What role does the twenty-four solar terms have on agriculture in China?

Twenty-four solar terms are of great guiding significance to the arrangement of agricultural activities in China.

Twenty-four solar terms reflect seasonal changes, and the four seasons in warm temperate zone are the most obvious, and the most suitable areas are distributed in the middle and lower reaches of the Yellow River.

The establishment and development of the 24 solar terms are closely related to the development of agricultural production. In the early stage of agricultural production, due to farming activities such as sowing and harvesting, people began to gain insight into the relationship between nature and agricultural production, and realized the law of long storage in spring, summer, autumn and winter. By the Qin and Han Dynasties, agriculture had been quite developed, and there were complete 24 solar terms to guide agricultural production. China has always attached great importance to the utilization of farming season and season. In the Eastern Han Dynasty, the Moon Order for Four recorded that farming activities were arranged according to the month and solar terms, while in the Northern Wei Dynasty, the Book of Qi Yao Min made it clear that farming, planting and harvesting were arranged according to solar terms. Later generations also used the twenty-four solar terms as the basis for determining the farming season. With the progress of agricultural production, the content of the 24 solar terms tends to be rich, and the climate changes in different regions are different, so are agricultural activities.
