First, the selection of Pleurotus ostreatus varieties is very important. "The species didn't harvest." Many mushroom farmers don't know the temperature type of Pleurotus ostreatus varieties, so they plant them, and as a result, they don't produce mushrooms or fungus. Selection of high-temperature varieties: the fruiting body differentiation temperature can reach 36℃, and the optimum temperature is 20℃ ~ 28℃. Such as: Xiapinggao 1, others: Gaokang 48, Jiangdu 7 1, ReKang Wang, Xiayou 1, Gaoza 1, P40, Yage 1, Xia Feng 962, Fuyuan/kloc. Practice has proved that the yield of improved varieties is more than 30% higher than that of inferior varieties, with strong seed setting, even stubble times and less pests and diseases. Third, the location of the cultivation site of high-temperature Pleurotus ostreatus can be in the shade, big arch shed, semi-underground mushroom shed, summer vegetable shed, abandoned house, etc. The requirement is that the covering on the shed must be thick, well ventilated, convenient for drainage, far away from pollution sources and able to shelter from wind and rain. Four. Production, cultivation and management of fungus bags After introducing high-quality mother seeds, the original seeds can be produced in the middle and late March, the cultivated seeds can be produced in the late April to the early May, and the cultivation production can be carried out in the late May to the early June. Original seed formula: cottonseed hull 87.5%, bran 10%, urea 0.5%, gypsum 1%, sucrose 1%, moisture 60%. The formula of cultivated seeds does not use nitrogen-rich substances in principle, and can be selected as follows: 1. 96% of cottonseed hull, 2% of calcium superphosphate and 2% of quicklime; 2. cottonseed hull 100kg, calcium superphosphate 2kg, quicklime 2kg, urea 0.3kg3, cottonseed hull 96%, calcium superphosphate 1%, plant ash 1%, gypsum 1% and urea 0.3%; Using clinker to make bags, the ratio of material to water is 1: 1.5. After the raw materials are fully and evenly mixed, they are put into a polyethylene pipe with a length of 22cm× 45cm× 0.02cm, and are drilled for sterilization. When the central temperature of the pile reaches 100℃, it is kept at 100 hours or more. In summer, besides selecting high-quality strains, it is necessary to increase the inoculation amount. Spraying limewater and trichlorfon outdoors to kill miscellaneous bacteria and pests. It is necessary to prepare ingredients and inoculation in time to prevent contamination by miscellaneous bacteria during operation. The technical point is to control the temperature. After sterilization, naturally cool, inoculate the culture bag in the inoculation room, and spread the strain on both ends of the material surface by two-end inoculation method. Then put the bacterial bags on the indoor floor in a single layer, with the row spacing not less than 50 cm and the bag spacing not less than 5 cm. When the mycelium is full of shoulders, use a sewing needle to tie a circle of small holes at each end for ventilation. If the material temperature exceeds 35℃, sprinkle water on the ground and ventilate to cool down.

When the primordia appear, water management should be strengthened to make the relative humidity of air reach 90% ~ 95% (it is not allowed to spray water directly on the mushroom buds to cool and humidify), and ventilation should be appropriately increased. When mushrooms grow, they can be sprayed with water directly and the temperature should be controlled, preferably not exceeding 30℃. 5. Forest cover cultivation mode Forest cover cultivation: cutting bags 1/2, spacing 5-8 cm, covering 2/3 soil, leaving plastic bags at the mouth to moisten and germinate; You can also cover it flat, completely remove the bag, with a slightly larger spacing, water more, cover it with 2 ~ 3 cm of slightly fine granular soil, and cover it with a film to keep it moist until the mycelium is full. It can also be covered with a layer of wheat straw, which is moisturizing and breathable, and the grown mushrooms are cleaner. When the shading effect is not ideal, a shading net or grass curtain can be set. Forest cultivation should adopt high-density north-south woodland, which is light and conducive to ventilation, and the best row spacing is 2.5 ~ 3 meters. 6. Mushroom production management When the mycelium is full, the hand-pressed mushroom bag is firm and elastic, and yellow water drops and primordia appear on the surface, indicating that the mycelium has reached physiological maturity and can be piled up. The maximum size of the bacteria wall is three layers, and the bags should not be close together. To leave a gap of 3 ~ 5 cm for heat dissipation, you can use small bamboo poles to separate the layers. In summer, the temperature is high and the water evaporates quickly, so in order to ensure the humidity, water should be sprayed frequently, 3 ~ 5 times a day, to ensure the humidity needed for the normal growth and development of fruiting bodies. Micro-spray system can be installed, which is convenient to use and has good effect. 7. Harvesting: Pleurotus ostreatus can be harvested when the mushroom cover is 5 cm. After picking a tidal mushroom, clean the material surface once, stop water for two days, and spray 1 times of heavy water to promote bud growth, and 4 ~ 5 tidal mushrooms can be harvested. The time from sowing to fruiting of high-temperature Pleurotus ostreatus is fast and the management is standardized. Mushrooms can be produced in about 20 days, and the biotransformation rate can reach 100% ~ 130%. Eight, the main pest control: 1. Symptoms of yellow (brown) spot disease. Light yellow spots appear on the cap or the depression of the cap, and the young mushroom becomes sticky, stops growing and dies. Mushrooms grow slowly, lose their elasticity, break when touched slightly, become sticky, shrink, emit rotten smell, and diseases spread rapidly, causing the surface of cultivation materials to become sticky and stop fruiting.
