The twenty-four solar terms are coming. As the peak of "cooking mode", what effect does high temperature have on crops?

Solar terms and summer heat are the hottest time and the hottest time. Some netizens even directly called the summer heat, called cooking mode. Such solar terms not only bring discomfort to themselves, but also are extremely unfavorable to crops. So what's the effect of high temperature on crops?

1. Reduce the yield and quality. Crops in high temperature environment can easily lead to the inactivation of plant chlorophyll, thus reducing photosynthesis. In particular, high temperature during the day will inhibit plant photosynthesis and reduce the synthesis and accumulation of sugar. If there is high temperature at night, it will accelerate the respiration of plants and make them consume more nutrients, thus reducing the yield and quality.

2. Obstruct pigment formation. For crops, some fruits need to be colored, such as tomatoes, eggplant and other vegetables. If it is easy to hinder the formation of pigment in high temperature environment, it is not conducive to the color change of fruit, which will eventually lead to yellow-white phenomenon.

3. The occurrence of viral diseases. High temperature environment is easy to lead to drought, and crops are prone to virus diseases during drought. For example, vegetables and fruits tend to grow too small or deformed, which will make crops lose their commodity value or greatly reduce their commodity value.

4. Affect pollen activity. Crops in high temperature environment will also affect flower bud differentiation, especially fruits and vegetables, which will easily lead to the decrease of female flowers. This state is not conducive to the pollen activity of crops, or uneven pollination, which is easy to lead to a significant decline in yield in the later stage.

5. Dry up and die. If the heat is severe and the temperature is high, it is in a hot and dry state. It will accelerate the evaporation of water in plants, and a large amount of water will be used for transpiration and heat dissipation, which will destroy the water balance in plants. When the situation is mild, wilting and dryness may occur, but failure to rescue or replenish water in time during this period may probably lead to the death of later crops.
