"The summer mushroom and long mushroom stage is in the season with higher temperatures, which is not good for the growth and development of the fruit body. At this time, poor management can easily induce diseases and prone to rotten mushrooms." July 27, Jujube in Dumen Street, Yilong County At the mushroom production base in Goucun, the agricultural technology experts of the County Agriculture and Rural Bureau looked at the growth of summer mushrooms and explained to large growers the management of summer mushrooms and the skills of more mushrooms. temperature control After entering July, the outside temperature began to rise rapidly. When the temperature rises above 28℃, cooling measures should be taken to increase the thickness of the mulch outside the greenhouse, such as adding a layer of grass thatch on the basis of a layer of grass thatch, or covering the grass thatch with a layer of wheat straw or corn stalks If necessary, pull a layer of shading net 50 cm above the grass thatch to keep the natural temperature in the greenhouse below 32℃. Humidity control The appropriate water content of the bacteria tube should be maintained. The water content of the bag matrix is ​​between 40% and 60%, which can produce mushrooms and grow normally. If the water content is less than 40%, mushroom buds are difficult to form. The water injection method can be used to replenish the bacteria rods in time. The method is: pour flowing water in the furrow during the day and drain it at night; when the bacteria tube is dry, you can directly spray clean water on the bacteria tube, usually once a day, sunny days Spray more. In rainy days, remove the water in the furrow in time. When the temperature is high, you can use spring water, well water and other low-temperature clean water every morning and evening to spray on the roof, surroundings and spaces to keep the shed in a cool environment. Keep ventilated Shiitake mushrooms are aerobic fungi. The fruit bodies grow extremely fast in summer and autumn, and the oxygen consumption increases sharply. The covering film is only to avoid rain. The film covering the mushroom bed should not be covered tightly. The surrounding film must be rolled more than 30 cm away from the mushroom bed to make the air between the mushroom beds smooth. In sultry and dry weather, it is not suitable to cover the film during the day. If the temperature of the tight-covered film rises, the carbon dioxide concentration increases, which will inevitably cause wilting and rotten mushrooms. There are more thunderstorms in the summer high temperature and high humidity season, and more attention should be paid to strengthening ventilation and dehumidification, so that the air in the shed is smooth, ensuring large ventilation, avoiding the phenomenon of rotten mushrooms caused by high temperature, extending the fruiting period, and improving yield and quality. Only in cold weather can we consider covering the film for a short time. Light adjustment Shiitake mushrooms are light-loving edible mushrooms, and it is more appropriate to maintain "two yang and eight yin" or "one yang and nine yin" for cooling in summer. In some mushroom farms, because the light is too dark, the caps of shiitake mushrooms are small and thin, and the stalks are long and thick; on the contrary, the light is too strong and the temperature is too high for fruiting. Prompt mushrooms in time When it is difficult to produce mushrooms at high temperatures in summer and the price of mushrooms is high, you can gently tap the tube with a shovel or a wooden board, which can usually induce a tide of mushrooms. But it should not be used frequently. The mushrooms are too small and dense, and can easily lead to rotten tubes. It should also be noted that the mushroom farms should be used in batches. Check often Combine mushroom picking every day and pay attention to observation. If pests and diseases or wilted buds and rotten mushrooms are found, they should be removed in time, and rotten roots should be eradicated, and the local area should be wiped with lime water to prevent the spread of pollution. What needs to be emphasized is that pesticides are prohibited to avoid contamination of the mushroom bodies. Harvesting points Due to the high temperature during the fruiting period of bag-grown shiitake mushrooms in summer, shiitake mushrooms grow faster. It usually takes 1 to 2 days from the buds to become mushrooms. For this reason, observe the growth of shiitake mushrooms every day, before the caps of shiitake mushrooms are broken. (At six minutes of maturity) Timely harvest. The harvest is once a day, once in the morning and evening in the hot weather, and the fresh export mushrooms are harvested 2 to 3 times a day. Immediately arrange after harvest, package and transport or refrigerate in time. Stop spraying water after harvesting a tidal mushroom to extend the ventilation time to allow the tube to recuperate; for some of the tube's nutrient insufficiency, spray with a yield-increasing agent to increase mycelial vigor and increase the yield of regenerated mushrooms. When white mycelium grows back from the mushroom picking part, the bud will be urged. During the period of high temperature from July to August, the principle of cultivating bacteria as the mainstay and fruiting as a supplement should be adhered to, and avoid slapping or focusing on water to promote the mushrooms, otherwise the mycelium will be damaged and the tube will be rotten.
