In order to obtain appropriate small spray droplet size spectra and increase spray droplet velocity,so as to improve pesticide spray deposition rate,a method to improve spray deposition rate using PWM-based(pulse width modulation,PWM)intermittent variable spray technology was discussed.
为了得到合适的雾滴细度,提高雾滴运动速度,从而提高农药喷施沉积率,该文提出一种基于脉冲宽度调制(pulse width modulation,PWM)间歇喷雾的沉积率提高方法。
