In this paper, aiming at the situation that it is difficult to control the amount of natural rubber fertilizer mechanically, this paper introduces in detail a kind of rubber ditch electric control ditching and fertilization combined operation machine, and its control principle, main structure and characteristics are described. The test: the use of electric control precision fertilization control system to take the first booster and then speed mode, the tractor carrier effectively achieve the Promise speed control knob can basically achieve the rubber fertilization precision control, The precision index reaches 94.3%. The fertilization equipment equipped with the control system matches the 80-horsepower tractor. The ditching depth can reach 22cm, the productivity is 1.23hm2/h, the fuel consumption is 3.1kg/hm2, the fertilization uniformity is 90.3% and the coverage rate is up to 98.0% , can effectively improve production efficiency and reduce production costs.
