防治森林病虫害喷喷雾技术的选择病虫害防治的成败与施药方式与设备有很大关系。喷雾技术的选用取决于很多因素,如植物的类型、病虫害的种类、危害程度、农药类型、取水条件、防治区通行条件等。常用的喷药技术有常量喷雾、超低量链喷雾、静电喷雾等。常量喷雾:有针对性地把药液直接喷到需要防治的目的物上。为避免药害,需用大量水将药液稀释,单位面积上的施药量很大,工效比较低。超低量喷雾:与常量喷雾相比,一是使用超低量喷雾器,每小时可防治1公顷--6.7公顷,比背负常量喷容器工效高30倍以上。二是由于雾粒很小,飘移面积大,与常量喷雾比较,可节省10%--30%的用药量。三是超低量喷施的适油剂,药液的透性和耐雨水冲刷能力较常量喷施的乳状液强。同时由于飘移分布均匀,使林木的各部位都能沾上药液,因此杀虫灭菌效果好。四是使用超低量喷雾机比用背负手动喷雾器可节省50%--90%的防治费用。五是不用水(或只用很少量水),省去配药运水的繁重劳动,特别是在干旱地区和山区更为适宜。超低量喷雾也存在一定的局限性,因雾粒小,喷雾时易受风力、风向和上升气流等气象条件的影响,需要一定的农药剂型,剧毒农药不能用,使用条件和技术要求较严格。静电喷雾:常规喷雾法,总要流失一部分农药,既不能发挥最大药效,又浪费人力物力,还造成污染。超低量喷雾法,虽提高了喷洒效果,但也容易受气流影响,而不能发挥最高药效。静电喷雾法的喷洒效果,在一定程度上得到了进一步的改进。目前国内外都在加快静电喷雾技术的研究开发。静电喷雾的优点,一是药液雾粒直径属于超低量范围(15微米--75微米)。由于雾粒带电,吸附力强,所以农药利用率比超低量喷雾高,用药量少,既节约农药,又减少污染。二是因雾粒带同性电荷,在空间飘移时相互排斥,不发生凝聚现象,覆盖均匀,同时受目的物周围电力线的作用,能吸附于目的物的正、反面,杀虫效果好。三是雾粒吸附于目的物表面比较牢固,不易被气流飘失或雨水冲刷流失。适用于有导电性的农药制剂。但静电喷雾需要能产生直流高压的静电设备,因此,结构比较复杂,成本较高。目前较常用的施药设备是背负式喷雾器,在使用背负式喷雾器时应注意:1.喷雾时步行速度应均匀,不可快慢不均,而且喷头应上下摆动,避免雾滴出现过密或过稀现象。雾滴过密会造成药害,过稀则影响防治效果。喷高树时,喷管可垂直固定向上喷雾。因喷管垂直,流量减少,为达到一定的雾滴密度,步行速度可适当减慢,并应注意药箱内的药液量不能少于1/4箱。2.喷雾时,要注意风速和风向的变化,如果其变化的程度已不适应原定的行走方向和喷幅时,应在原地停止喷雾,等待合适的风速和风向或改变喷向或喷幅后再进行作业。3.喷雾作业时要避免喷头碰到树干、作物或其他硬物上,禁止喷头平放在地面上就起动发动机。4.风向与走向的夹角小于45度及风速大于每秒5米时不宜进行超低量喷雾。在防治树高5米以上的树时,风速不得超过每秒3米。5.背负式喷雾机要适时进行技术保养。每天作业后,应将药箱的药液排除,用柴油清洗药箱、药箱盖、输药管、手把开关和流量阀,保证药路畅通。超低容量喷头应3天保养1次,主要是清洗轴承和加新润滑脂(加入1号二硫化钼润滑脂后,再加入2滴--3滴机油)。存放时,应清洗和检查喷头所有零件,轴承涂上防锈油,用纸包好,存放在阴干的地方。(来源:黑龙江林业第8期)
