First, reasonable temperature rise
Taking Pleurotus ostreatus as an example, Pleurotus ostreatus does not grow below 5 °C. Even low-temperature strains such as 2006 and Special Resistant No. 1, etc., although physiological diseases do not occur at around 4 °C, temperatures of 10 ° C or higher are required. Well grown. Therefore, the warming and moisturizing in winter production has become a crucial management task. Generally, the temperature increase can be solved by means of daylight temperature increase and a furnace in the shed. However, when the stove is warming up, most mushroom farmers are often afraid of “running the hot air†and close the mushroom shed. As a result, the ventilation is seriously bad, the carbon dioxide accumulates, and the humidity is high. At the same time, the deformed mushroom will also cause some invasion. The occurrence of infectious diseases. Commonly used in the production of Camellia sinensis, Canton mushroom, Cauliflower mushroom, etc., and some invasive diseases such as rot disease are also closely related to poor ventilation and excessive humidity. Solution: Under natural conditions, when the weather is fine, the ventilation starts after 10:00 am and ends at around 14:00. Pull a layer of shade net or black film from the top of the shed to remove the sun and warm the sun, so that the heat enters and blocks the direct light. There will be different degrees of cooling during the ventilation process. As long as the air volume is not too large, it sometimes has a certain promoting effect on the development of mushrooms and fruiting bodies. Conditional water temperature and air conditioning can be installed, which can effectively adjust the temperature and temperature, and the equipment can blow out the circulating air to the mushroom shed to make the air in the shed fresh, avoiding various problems caused by poor ventilation.
Second, moderate moisturizing
Appropriate base material holding water and air humidity in the shed, collectively referred to as moisture, are generally regulated at 63% and 85% to 95%, respectively, to ensure the normal growth of hyphae and fruiting bodies. However, water is only one of the conditions for the growth of edible fungi, and it is not the only factor. Especially during the growth of fruiting bodies, proper ventilation is indispensable. The maintenance of ventilation and humidity is a contradiction between actual existence, and ventilation is dehumidification. In fact, under certain conditions, such as noon in winter, due to the proper introduction of air above the shed temperature, the shed temperature will rise slightly, and thus the evaporation of water in the shed will cause the humidity at this time to increase. Just as the temperature can stimulate the mushroom, a certain humidity difference sometimes promotes the effect of the mushroom, and, in the case of relatively low humidity, can also inhibit the survival and growth of certain diseases, but should be based on the fruiting body. At different stages, the humidity difference is controlled at 10% to 20% to achieve a better production result.
