How do shed dishes cope with foggy days?
First, the impact of foggy days on greenhouse vegetables First, the lack of light in the fog, reducing the photosynthesis of vegetables in the greenhouse, reducing the photosynthetic products, can not meet the nutrients needed for vegetable growth, affecting growth. Second, in the foggy days, the temperature in the greenhouse is difficult to rise. Under normal circumstances, the temperature in the greenhouse, at night at 15 ° C, during the day at 15-20 ° C, can not meet the temperature required for the normal growth of vegetables, easy to form small old seedlings, rigid seedlings. In addition, after the fog has passed, it is easy to occur or spread various diseases. Second, the response measures First, clean the shed film and increase the light. Gently wipe the shed film with a dry mop or a clean soft cloth to remove the transparency of the shed film and improve the indoor light intensity, which is conducive to temperature increase and the manufacture and accumulation of organic substances. Secondly, the grass is covered and the temperature is raised. Immediately after the fog is scattered, the grasshoppers are uncovered, and the cover time is postponed as much as possible in the evening, and the illumination time is prolonged, which is favorable for the indoor temperature to rise. Small arch sheds are added to the shorter plants. In addition, scientific watering is needed to reduce disease. Try not to water the water in the fog to prevent the increase of indoor humidity to create conditions for various diseases. If the soil is too dry and not poured, try to pour small water or use a method of dark casting under the membrane. Disclaimer: Some articles on this website are transferred from the Internet.
