In the winter season, more foggy weather is not conducive to the production of vegetables in greenhouses. Farmers often do not know how to manage them to reduce losses. Yang Zhongan, a professor at the Agricultural Science Academy of Northwest Agriculture and Forestry University, reminded farmers that haze is common in early winter. This kind of weather has a great impact on the greenhouse vegetables, resulting in short illumination time, which is not conducive to photosynthesis and affects the normal growth of vegetables, resulting in yield. As the quality of the plant deteriorates and the quality of pests and diseases worsens, it is important to grasp the production and management points of greenhouse vegetables in the haze weather.
As early as the late cover, increase the temperature immediately after the haze spreads, open the grass cover, and appropriately delay the cover time at night to extend the lighting time, which is conducive to the increase of indoor temperature. Shorter vegetables, timely covered with a small shed, such as spinach, rape, cauliflower, cabbage, etc., can be covered with a small plastic shed above the vegetable shed, play a role in warming insulation.
Clean the shed film, increase the light by gently wiping the shed film with a dry mop or a clean soft cloth, remove dirt, grass clippings, leaves and other dirt on the shed film, increase the transparency of the shed film, and increase the indoor light intensity, which is beneficial to Increased temperature and the manufacture and accumulation of organic substances.
Scientifically watering, reducing disease and haze. The amount of water vapor in the air is very large, and the humidity in the greenhouse is also very large. At this time, try not to water or water, prevent the humidity in the greenhouse from increasing, and induce diseases.
