Late spring and early summer is a good time to cultivate oyster mushrooms. Pleurotus ostreatus is high in temperature during the fruiting period, and has many diseases. The planting volume is relatively small, but its price is 2 to 3 times that of autumn and winter. High-temperature mushroom cultivation technology is difficult and the success rate is extremely low. Therefore, how to obtain high quality and high yield is a problem that Mushroom farmers are more concerned about. Variety selection Many farmers have failed in the cultivation of high-temperature oyster mushrooms, which are caused by a variety of selection errors. Some farmers did not clarify the species's temperature type and planted it casually. The result was that the temperature was not correct, resulting in failure to produce mushrooms or germs. Therefore, it is imperative that they be introduced to high-reputation research institutes. Guarantee bacterial quality It is important to ensure the good quality of the strains in order to achieve high yields and stable production of high-temperature oyster mushrooms and to master the correct production process of strains. The improved varieties can produce more than 30% of the crops, and they are strong and the pests and diseases rarely occur. Venue selection The high temperature Pleurotus ostreatus can be used as a large shed, a semi-underground mushroom shed, a summer idle vegetable shed, and abandoned houses. The requirement is that the covering on the shed must be thick, well ventilated, and easy to drain. Fungus bag making Can adopt two methods of clinker bag making and fermentation material bag making, can not adopt raw material cultivation, otherwise it will produce failure. Clinker clinker cultivation refers to the method of sterilizing the culture material after high temperature sterilization, and then sowing and sterilizing. The cultivation of Pleurotus ostreatus is most suitable in this way. The benefits are as follows: 1 After sterilizing the culture material by high temperature, the nutrition in the material can be fully decomposed, and the nutrient utilization rate of the mycelium is high. 2 After this method is adopted , It is safe to add a variety of nutrients without having to worry about bacteria contamination in the bacteria-producing period; 3 the material temperature of the clinker cultivation can be well controlled, can prevent the burning of raw materials Phenomenon; 4 clinker cultivation mushroom early, sowing the same period, compared with raw material cultivation in advance of the mushroom 10 to 15 days. The size of the clinker bag can be selected from 20 cm 45 cm 2.5 to 3 silk, not too thick or too thin. The fermented material bag is suitable for mushroom farmers with rich germination experience. Specific measures: After mixing the culture materials with water and mixing them, build a 1.5-meter-wide, 1.2-1.5-meter-high, and unlimited-length material pile. The dry amount of material piles should be more than 500 kg, and it should not be too small to avoid material temperature. Raise or rise too slowly. The upper part of the stockpiling should be piled into a turtle shape, lightly lapped around, and use a wooden stick with a diameter of about 5 cm to make two rows of breathable eyes at the top of the stack, and then diagonally play a row of air holes in the middle and lower part of the stack. The hole spacing can be about 30 centimeters, covered with straw, sacks, scale bags and so on. After the stack is covered, use a thermometer to measure the temperature at about 25 cm above the surface of the material. When the temperature rises above 55°C, start timing, maintain for about 12 hours, and then turn it over. Before the material is fermented, it is usually necessary to turn it three times. The method of turning the heap is to transfer the stack up and down, and adjust the internal and external phases. After the stack is completed, the stack is rebuilt. The operation is the same as when the stack was built. After the material is well fermented, the stack is cooled down. When the temperature drops to about 30°C, it can be bagged. The bag size can be selected from 22 to 25 cm, 45 cm, 1.5 to 2 silk plastic bags. The sowing method is to use four layers of three layers of culture materials for layered sowing. After sowing a good seed, it should be perforated around the material bag and at the two heads of bacteria, and 8 to 10 vent holes can be provided at each of the two ends and the middle of each strain. Fungal management In summer, the temperature is high and the germs are difficult to produce. The bacteria bags should be properly discharged, and the bags should be turned and the oxygen should be ventilated in a timely manner to control the temperature of the germs and the ambient temperature. Whether it is a clinker fungus bag or a fermentation material fungus bag, it should be discharged in a single layer with a spacing of not less than 50 cm and a spacing of not less than 5 cm. Fodder sites should be strengthened with shading, and the intensity of ventilation and heat dissipation should be increased. If necessary, cold water can be sprayed on the bacterial bags to prevent temperature from exceeding 33°C. Mushroom management When the mycelium is full of hair, the hand bags are rigid and firm, flexible, and the surface has pale yellow water droplets and primordia, indicating that the hyphae have reached a physiological maturity. When 80% of the bacteria bags have a primordial appearance, they can be stacked and packed. The bacteria wall can be coded up to three layers, and the bag and the bag must not be in close contact with each other. A space of 3 to 5 cm should be reserved for heat dissipation. The layers can be separated from each other by small bamboo baskets. Throughout the process of mushrooming, ventilation must be good; due to the high temperatures in the summer, the water evaporates quickly, so to ensure humidity, water can be sprayed 3 to 4 times a day, and can be used once every few days with a large water shed. Pleurotus ostreatus from sowing to mushrooming, faster time, normal management, about 20 days can be fruiting, bioconversion rate can reach 100 to 130%.
