Twenty-four solar terms awn species

Mango is the ninth solar term in the twenty-four solar terms of the lunar calendar and the third solar term in summer, which indicates the official start of the midsummer season.

The literal meaning of awn seed is "the wheat with awn is harvested quickly, and the rice with awn can be planted". "The Moon Order is seventy-two waiting for Ji Jie": "The May Festival means that there are awns in the valley." At this time, the middle and lower reaches of the Yangtze River in China will enter the rainy Huangmei season.

Spring competes for the sun, and summer competes for time. "Race against time" refers to the busy farming season at this time. People often say that the "three summers" are busy farming seasons, that is, summer management is busy with summer harvest, summer sowing and spring sowing crops.

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". Therefore, "awn seed" is also called "busy planting" and "busy planting", which is the spread and sowing of farmers' friends. The arrival of "Mangzi" indicates that farmers have started their busy field life.

Historical background:

The Yangtze River is in the ear sowing season, and the Huanghuai Plain is about to enter the rainy season. If there is continuous rain, strong wind and hail before and after ear planting, and the wheat can't be harvested, threshed and stored in time, it will lead to the lodging, grain dropping, germination and mildew of the ear, "rotten wheat field" and destroy the crops in front of us.

Behind the scenes, the monsoon rain belt in southeastern South China is stable, which is the season with the most precipitation in a year. The middle and lower reaches of the Yangtze River have entered the rainy season one after another, with more rainy days, more rainfall, less sunshine and sometimes lower temperatures.

In the awning season, rice, cotton and other crops grow vigorously and need a lot of water, and moderate plum rain is very beneficial to agricultural production; In the years when the plum rains are too late or too little or even "empty plum blossoms", crops will be threatened by drought. However, if the rainy days are too early, too many rainy days and too few long-term rainy days, it will also have a negative impact on agricultural production, especially if the rainfall is too concentrated or heavy rain will cause floods.
