First, how many stubbles of mushrooms are planted in greenhouse a year
The growth period of Lentinus edodes in greenhouse is relatively long, which usually takes 5-6 months or even longer. Generally, Lentinus edodes are only planted once a year. If the varieties with short post-ripening period are adopted and the climate is suitable, two crops can be planted.
When planting, it should be noted that if the material temperature is too high, the film must be opened in time, ventilated and cooled, and then covered with film after the temperature drops. Under normal circumstances, hyphae will grow all over the culture material 20-30 days after sowing.
Second, the suitable planting temperature of Lentinus edodes in greenhouse
The suitable planting temperature of Lentinus edodes in greenhouse is 22-27℃. The hyphae below 10℃ and above 30℃ grew poorly. In addition, the temperature range of fruiting body development is 5-25℃. Different strains of Lentinus edodes require different temperatures for fruiting body differentiation, so attention should be paid to the introduction and cultivation.
Third, the management method of mushroom fungus growth period
(1) In order to prevent contamination by miscellaneous bacteria, the room temperature should be controlled below 15℃ within 10 days after sowing. When the strain begins to germinate and gradually grow around, check the temperature change in the culture material several times a day to control the material temperature below 30℃.
(2) If the material temperature is too high, the film should be uncovered, ventilated and cooled, and then the film should be covered after the temperature drops. When hyphae grow all over the material surface and grow into the material layer, the room temperature can be raised to 20-25℃, and the relative humidity of air can be kept at about 65%. Under normal circumstances, hyphae will cover the whole culture material 20-30 days after sowing.
Four, the main points of management of mushrooms in the fruiting period
(1) After the mycelium is full of culture materials, open the doors and windows of the mushroom house and the plastic film at the lowest temperature every day 1 hour, and then cover it, which can increase the temperature difference between the material surfaces and promote the formation of fruiting bodies.
(2) Spray water according to the humidity, so that the relative humidity of indoor air can be adjusted to above 80%. When the mycelium reaches physiological maturity and meets suitable temperature, humidity, air and light, it will twist into a lot of gray-white 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 material surface, so as not to affect the development of mushroom buds and cause the death of young mushrooms.
(3) 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 treated mushroom sticks on the mushroom bed, let them ventilate, dry slightly and humidify. Do not inject too much water into the fungus stick, so as not to cause mold rot.
5. What should I do if the mushrooms in the greenhouse are soft for the second time?
1, after the mushrooms are released for the second time in the greenhouse, the mushroom sticks are soft, and the mushroom cultivation period is about 15 days. During this period, the temperature in the greenhouse must be controlled at 20-23℃, and the temperature in the greenhouse during the mushroom cultivation period should be constant to avoid temperature difference stimulation.
Don't pour water on the mushroom sticks during the cultivation. You can water the ground to keep the humidity in the shed at about 65%. If the mushroom sticks are dry, you can spray some water on them, and pay attention to ventilation when watering.
2. During the period of cultivating bacteria, we must strengthen the ventilation management to keep the air in the shed fresh. Generally, we should ventilate twice a day/kloc-0, and ventilate for about 30-60 minutes each time.
You can spray sterilization drugs or sprinkle quicklime on the ground for disinfection three days before mushroom cultivation, and you must clean up the mushroom feet and stalks left on the mushroom sticks in time to do a good job of environmental protection for the next mushroom production.
3. The management of mycelium growth and development stage is mainly to regulate temperature, keep moisture and prevent contamination by miscellaneous bacteria.
In order to prevent the mycelium from being polluted by miscellaneous bacteria, the room temperature must be controlled below 15℃ within 10 days after sowing. After 2 days of sowing, the strain will start to germinate and gradually grow around. At this time, the temperature change in the culture material should be checked every day, and the temperature must be controlled below 30℃.
4. After picking 1 batch of mushrooms, you can use a knife to remove the parts with mold on the mushroom stick, and you must carry out centralized treatment to prevent pollution.
Arrange the treated mushroom sticks on the mushroom bed, let them ventilate, slightly dry and humidify, and the water injection into the mushroom sticks must not be excessive, so as not to cause mold rot.
