What is the relationship between weather and solar terms?

Weather is the condition of solar farming, that is, natural conditions such as temperature, humidity and light. The solar term is the summary of working people's experience in mastering farming season in long-term production practice. In order to ensure the smooth progress of farming activities, we must accurately grasp the farming season.

Agriculture in China, especially ancient agriculture, was greatly influenced by "weather". Therefore, it is an important principle to master the changes of solar terms and arrange farming activities without violating the farming season.

The "solar terms" are fixed, but natural conditions often change. Agricultural production must be based on the change of solar terms, adjust measures to local conditions, and do not violate the arrangement of agricultural time, so that the growth and development process of crops can fully adapt to natural climate conditions.
