As the weather gradually turns cold, autumn and winter haze days are very unfavorable to crop growth in greenhouses, and the management of greenhouses during this period is critical. “Overcast and misty days will cause the illumination in the shed to weaken, and the temperature will decrease, which will affect the photosynthesis of plants, which is not conducive to the growth of the plants.” Professor Li Jianming of the College of Horticulture, Northwest A&F University, suggested that greenhouses should be made from both warming and filling. Management work.

Timely warming should be avoided. Heavy rain, hazy days, and stronger temperature management of greenhouses are the key to ensuring the normal growth of crops. “In addition to choosing a scientifically-designed greenhouse, the temperature can be increased by using a method of covering the insulation of greenhouses to increase the temperature in the greenhouse in time.” Li Jianming reminded farmers that many households were not used to keep their insulation warm. They were relatively thin and should attract attention. . In addition, the shed film must be cleaned and scrubbed regularly to remove dust from the top of the house in order to increase light and heat and increase the temperature of the shed.

It is necessary to fill the light at the right moment and light up the crops, Li Jianming said, farmers can use LED lights and other light sources installed in the shed to timely fill the light in the greenhouse to ensure that crops have sufficient light for photosynthesis. “In the case that the temperature during the day is not very low, we must timely uncover the cover of the greenhouse and keep the shed membrane clean so that scattered light can be used to obtain light for the growth of the crop,” said Li Jianming.
