2. Miscanthus, which literally means "wheat with awn can be harvested quickly, and rice with awn can be planted", is also called "busy planting". It is a typical solar term reflecting agricultural phenology, the ninth solar term in the twenty-four solar terms and the third solar term in summer. On June 5th and 6th every year, when the sun reaches 75 degrees, it is mango. The temperature of awn seeds increased obviously and the rainfall was abundant. At this time, agricultural production in most parts of China is in the busy season of "three summers": summer harvest, summer sowing and summer management.

3. The word "ear seed" first appeared in Zhou Li. "Grass grows, ear seed grows." Zheng Xuan explained in the Eastern Han Dynasty that "Zecao can plant awn seeds, awn seeds, rice and wheat". Mango seeds have three stages, one is "mantis life" and the other is "mantis life"? (jú) The first sound ",the third" silent tongue ". During the period of ear planting, there are interesting customs such as "sending flowers to the gods" and "marrying trees" in leisure time. In order to adapt to the increasingly hot weather, the general eating habits will gradually become lighter.

4. Historical origin: Zhou Li once mentioned mango: "Zecao is born, mango species." Crops can be planted where there is grass. "Twenty-four solar terms" leaves once mentioned: "May Festival, there are awns 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, "awn seed", also known as "busy planting" and "busy planting", is the busiest time for farmers to sow and go to the fields.
