Tips on the cultivation of Edible Fungi

? I. site selection

Should stay away from livestock and poultry farms, garbage dumps, chemical plants and places with a large flow of people, and require convenient transportation, adequate water and clean and pollution-free.

? II. Cultivation and management

1. Select the strain. The suitable cultivation species and varieties should be selected according to the local climatic characteristics, and the bacteria with aging or pollution should not be used, and the bacteria with strong, high quality and disease resistance should be selected.

two。 Fine management. Pay attention to the hygiene of raw materials, bags and tools. The waste should not be piled near the cultivation room and should be treated with high temperature composting before use. The new and old bacterial bags in the cultivation room must be separated and stored separately and must not be mixed, so as to achieve strict sterilization and disinfection to prevent inoculation infection and various secondary infections.

3. Scientific cultivation of bacteria. For different kinds of edible fungi, according to the requirements of their growth and development conditions, the temperature, humidity, light and pH value of the culture room should be scientifically regulated, and proper ventilation should be given to promote the robust growth of hyphae and prevent the adverse environment of high temperature and humidity.

4. Fertilize. Spraying peptone and yeast extract solution can thicken the mushroom body and promote the change of tide; spray rotten acquaintance feces and urine, and spray clear water again after spraying; spray rice vinegar. In the middle and later stages of Pingru growth, mushroom noodles were sprayed with 300 times edible rice vinegar, once a day for 3 days before harvest, the yield was generally increased by 6%, and the color was whiter; spraying culture material extract could prolong the peak period of mushroom production and thicken the fruiting body; spraying glucose and calcium carbonate solution could promote mycelium growth.

5. Water management. Mushroom rooms should always be well ventilated, and the air relative humidity should not exceed 95%. When the natural temperature reached 16 ℃, water was irrigated once in the border, and then sprayed once in the morning, in the middle and in the evening. Spray water into the space and the ground as much as possible, not on the fruiting body. It is best to spray warm water basked in the sun in the low temperature season.

6. Temperature management. The temperature of the mushroom shed should be controlled at 10 ℃ 18 min. When the temperature is low, the time of direct sunlight should be extended during the day, and the strict grass curtain should be covered at night. When the temperature is high, cover the grass curtain during the day and open it at night.

? 7. Ventilation management. When the temperature is high, the grass curtain should be opened and ventilated for 3 hours every day, low temperature and strong wind, less ventilation in the morning and evening before and after water spraying, less ventilation in the mushroom bud differentiation period, and more ventilation in the mushroom bud growth period.

? 8. Light management. During the growing period of mushroom buds, there should be stable scattered light, keep drying for 1 hour in the morning and evening every day, increase the direct light of low light, and avoid the direct light of strong light during the mushroom period.

? III. Pest control

Edible fungus itself is weak in resistance to insect pests, and it is not easy to control once it occurs. We should adhere to the principle of giving priority to prevention and comprehensive control, mainly from the selection of disease and insect resistant varieties, physical control, biological control and strengthening cultivation management and other ways to achieve the purpose of control.
