      Abstract:
      Objective To meet the requirements of precision fertilizer apparatus' s real-time variable additional fertilizer in the process of rice and wheat growth.
      Method  A new type of shaft segmentationvariable fertilizer applicator' s actuator was designed, whose overall structures of variable fertilization executing agencies and field theory was described. The structure and parameters of its key components wereanalyzed and identified. A fertilizer discharge performance test and field additional fertilizer tests werecarried out with nitrogen fertilizer.
      Result and conclusion The precision fertilizer applicator actuatorcould realize double regulation of slot wheel speed and jaw opening of conventional grooved wheel fertilizer discharge apparatus. The control accuracy of the overall system exceeded 90%. Fertilizer quantity adjusted dynamically in real time was helpful for managing and using fertilizer sufficiently. The precisionfertilizer applicator actuator can achieve acute additional fertilizer in precise agriculture and realize thedesign requirements.
