Which season does the "mang" in the poems of the twenty-four solar terms refer to? What does he have to do with the busy farming season?

Crops with awns, such as awn seed wheat, mature and summer sowing begins. It is the ninth solar term among the twenty-four solar terms, and it is the awn species around June 5 every year. The sun reaches 75 degrees on the yellow meridian. "Twenty-four solar terms": "The May Festival means that there are awn crops in the valley". It means that the seeds of crops with awns, such as barley and wheat, are ripe 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, "busy", also known as "busy planting", is the busiest time for farmers to sow and go to the fields.
