AI Technical Summary
Existing saline-alkali land remediation devices cannot ensure the uniformity of microbial agent application, nor can they control the amount of microbial agent applied according to the soil salinity, resulting in waste or insufficient use of microbial agents.
A variable-rate solid microbial agent application device was designed, comprising an equidistant spreading unit and an intelligent control unit. The device achieves equidistant spreading by driving a movable feeding plate with a hydraulic cylinder, and adjusts the feeding amount according to the salinity using a vision lens and a PLC controller.
This method enables uniform and equidistant application of solid microbial agents, improving their utilization rate, ensuring appropriate application in soils with varying salinity and alkalinity, and preventing waste.
