摘　　要：In order to test properties of a fertilizer feeder,the authors designed a testing system based on single-chip control in the computer platform.The actual working conditions of a fertilizer feeder in the field were simulated by altering the rotating velocity of feeder axle through the stepper motor.The discharging volume data of the fertilizer were acquired through the sampling of the pressure sensor.Eventually the fertilizer flow simulacrum was acquired from the results of the numerical analysis.Compared with traditional means of the optoelectronic sensor and image processing,the testing system illustrated in this paper can evaluate the discharging uniformity of fertilizer feeder with simpler hardware structure and less error.
