What are the phenological characteristics of intense heat?

The phenological characteristics of midsummer season are as follows: (1) The rotten grass is firefly; Second, wait for the soil to moisten and cool off the heat; Just when it rains heavily.

Terrestrial fireflies lay eggs on hay. In summer, fireflies ovulate, so the ancients thought fireflies were made of rotten grass. During the hot summer, the weather began to get sultry and the land was very wet. There are often strong thunderstorms, which weaken the heat and humidity in summer and the weather begins to transition to early autumn.

Solar agriculture:

Around "Big Summer", the temperature is the highest in a year, and crops grow fastest. Agricultural production is closely related to geographical and climatic conditions. Monsoon climate is the main feature of China climate. Monsoon climate is a mixture of continental climate and maritime climate. Monsoon climate is characterized by simultaneous rain and heat, which is beneficial to crop growth.

Judging from the seasonal distribution of precipitation, precipitation in China is mainly concentrated in summer, especially in summer solar terms, which is a long-term crazy season for everything. In high temperature season, crops grow vigorously and need a lot of water, and summer is the season with the most precipitation and concentration in China. The high temperature period coincides with the rainy season, and the water and heat are well coordinated, which is very beneficial to crop growth.

Because the precipitation in China is mainly formed by the water vapor brought by the southeast monsoon, influenced by the summer monsoon, the precipitation gradually decreases from the southeast coast to the northwest inland.
