Autumn and winter, cloudy days, do a good job in the greenhouse

    As the weather gradually turns cold, the autumn and winter haze days are very unfavorable for the growth of greenhouse crops. It is very important to manage the greenhouses in this period. “The rain and fog will cause the light 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 plants.” Li Jianming, a professor at the College of Horticulture of Northwest A&F University, suggested that the greenhouse should be well-developed from both warming and filling. Management work.

 

    Timely increase of temperature, do not care about the rain, fog, and day to strengthen the temperature management of the greenhouse is the key to ensure the normal growth of crops. “In addition to selecting a scientifically designed greenhouse, it is also possible to use a method for heat insulation in greenhouses to increase the temperature in the greenhouse in time.” Li Jianming reminded the majority of farmers that many farmers’ insulation is not standardized, relatively thin, and should attract attention. . In addition, the shed film should be cleaned and scrubbed frequently, and the dust on the surface should be removed to increase the light and heat and increase the temperature of the shed.

 

    It is necessary to light up lightly at the right time. It is necessary for farmers to use light sources such as LED lights in the shed to fill the greenhouses in time to ensure that the crops have sufficient light for photosynthesis. "In the case that the temperature is not very low during the day, it is necessary to uncover the cover of the greenhouse at the right time and keep the film clean, so as to use the scattered light to obtain light for the growth of the crop." Li Jianming stressed.
