果园喷雾机利用风机产生的气流将雾滴输送至靶标 ,携带有细小雾滴的气流驱动果树叶片翻动 ,使叶面的正、反面都能着药 ,大大提高了药液在靶标上的覆盖密度和均匀度 ,可使药液的利用率达到 30 %以上。雾滴在果树上的沉积分布主要受果园风送式喷雾机风机风速的影响 ,而风机的风速主要由风量来决定。该文通过改变风机风量 ,探讨了树冠内风速的变化规律对农药在靶标上沉积量的影响 ,得到了雾滴在冠层内的穿透性和沉积量与风速呈正相关的结论
The orchard sprayer uses the air flow produced by the fan to deliver the droplets to the target. The airflow carrying the small droplets drifts the fruit leaves to turn, making the front and the back of the foliage medicine, greatly improving the coverage density of the liquid on the target And evenness, make the liquid utilization rate of 30% or more. The distribution of the droplets on the fruit trees is mainly affected by the wind speed of the orchard wind-fed sprayer, and the wind speed of the wind turbine is mainly determined by the amount of wind. In this paper, by changing the air volume of the fan, the effect of the variation of wind speed in the canopy on the amount of pesticides deposited on the target was discussed. The penetrability and deposition of the droplets in the canopy were positively correlated with the wind speed
