Abstract

Since 2016 China liberalized its third-child policy, which resulted in an increase of millions of people every year and therefore China must ensure annual output increases. The utilization efficiency of water and fertilizer is one of the most important keys to mitigating the food crisis. Artificial intelligence technology will be the development of Chinese agriculture. However, the physical and chemical properties of soil, the selection of seeds, the characteristics of different crops, the proportion of water and fertilizer regulation, and the different tillage methods all affect the grain output and the sustainable development of tillage mode. The purpose of this paper is to find the direct relationship between tillage mode and water and fertilizer regulation, and summarize some rules. To provide data and theoretical support for the implementation of China’s modern agriculture. Therefore, winter wheat (wheat breed: Ji wheat 22) as the study crop was targeted, two irrigation methods: traditional irrigation (A) and water-saving irrigation (B) were selected, three fertilization factors: no fertilization (CK), traditional fertilization (FC) and optimized fertilization (FO) were chosen. Water and nitrogen fertilizer were used as control variables. This paper analyzes the environmental benefits of winter wheat irrigation and fertilization and provides a theoretical basis for rotation system efficiency and the sustainable production of winter wheat in a plain area. The results suggested that the water-saving irrigation mode had significantly better nitrate absorption efficiency of soil. The water-saving model is more conducive to improving the nitrogen absorption efficiency by the soil.
