8 main points of edible fungi cultivation in summer
Cultivation of edible fungi in summer is difficult, because of the weather, it is easy to breed bacteria. How to reduce the infection rate has become the top priority of many edible fungus cultivation factories. Let's learn the main points of edible fungi cultivation in summer.
1. Select strains
Appropriate cultivated species and varieties should be selected according to local climate characteristics. Aged or contaminated strains should not be used. Robust, high-quality, disease-resistant strains should be used.
2. Fine management
Pay attention to the hygiene of raw materials, fungus bags and tools. Do not pile waste materials near the cultivation room, and use them after high temperature composting. The new and old fungus bags in the cultivation room must be separated and stored in separate rooms, and must not be mixed in order to achieve strict sterilization and disinfection to prevent vaccination and various secondary infections. After each mushroom picking, the roots, rotten mushrooms and mushrooms on the ground should be removed, and the mushroom house should be cleaned and re-sterilized in time.
3. Scientific sterilization
For different types of edible fungi, according to their requirements for growth and development conditions, scientifically regulate the temperature, humidity, light and pH value of the cultivation room, and appropriate ventilation should be adopted to promote the healthy growth of mycelium and prevent the occurrence of high temperatures. The unfavorable wet environment must be strictly controlled in the selection of strains, the proportion of culture materials, the fermentation of the stock, the inoculation of the germs and the management of the mushrooms, to cultivate strong mycelia and fruiting bodies and enhance their disease resistance.
4. Fertilization
Spraying the solution of peptone and yeast extract can make the mushroom body thick and promote the tide; spray the manure and urine of decomposed people, after spraying, you can spray again with clean water; spray rice vinegar. In the middle and late growth period of Pingru, use 300 times of edible rice vinegar for mushroom surface spraying, once a day for 1-3 days before harvest, generally increase the yield by 6%, and the color is more white; spray the culture material leaching solution, you can Extend the peak period of mushrooms and make the fruit body thicker; spraying glucose and calcium carbonate solution can promote the growth of mycelium.
4. Moisture management
The mushroom house should always be well ventilated, and the relative humidity of the air should not exceed 95%. When the natural temperature reaches 16 ° C, pour water into the furrow once, and then spray water once a day in the morning, middle and evening. Spray water as much as possible to the space and the ground, and do not spray it on the fruiting body. In the cold season, it is best to spray warm water with sunlight.
5. Temperature management
It is best to control the temperature of the mushroom shed at 10-18 ℃. When the temperature is low, extend the time of direct sunlight during the day and cover the grass curtain at night. When the temperature is high, cover the grass curtain during the day, and open the curtain at night.
6. Ventilation management
When the temperature is high, open the grass curtain to ventilate for 2 to 3 hours a day, less ventilation in low temperature and windy weather; increase ventilation before and after water spraying in the morning and evening, less ventilation during the mushroom bud differentiation period, and more ventilation during the growth period of the mushroom bud.
7. Lighting management
Mushroom buds must have stable scattered light during the growth period, insist on drying for 1-2 hours every morning and evening, increase the direct light of the weak light, and avoid the direct light of the strong light during the mushroom growing period.
8. Pest control
Edible fungi itself has weak resistance to pests and is not easy to control once it occurs. The principle of prevention first and comprehensive prevention and control should be adhered to, mainly through the selection of resistant varieties, physical prevention, biological prevention and strengthening cultivation management to achieve the prevention and control objectives.
