In the continuous haze weather, many vegetable farmers ignore the importance of light and often put temperature increase first. The way to increase temperature is to ignite in the shed, and continue to increase temperature day and night. The author believes that such a blind temperature increase is not desirable. Blind warming is not good for vegetable growth. Regardless of whether it is sunny or hazy, vegetables must breathe, and the breathing is to absorb oxygen to produce carbon dioxide. The breathing process is the conversion of crops to organic matter. . In terms of vegetable management, we pay attention to maintaining the temperature difference between day and night. The purpose is to reduce the night temperature, reduce respiratory consumption, and promote the delivery of photosynthetic products as much as possible, instead of maintaining higher temperatures at night to accelerate breathing. If you do this, the respiration will be stronger, and the decomposition of photosynthetic products will be accelerated. Instead, it will promote the growth of vegetables, resulting in large and thin vegetable leaves and long joints. Therefore, under continuous haze weather, when light becomes a stress, there is little production of photosynthetic products, and when the nutrients accumulated in the stems and leaves of vegetables are limited, such a malignant warming, especially at night, will accelerate the respiration of vegetables and accelerate Plant nutritional consumption will leave the vegetables in an "idling" state. Over time, it will inevitably lead to premature senescence of the plants and the result of "fat and yellow muscle". Disclaimer: Some articles on this website are transferred from the Internet.
