1, Great Summer, one of the 24 solar terms, the last solar term in summer. Every year from July 22nd to 23rd in Gregorian calendar, the solar sun arrives at120th, which is a solar term in summer. Like summer heat, summer heat is also a festival reflecting the degree of summer heat, which means the weather is extremely hot.

At this time, the weather is hot and humid, which easily leads to excessive moisture in the body. Health care should not only know how to prevent heatstroke and cool down, but also pay attention to eliminating dampness.

3. Meteorological change: In the hot summer season, just before and after midsummer, the weather enters the hottest period of the year, which coincides with the same season of rain and heat, and the rainfall increases significantly compared with other months. During this period, farmers should always pay attention to the attack of heavy rain to prevent the occurrence of floods, and also do a good job in field preparations for drought resistance and crop protection.

4. Phenomenon: Ancient people in China divided the summer heat into three periods: "Rotten grass is firefly; Second, wait for the soil to moisten and cool off the heat; It will be fine when it rains. "

Every summer, due to the high temperature and rainy weather, bacteria are easy to breed, and many dead plants are wet and corrupt. At night, fireflies can often be seen flying around, looking for food on rotten grass and leaves. In addition, the soil is hot and humid, which is very suitable for the growth of water-loving crops such as rice. The third kind of weather means that rain will fall in the sky at any time in this hot and humid weather in the same season.
