WS—Ⅰ型手提超低容量喷雾机(以下简称WS—Ⅰ型机),是一种小型轻便机动喷雾机,净重7.5公斤,有效射程15米。具有体积小,重量轻、工效高、携带方便等特点。目前在国内卫生防疫中和大田作物上普遍使用,而果树病虫防治方面尚未见报道。为此,1984年在本所江津实验场台地和平坝甜橙果园,对树高2—3米,株行距2×3米的10年生树,用WS—Ⅰ型机与高压机动喷雾器和手压单管喷雾器防治柑桔潜叶蛾进行了对比试验。
WS-Ⅰ portable ultra-low volume spray machine (hereinafter referred to as WS-Ⅰ-type machine), is a small lightweight mobile sprayer, net weight 7.5 kg, the effective range of 15 meters. With small size, light weight, high efficiency, easy to carry and so on. Currently in the domestic epidemic prevention and field crops in general use, and fruit pest control has not been reported.
