First, reinforce the mushroom shed to prevent high winds from overturning the roof and Blizzard pressing the roof to cause losses;
Secondly, to increase temperature and heat preservation measures, it is best to use fire wall heating to heat the mushroom shed to prevent freezing damage. Even the buds are frozen to death. The northern wall of the mushroom shed must be as thick as possible or add insulation material in the middle to prevent it. In the northerly wind, greenhouse straw should be insulated by night with thick straw curtains or insulation.
Thirdly, to strengthen ventilation management, as edible fungi mainly rely on the decomposition of organic substances, which require oxygen in the metabolic process and release carbon dioxide at the same time. The purpose of ventilation is to supplement the oxygen needed by edible fungi, and to excrete the carbon dioxide produced by its metabolism, especially to enter into mushrooming. During the period, the oxygen demand and the amount of carbon dioxide generated will increase. If no ventilation will cause mushroom deformities or even death, the specific measures are: 1 to open the vent hole at noon, but the premise is not to make the temperature difference between inside and outside the shed 2 in the outside temperature 5 Above °C, the plastic film below the south of the shed is lifted by about 10 cm. The ventilation effect is very obvious.
Fourth, to strengthen the humidity control to ensure the moisture content of the culture material or mushroom stick and the relative humidity of the mushroom shed. It is best to hang several dry and wet thermometers inside the mushroom shed to monitor the temperature and relative humidity in the shed and maintain the normal value range. .
