Background
The action of the root system of the crop on the growth of the plant mainly comprises six aspects of absorption, conduction, fixation, synthesis, storage, propagation and the like. Absorption and transport are the most important functions of the root, including absorption and transport of moisture and mineral elements needed to maintain crop growth; the sessile finger root can maintain the shape of the overground part of the plant for vertical growth; the synthetic refers to that the root can synthesize amino acid and other substances which influence the growth and development of plants; the storage and propagation refer to the functions of the roots of the crops such as radish, sweet potato and the like. Factors influencing root growth include physical properties of soil, nutrients and water content, the physical properties include mechanical composition, porosity and the like of the soil, and the nutrient conditions include organic matters, nitrogen, phosphorus, potassium and trace element content in the soil, besides the characteristics of crops. The root system research mainly reflects the growth condition of the root system through 3 indexes, including (1) the maximum depth of the root system: refers to the maximum depth of the roots vertically distributed in the soil. (2) Main root system layer: the weight of the root in the soil body reaches more than 90 percent of the total weight of the root. (3) Dense root system layer: refers to the soil layer with the largest mass of roots. The root system of most crops is densely covered in a soil layer of 0-50cm, and the longest root system can reach more than 100 cm.
