Introduction of crop root research at home and abroad

The root system is an important part of the nutrients learned by a series of crops, such as water absorption, soil nutrients, and fertility. Therefore, an accurate understanding of the development of the crop root system has played a scientific basis for interpreting crop growth and estimating crop yield. Root analysis system is such a scientific instrument that can help us understand the growth and development of crop roots. It can deeply measure the length, area, volume, etc. of crop roots, and it is simple and powerful.

Although people are also well aware of the dialectical relationship between the growth of the above ground and underground, especially in the practice of dry farming, all the problems encountered involve all aspects of crop water relations. In dryland conditions, the water availability of unsaturated soils depends to a large extent on the state of the plant, first of all the state of the root system. Weaver et al. (1926) pointed out that it is very important to scientifically estimate crop yields by accurately understanding the characteristics of crop root development.

Even though the German scientist Hals (1724) began to study the root system of plants as early as the eighteenth century, due to limitations in research methods and workload, the research progressed in the following hundred years was slow. Later, researchers at home and abroad came to realize that as the root of the underground part, it is always closely linked with the soil on which it depends. It is a “root and soil system” in which water, fertilizer, gas, heat, and root are mutually ecological. The quantity and quality of the configuration volume, dynamics, and connotation factors of such a system are directly related to the formation of the aboveground part and the formation of childbirth. Since the 1980s, people have gradually turned their research topics to the root system, which has turned the isolated physiology of shoots to the study of the interaction between roots and shoots. Root physiology has become a very active field in crop physiology research.
