroom shed should be flexible to prevent hypoxia. Fresh air is supplemented by combining mushroom picking and blowing every day. When the temperature is higher than 20℃, open the shed film and the tuyere of the back wall for ventilation, and open it all in sultry days and rainy days. When the temperature is higher than 25℃, uncover the shed film and ventilate it 2-3 times a day for about 30 minutes each time.
Third, the temperature difference stimulus should be moderate to prevent out of control. After the hyphae rejuvenate after each harvest, the heat preservation cover is tightly covered during the day and lifted at night to form a temperature difference of 65438 00℃, which promotes the mushroom bud to occur for 3-4 days. If the temperature difference stimulation is improper, it will affect the fruiting.
Fourth, mold cleaning should be timely to prevent pollution. After picking a batch of mushrooms, remove the parts with mold on the mushroom sticks with a knife and treat them centrally to prevent pollution. Arrange the processed mushroom sticks on the mushroom bed, let them ventilate, slightly dry and humidify.
Five, rod water injection should be appropriate, to prevent excessive. Water injection with fungus sticks is the key link of spring management. But not too much, lest cause mildew.
Sixth, pick mushrooms in time to prevent opening umbrellas.
Construction method of mushroom greenhouse
1, ventilation and dehumidification. Ventilation is a good way to reduce humidity. Ventilation must be carried out at high temperature, otherwise the indoor temperature of multi-span greenhouse will drop. If the temperature drops too fast during ventilation, close the vent in time to prevent vegetables from being hurt by the sudden drop in temperature.
2. Plastic film mulching. Plastic film mulching can reduce the evaporation of soil moisture and is an important measure to reduce indoor air humidity.
3. Increase the temperature and reduce the humidity. This method can not only meet the demand of vegetables for temperature, but also reduce the relative humidity of air. When the plants grow to be resistant, water and close the shed to raise the temperature to about 30℃ 1 hour, and then ventilate and dehumidify. After 3-4 hours, when the greenhouse temperature is lower than 25℃, it can be repeated 1 time.
4. Use thermal insulation curtain materials with good hygroscopicity. Non-woven fabric and other thermal insulation curtain materials with good moisture permeability and hygroscopicity can prevent dew condensation on the inner surface of the shed and prevent dew from falling on plants, thus reducing the air humidity of multi-span greenhouses.
5. Natural moisture absorption. Materials such as straw, wheat straw and quicklime can be laid between rows to absorb water vapor or fog and achieve the purpose of reducing humidity.
