Fertilizer applying device for water chestnut planting
InactiveCN112930825AImprove practicalityPrecision fertilizationFertiliser distributersPressurised distribution of liquid fertiliserAgricultural scienceWater Chestnuts
The invention relates to the technical field of water chestnut planting, in particular to a fertilizer applying device for water chestnut planting. The fertilizer applying device comprises a moving seat, wherein a through hole is formed in the moving seat, electric extendable rods are symmetrically arranged on the positions, located at two sides of the through hole, of the top surface of the moving seat, a supporting plate is fixedly arranged at the tops of the electric extendable rods, mounting plates are symmetrically and fixedly arranged on the bottom surface of the supporting plate, fertilizer applying mechanisms are arranged on the mounting plates, and each fertilizer applying mechanism comprises a tank body rotationally connected between the two mounting plates and a plurality of fertilizer applying units arranged on the tank body. The fertilizer applying mechanisms are arranged, compared with an existing fertilizer applying device, fertilizers are applied through a spraying or soil burying mode, and the device can accurately apply the fertilizers to a single water chestnut plant in a targeted mode, so that fertilizer waste is avoided, the fertilizer absorption effect of water chestnuts is greatly improved, fertilizer applying can be completed only by pushing the moving seat, and time and labor are saved.
