"Fu Jia, for people who are also human beings, life is also the land, and raising is also the sky." Agriculture is a social industry that uses biological activities to produce, and its basic logic is life logic and ecological logic.
Because the growth and development of crops are closely related to light, temperature, gas, heat, water and other factors, agricultural production activities must conform to the seasonal and climatic characteristics of crop growth environment, which requires people to accurately observe the weather and grasp the farming season. As the saying goes, "there is no fixed method for farming, and it all depends on the solar terms."
