To improve the fertilization accuracy and distribution uniformity of nitrogen fertilizer, control method of working parameters coordinate match was proposed in this paper. Take minimum coefficient of variation as criterion, the nearly-optimal set of exposure length and rotational speed was solved based on regression models with known values of target fertilizer amount and operating speed, the interfaces were built to rapidly calculate related parameters. The static and dynamic experiments were conducted to verify the reliability and accuracy of regression models and control method; the results showed that under static conditions, the biggest difference value of fertilizer amount is 0.22g per revolution; under dynamic conditions, the deviation of fertilizer amount is less than 4.01%, the maximum deviation of rotational speed is 2.74%. Those results indicate that the control method is practical and feasible for fertilization operation.
