What is the explanation of the meaning of mans solar terms?

Awning seeds mean the maturity of awned crops, such as wheat. Mango is the ninth of the 24 solar terms. On June 5th, every year, when the sun reaches 75 degrees, it is a kind of awn. Mango seeds refer to the mature seeds of awned crops such as barley and wheat, and it is very urgent to grab the harvest. Summer sowing crops such as late rice, millet and millet are also the busiest season for sowing, so they are also called "awn seeds". Spring competes for the sun, and summer competes for time. "Race against time" refers to the busy farming season at this time. It is often said that "three summers" is a busy farming season, that is, summer management is busy with summer harvest, summer sowing and spring sowing crops. Therefore, "awn seed", also known as "busy planting" and "busy planting", is the busiest time for farmers to sow and go to the fields.

It is a solar term in the turning period between Xiaoman and the summer solstice. The summer solstice is longer and the winter solstice is shorter. During the awning period, the sun will approach the northernmost part of its trajectory in the northern hemisphere day by day, and the longest day in the northern hemisphere is coming.

In southern China, the rainy season in early summer comes from the awning season, with abundant rainfall and significant temperature rise. At this time, the Huanghuai Plain will also enter the rainy season. If there is continuous rain, wind, hail and other weather before and after the ear seed, wheat can not be harvested, threshed and stored in time. Southwest China has entered the rainy season of the year, and the hail weather on the plateau has begun to increase. During this period, except the Qinghai-Tibet Plateau and the northernmost part of Heilongjiang, people in most parts of the country can experience the heat in summer.
