[0002] Drip irrigation is one of the most water-saving irrigation technologies for farmland irrigation to date. However, due to its high price, it was once called an "expensive technology" and was only used for high-value-added cash crops. In recent years, with the widespread application of drip irrigation tape, the "expensive technology" is no longer expensive and can be applied to ordinary field crops. By supplying water through controllable pipelines, it can be mixed with pesticides to achieve drip irrigation and pesticide application to the crop roots.

[0003] Crops (such as sugar beets) can suffer from growth restriction or death due to infection with soil pathogens and underground pests. In order to control diseases and underground pests, it is of great significance to screen environmentally friendly and efficient pesticides. However, the application and efficacy evaluation require feasible field and experimental operating systems. Therefore, there is a need for a crop root drip irrigation system for evaluating the effects of multiple pesticides, which can meet the needs of small-scale trials and large-scale field application for pest and disease control.
