Pleurotus ostreatus cultivation: how to grow Pleurotus ostreatus with high yield?

How to grow tea tree mushroom can be high-yielding? Please introduce the method of planting Pleurotus ostreatus if you want to obtain high yield, you can refer to the following methods: first, select excellent strains: at present, there are two main sources of excellent strains of Pleurotus ostreatus planted by landlords in our country. one is the Institute of Fungi in Sanming City, Fujian Province. its fungus stalk is thick, the number of fruiting bodies is small, the color is dark, the cover is brown, the fruiting body is strong in high temperature tolerance, and the yield is high, but the taste of fresh mushrooms is slightly poor. The second is Guangchang, Jiangxi, where the stalk is fine, the number of fruiting bodies is large, the color is slightly light, the cap is reddish brown, the yield is slightly lower, but the meat is tender and the taste of fresh mushrooms is good. It is suggested that mushroom farmers introduce mother species directly from regular units to propagate. Method 2. Use the scientific formula: the nitrogen content of the culture material of Pleurotus ostreatus is too high, the pollution rate is high, the emergence of mushroom is late, and the nitrogen content is too low, the yield is low. The following two formulations are recommended: sawdust 36%, cottonseed hull 36%, wheat bran 20%, corn meal 5%, tea seed cake 1%, light calcium carbonate 1%, sugar 1%, pH 7: 7.5; or cottonseed hull 87%, wheat bran 10%, lime 2%, sugar 1%, water content 56% 60%, pH 7: 7.5. The third method is to improve the rate of bag-making products: first, the quality of culture materials should be fresh and mildew-free, and sawdust should be ripened and screened. The water content of the culture material should be suitable, with water stains on the fingers but not dripping. Second, bacterial bag production-cottonseed shell, sawdust should be pre-wet 24 hours in advance and add lime accumulation fermentation, then add wheat bran, mix and bag to the top stove for no more than 5 hours. Third, disinfection and sterilization-put the material bag into the atmospheric stove, generally 2500-3000 bags per stove, not too much. "attack, control and protect the tail" during sterilization, shorten the time of heating to 100 ℃ as much as possible, maintain 16-18 hours after the temperature reaches 100 ℃, and achieve complete sterilization. Fourth, strain culture-Pleurotus ostreatus is sensitive to light and temperature. The strain culture should be carried out under the condition of relatively constant temperature and avoiding light, the temperature should be controlled at 22 ~ 26 ℃, and the culture room should be checked every 10 days to remove the contaminated bacteria. Fifth, bacterial bag inoculation-after sterilization, the material temperature is cooled to less than 30 ℃, and then put into the inoculation box for inoculation. Try to reduce the damage of bacterial bags. Method 4. Scientifically arrange the bag-making season: the mycelium of Pleurotus ostreatus can grow at 5: 35 ℃, the optimum temperature for fruiting body differentiation is 22: 26 ℃, lower than 20 ℃, the fruiting body grows slowly, the tide turns slowly, the stipe is short, the yield is low, and the fruiting body grows fast and opens easily above 28 ℃, which affects the quality. Gaochun County is the most suitable for the formation and growth of the fruiting body of Pleurotus ostreatus in mid-late May and mid-September. It is a reasonable bag-making period to push forward 55 days and 60 days, and it is generally arranged to make bags in the first and middle of March and the first and middle of July. Method 5. Do a good job of integrated pest control: physical control and biological control are often used, and chemical control is not used as far as possible during mushroom emergence. Focus on environmental hygiene, timely disposal of waste bacteria bags, and disinfection inside and outside the mushroom room, using clean tap water to replenish water. The insect control method was combined with anti-insect net, black light and water immersion method (pouring water into the mushroom tube before the mushroom primordium appeared or after harvest, the water surface was 1mm higher than the material surface, and then dumped after 2 days).
