I. Selection of Pleurotus ostreatus
Greenhouse cultivation of vegetables should be in the winter and spring seasons, so the choice of middle and low temperature types of Pleurotus ostreatus. Late autumn and early spring should be based on moderate-temperature and wide-temperature varieties, such as West Germany 89, Sichuan hybrid 26, Sichuan Zaza 20 and so on. During the harsh winter season, low-temperature types should be used, such as 2026, spores, and CCEP99.
Second, the appropriate sowing
1 sowing time of mushroom: The sowing date of early mushroom can be advanced to the end of August. The wide temperature type or medium-temperature type is used in the early stage and the low-temperature type is used in the latter stage. The second crop is planted from late December to early February. The low temperature type is used in the early stage and the medium or wide temperature type is used in the later stage.
2 Vegetables Take cucumber for example and plant it in mid-October.
Third, cut the training method
Cucumbers are planted in 1-1.2-meter rows with a large row spacing of 0.5-0.7 meters. Plant spacing is 20 centimeters. 3500-4000 plants per acre are planted, and every 2 rows cover a plastic film such as a centimeter wide. Pleurotus ostreatus adopts a bag planting method. The bacteria bags are placed in large rows and can be stacked in layers of 3-5 layers with plastic film on top. This cultivation method is very conducive to the production of Pleurotus ostreatus. '
IV. Pleurotus ostreatus management
After the Pleurotus ostreatus is sown, the temperature of the culture material rises in the short term from germination to colonization. If the hyphae exceeds 40°C for a long time, it will grow poorly or even be suffocated. Within 3-4 days after sowing, special attention should be paid to ventilation and temperature adjustment work, regularly check the temperature changes within the culture material, the temperature can be slightly unmasked, so that the material temperature is controlled at 24-28 °C. Around 10 days, the seed blocks were covered with hyphae and spread neatly around the perimeter. About 30 days after sowing, the hyphae covered the whole culture material, and attention was paid to heat preservation and ventilation. If contamination of the bacteria is found, use a syringe to inject 75% alcohol or 0.1% potassium permanganate solution. Seal the hole with adhesive tape. During the whole period of germination, the room temperature was controlled at 22-28°C, the relative humidity of the air was 70%, and ventilation was conducted for at least half an hour every day. After the hyphae are covered with culture materials, the fruit body primordium can be formed within 10 days, and then enter the fruiting body formation period.
V. Child Remarks
1, cucumber disease is more, need regular medication control, but must pay attention to the formation of mushroom buds until the harvest about 10 days spraying or fumigation, so as to avoid pesticide residues. When spraying must be done, seal the flat mushroom with a plastic film before spraying.
2. Do not spray on the cucumber leaves when spraying water with Pleurotus ostreatus, and reduce the number of sprays to reduce the occurrence of cucumber diseases.
3. Respiration of Pleurotus ostreatus and culture materials produce a large amount of carbon dioxide by fermentation, which can basically supplement the photosynthesis requirements of cucumbers. When the sunlight is not strong or the volume of mushroom is large, carbon dioxide may not be applied or lessened, so as to avoid causing carbon dioxide of cucumber and mushroom. Poisoning.
Pleurotus ostreatus and vegetable intercropping cultivation method
Pleurotus ostreatus and vegetable intercropping is a high-yield, high-efficiency cultivation mode. It makes use of the characteristics of high stalked vegetables with large row spacing and large amount of empty land as the oyster mushroom, and achieves the double benefit of harvesting oyster mushrooms in the lower part of the upper harvested vegetables. . The stems and leaves of vegetables are used to shade the oyster mushrooms. The oxygen released from the photosynthesis of vegetables is used by the oyster mushroom. The respiration of the oyster mushroom and the carbon dioxide produced by the fermentation process of the cultivating material are the raw materials for the photosynthesis of the vegetables, forming a benign ecological cycle of mutual benefit and symbiosis. Intercropping vegetables and oyster mushrooms in greenhouses, vegetables, cucumbers, beans, cowpeas, cowpeas, tomatoes and other sorghum crops.
