Agriculture is the human 'mother industry', and is the foundation for human beings to resist natural threats and depend on survival in ancient times of human hair shaving and blood drinking, so that agriculture is capable of surviving and developing human beings, and no agriculture is available, and no human modern civilization exists. The development of social production starts from agriculture, and only on the basis of the development of agriculture does the industry generate and develop, and only on the basis of the development of agriculture and industry does the industry develop. Thus, agriculture is a creditable "maternal industry". The status and effects of agriculture can be summarized in a sentence as the "basis of national economy".

The agricultural development as a whole is a feedback from the development of the industry, so the industry is always relatively lagged behind, and the innovation thereof is based on the prior industrial technology. Emerging technologies are difficult to fall on agriculture for the first time. Since there is a period of technological development, costs are always high in the initial stage and agricultural production does not afford high costs. That is to say, the development of agriculture is not departing from the overall progress of human science and technology, although people take food as the day, we always go to improve in the next step for agricultural production, for example, on the earthing press machine of the seeder, the press wheels with different sizes are replaced according to the requirements of seedlings with different sizes when the existing earthing press wheel is used for earthing and pressing, the reason for replacement is that the sizes of the seedlings are different, the space occupied by the blades is different, the space for accommodating the seedlings and the blades in the middle of the large press wheel is larger, and the space for accommodating the seedlings and the blades in the middle of the small press wheel is smaller; the replacement of the press wheel takes more working time, and the seeding speed is reduced; the cost of providing a plurality of press wheels of different sizes with one sowing machine is also high.
