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.

First, use Pleurotus ostreatus varieties. 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. 1Planting period of oyster mushroom. The sowing date of the early mushroom can be advanced to the end of August, and the wide-temperature variety or the medium-temperature type in the early stage and the low-temperature type in the later stage can be selected. 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 a large row spacing of 1 to 1.2 meters with a small row spacing of 0.5 to 0.7 meters. Plant spacing is 20 centimeters. 3,500 to 4,000 plants are planted per 667 square meters, and every 2 rows cover mulch film widths. 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. '

Fourth, mushroom management

I. The germination period management. After the mushroom is sown, the temperature of the culture material rises in the short term from germination to planting. If the hyphae exceeds 40t 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, regular inspection of the temperature changes in 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.

2. Sub-entity formation management. Environmental conditions conducive to the formation of fruiting bodies should be created to promote mushrooming. 1 increase the temperature difference between day and night: the daytime temperature should be 22 °C, 10 °C at night, temperature difference between day and night more than 10 °C to the formation of mushroom buds. 2 increase the scattering of light: appropriate increase in the indoor scattered light is conducive to the formation of fruiting bodies. But avoid direct light. 3 Increase ventilation: The formation of fruiting bodies is sensitive to carbon dioxide. When you plant the plastic film, stick it with a stick to increase ventilation. The bags are planted mainly by adjusting the amount of ventilation in the greenhouse, supplementing oxygen and removing carbon dioxide. Ventilate twice a day for half an hour. 4 increase the humidity: the relative humidity of the indoor air should be maintained 85% -90% during the formation of the first mushroom, generally do not spray water to the nutrient, to increase air humidity as the main water supply measures. When the fruiting body cover grows to 2-3 cm in diameter, a water spray can be used to spray water on the fruit body. 5 Harvesting: The fruit-bearing edge of the fruiting body changes from bent to stretched. When the spores have not yet been released, it is the best for the oyster mushroom, harvesting period. Harvested too late, mushroom nutrition for sporulation, tissue fibrosis, decreased quality; release of spores harmful to human health, and affect the formation of oyster mushrooms. 6 Post harvest management: After the first harvest, the debris of the broken mushroom was removed, the old roots were removed, and the water was stopped for 3 days. Then spray water gently to make the surface of the culture material moist (should avoid flooding), and the relative humidity of the air is kept at 90% and 95%. After about 10 days, the second mushroom bud is formed and the later management is the same as that of the first mushroom. ,

Usually sowed once; can harvest 3-4 mushroom. In the bag-growing oyster mushroom, after harvesting the second pod, the plastic bag of the bacterium bag is removed, and one of the pods is placed upright next to one another. The first one is dug and the other is covered with sandy soil. 1.5 cm thick, fill enough water, cover the plastic film, later management with the former.

V. Children's Note. 1 cucumber disease is more, need regular drug control, but must pay attention to the formation of mushrooms bud to spray or fumigation within about 10 days in order 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 incidence of cucumber diseases. 3 Respiration of oyster mushrooms 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 between oyster mushrooms is large, carbon dioxide may not be applied or lessened, so as to avoid carbon dioxide poisoning of cucumber and oyster mushroom. .
