Design and Experiment of Intelligent Control System of Crop Partial Root-zone Alternative Irrigation

The existing alternative irrigation devices are still stuck in the stage manually select the irrigated area through human operation to achieve the selected area of irrigation, timeconsuming, response speed is slow. The existing irrigation devices need to use other means of experimental observations to determine the actual moisture content of the different regions of the crop root zone to determine which area needs irrigation and when it needs irrigation, has seriously affected the （a）
