The analysis history of the root system is also relatively long-term. Under such a state, root research methods have also been summarized. From the beginning of the root research science to the present use of scientific computer technology, the analysis of the root system has not changed, but only the analysis has changed. Tool of. The application of modern root analysis system makes the analysis process more precise and comprehensive.
Because the root system is the underground vegetative organ of the crop, it not only absorbs the water and nutrients in the soil, but also fixes the plants. It is also a place for the synthesis and transformation of trace active substances such as amino acids and hormones. For the roots of the analysis of the history if it is also a thick historical data, in 1923 the United States vegetative ecologist Weaver first classic mining methods for root research, since then crop root research has gradually started, but the progress is slow. Since the 1980s, with the strengthening of people’s understanding of the importance of root systems and the continuous improvement of research methods and techniques, significant progress has been made in crop root research.
The basic principle of the root analysis system is to combine the scanning system with the graphic analysis software. The image analysis software is used to analyze the root image of the scan, and the root length, surface area, volume, and number of root tips are calculated. Among them, the RootVizFS system can take all-round photographs of the root stereoscopic X-ray images. It is a non-destructive in-situ analysis system and is very suitable for studying the dynamic response of plant roots to stress. The application of the root analysis system has reduced the difficulty for the researchers to obtain the root parameters, but the high accuracy and dynamic monitoring of the whole root system of field plants is still difficult to achieve.
