What are the phenological characteristics of mans solar terms?

The phenological characteristics of the Chinese Miscanthus solar terms are as follows:

1. Many seeds are waiting for mantis to grow.

2. When mango seeds wait for Peng to start singing.

3. Miscanthus chinensis was silent in the third phase.

The word "awn" of awn seed refers to the harvest of awned plants such as wheat, and the word "species" of awn seed refers to the season of sowing millet crops. The homonym of "awn seed" means that all crops are "busy sowing". "Twenty-four solar terms" said: "The May Festival means that there are awn crops in the valley." Every year around June 6th, the Gregorian calendar, the sun starts when it reaches 75 degrees. On June 6th, 201/year (the fifth day of the fifth lunar month), the middle and lower reaches of the Yangtze River in China entered the Huangmei season.

Meiyu is characterized by rainy days, heavy rainfall, high temperature, less sunshine and sometimes low temperature. The annual rainfall in rainy season in eastern China is about 1/3 (1/2 in some years). Meiyu in the middle and lower reaches of the Yangtze River generally occurs after June. At this time, rice, cotton and other crops are growing vigorously and need more water.

The reason for the formation of Meiyu is that after the end of winter, the intensity of cold air weakens and retreats northward, and the warm air in the south pushes northward accordingly, extending to the middle and lower reaches of the Yangtze River. However, at this time, the cold air in the north still has considerable power, so the cold and warm air in the Jianghuai basin dominate each other, forming a quasi-static front, resulting in rainy weather. After a period of time, the warm air finally defeated the cold air and occupied the Jianghuai Basin. When the rainy weather ended, the center of rain belt moved to Huanghuai basin. At this time, the Jianghuai basin is competing for seeds.
