North winter pingru cultivation points
The cultivation of Pleurotus ostreatus in the north can be divided into two periods according to the fruiting period: winter in autumn, winter in winter and cultivation in winter in winter. This article elaborates the technical points in the winter cultivation of Pleurotus ostreatus. 1. Choose the right variety: Different varieties are suitable for different mushrooming temperature. When the mushroom is in winter, it should be selected from wide-temperature and low-type dark gray varieties. For example: 2026, Xinping 106, etc. The darker the color is, the less likely it is to grow tumors. The back of the bacteria is fine and white, the overall shape is beautiful, and the product value is high. If you choose a darker black variety, the lower temperature in the shed will cause the back of the mushroom body to become dirty and watery, affecting the sales price. Winter cultivation of spring fruiting varieties should be selected mushroom body flesh thick, strong disease resistance, able to dry in the spring and the sand season of normal mushroom medium-temperature varieties, such as: Chuan miscellaneous 26,265 and so on. 2: Control culture material moisture: As the temperature is low in winter, mycelial respiration is greatly reduced, the consumption of water is reduced accordingly, so the moisture in the culture material should not be too large, the ratio of material to water should be controlled at about 1:1.3. At the same time, high-quality fungicides such as carbendazim and bacteriocin should be added to suppress the occurrence of green molds and green molds (chaetomium) during germination. 3. Increase the amount of inoculation: During winter bacteria growth, because the temperature is low, the growth of mycelium is slow. By increasing the amount of inoculum, the bacteria species can germinate as soon as possible to cover the entire material surface, forming the normal mycelium growth advantage of Pleurotus ostreatus. Inhibit the growth of bacteria. 4. Monitoring germination temperature: In order to maintain the temperature of the fungus bag, it can be piled up in stacks, stacking 6-8 layers in height, and can be covered with plastic sheets, straw curtains, etc., to keep the temperature between bacteria bags below 10 degrees and below 25 degrees. It is best to insert a thermometer between the bags to monitor the temperature of germs at any time. At the same time, pay attention to open the cover ventilation at noon every day for more than half an hour to ensure fresh air in the bacteria environment. After 7 days of inoculation, turn it over once every 3 days to ensure that the bacteria in the bag are consistent and there is no water in the bag. 5. Increase the light intensity of the mushrooming period: Lighting is an important way to increase the temperature of the mushroom shed. The intensity of the light directly affects the yield and quality of the oyster mushroom. The grasshoppers on the roof can be uncovered every day from 10am to 4pm, increasing the light and increasing the temperature of the shed. 6. Reducing the amount of water sprayed during the mushrooming period: In the winter, there is a lower temperature and a smaller amount of ventilation in the mushroom shed. The management is mainly based on insulation, and the water vapor in the shed evaporates slowly. Therefore, the amount of water sprayed in the mushroom shed must be controlled. . When the weather is clear and the temperature is relatively high, when the ventilation volume is relatively large, the water can be sprayed once every 1-2 days, and sprayed once every two to four days for a cloudy snow day, and the humidity within the shelter is kept between 85% and 90%. Remember not to spray "closed shed water" under unventilated conditions so as not to cause the mushroom body to rot and die. 7. To ensure the air circulation during the mushrooming period: In order to maintain the temperature in the greenhouse during the winter season, the ventilation is not enough, especially the semi-underground mushroom shed, due to lack of ventilation, the mushroom buds will not be differentiated or the stipe will be too long. Small malformed mushrooms. When the ventilation is seriously insufficient, it will cause death of carbon dioxide poisoning mushroom. Therefore, the winter shed should adopt a short-term, ground-savvy method, that is, ventilation 3-4 times a day, each time not more than 30 minutes. In foggy weather, it is necessary to pay attention to large ventilation to keep the air in the shed fresh; when there are temperature-increasing facilities in the shed, more attention should be paid to ventilation to prevent carbon monoxide poisoning. 8. Timely harvesting accelerates the speed of tidal changes: In winter, the metabolic rate of culture materials is relatively slow, so it can be harvested when the oyster mushrooms grow to seven to eight years of maturity. To prevent over-ageing and over-harvesting, the excessive rotation of nutrients in the culture materials will result in slower turning.
The Fiberglass Beams we produce are made of high quality fiberglass and the main function of the fiberglass beams is to support the floor of a pig cage.
