There are not many examples of domestic adoption of this technology. In order to study the application of this method in crop root observations, we have accumulated experience, promoted the popularization and application of plant root image monitoring and analysis systems, and used the plant root image monitoring and analysis system to observe the maize root system. The square whole section method was used as the reference standard to analyze the root distribution of micro-root canal observation.
By analyzing the data obtained from the plant root image monitoring and analysis system, the obtained root length density decreases with increasing depth, which is consistent with the results of the square whole section of the standard wood method. The data obtained from the plant root image monitoring and analysis system has a significant correlation with the root length density of the square whole-segment method, and the correlation coefficient reaches 0.83 or more. The significance of the regression equation established during the analysis can be used to better evaluate the soil. The growth law of the maize root system, this method has the extension value in the study of root growth.

One of the important indicators of the growth and development status of crops is the growth dynamics of roots, which is also very important for the formation of yield. Studying the growth of roots is of great significance to the cultivation and management of crops. There are many methods for monitoring the growth of crop roots. There are traditional methods for sampling wood and modern high-tech methods. Each method has its own advantages and disadvantages, but it is less selective and accurate. method. The plant root image monitoring and analysis system is a modern and common monitoring instrument that can easily and accurately monitor the root system.
