The root system is an important organ for crops to absorb water and nutrients. Most of the water and nutrients necessary for crop growth are absorbed through the root system. To meet the needs of crop growth and development. With the development and progress of science and technology, the root analyzer has been widely used in root analysis, and the root analyzer can intuitively detect the development and release of crop roots, helping us to understand crop root development more clearly. Roots are widely distributed in the soil and constantly elongate, chasing water and nutrients in the soil, which is very important for satisfying self and aboveground growth. When crops encounter crop water stress due to transpiration rate exceeding root water absorption rate; or nutrient deficit due to low activity of nutrient elements in soil moisture solution; or both, crop roots and seedlings Growth and yield are very limited, and a series of changes occur in the physiological characteristics of the root system. In the Loess Plateau region of semi-arid climate in northern China, the source and yield of water needed for crop growth depends to a large extent on the possibility of the crop's increased use of soil moisture. How to use nitrogen and phosphorus fertilizers to regulate the use of water in the soil to promote The root system of wheat grows harmoniously and improves the water use efficiency. There is currently no research report. The purpose of this study was to investigate the effects of soil moisture and nitrogen and phosphorus nutrition on root growth and water use efficiency of wheat; appropriate amounts of N and P fertilizers under different water deficits; effective methods to promote root growth and increase water use; to promote crops in dry farming areas Root-based stress growth and production potential development provide scientific basis.
