Study on Water Uptake of Crop Root by Root Analysis System When the crop grows, it needs sufficient water to ensure the normal production of the crop. According to the survey, more than 80% of the water is absorbed by the root system. Therefore, the root system analysis system can effectively help us understand the crop's moisture absorption. The situation has greatly helped to rationalize irrigation, fertilization, and breeding to ultimately increase crop yield and productivity. Crop roots include downwardly growing main roots and lateral roots along the main root and their multi-stage branching roots. The dicotyledonous crop mainly grows downward from the roots formed by the elongation of the radicles, and some lateral roots produced from the roots also have a downward growth habit. The monocotyledons originate from the embryonic primordium. The primary roots derived from the lower part of the hypocotyls and the primary primordium originate from the leaf primordium. The secondary roots produced from the tiller nodes are downward growth roots, and each can develop one or more lateral roots. Straight roots or primary roots, and secondary root elongations determine the depth of roots under the crop, and the root length density depends on the number and length of their lateral roots. Root growth and development and morphological characteristics are the result of biological and environmental factors. In the field, soil conditions have a much greater impact on crop roots than genetic characteristics. Changes in water conditions often lead to differences in root growth and distribution. main reason. Root growth is the result of cell bulging in the elongation zone. The root system of crops can be adapted according to the soil moisture status. The degree of adaptability depends on the crop species, development stage, soil conditions, and atmospheric evaporation. It is precisely this kind of survival adaptation mechanism that becomes the basis of our regulation. Too much or too little soil moisture will change the size, quantity and distribution of crop roots, thus affecting canopy growth and grain yield. The universal conclusion is that there is too little water, the roots extend everywhere, the water source is chased, and carbohydrates are competed between roots and canopies. To avoid water stress and promote root growth, more assimilates are distributed to the root system, and the crown is restricted by water, and the growth is not. Wang, making the root to crown ratio increased. On the contrary, if there is too much water, the ventilation condition of the soil is poor, the growth and development of the root system is inhibited, and the assimilate is used in the crown to make the ratio of root to shoot lower. The ratio of root to shoot was significantly negatively related to soil water content, and the growth and distribution of roots fully reflected the advantages of crops in terms of their advantages and disadvantages. The root distribution will also be adjusted according to the soil water supply situation. If there is still available moisture in the soil after the midday drought, the roots are more likely to extend vertically, the root system is generally dense, the upper layer water is sufficient, and the root system develops horizontally. Shallow and wide distribution. It can be seen that artificially controlling the soil moisture status through irrigation will play a role in regulating root size and distribution.
