对于用弥雾机给果树打药这个问题回答各说不一,包括我们烟台这边的果农也对使用弥雾机褒贬不一,针对这个问题,我走访了几位果农,他们普遍反映,用弥雾机给果树打药效果比用别的喷雾式打药效果要好很多,其中,我的一位朋友叫王伟新,他的弥雾机叫"一桶油打六箱波尔多液",一听这名字,就说明他的弥雾机应该是质量最好、用途最广、效果最突出的,他家苹果多数被商家早早预订。根据这些情况,下面我从两个方面对弥雾机打药做一阐述。
一、用弥雾机给果树打药的五个优点。
第一个优点是落药点均匀。弥雾机喷雾后形成的药物颗粒仅有0.5微米,在空气中可以完全弥漫起来,保证果树的叶片正反两面都能落药,能够实现打药均匀、彻底,不留死角。
第二个优点是杀菌杀虫彻底。由于弥雾机打药实现了无空隙、立体式、全面化,病菌和害虫无藏身之处,杀菌杀虫彻底,对病虫害的防治效果显而易见。实践证明,使用弥雾机打药比普通喷雾器打药的苹果标光要高上一个档次。
第三个优点是省工省力。一亩地苹果树用普通喷雾器打药需要两到三个小时,而用弥雾机用不了半个小时,缩短作业时间,提高工作效率。
第四个优点是可以避开高温作业。果树打药的时间正值气温升高,使用弥雾机需要在凌晨三四点钟作业,可以避开高温,保证安全。
第五个优点是用药量减少。由于弥雾机呈雾状弥漫,农药的利用率提高,农药用量仅需普通喷雾器的三分之一,这样的苹果药残少,符合食品安全要求。
二、使用弥雾机感觉效果不好的三个原因。
一是生产弥雾机的厂家质量不过关。有些不良商家生产加工技术落后,或者偷工减料,生产的弥雾机不合标准,并且以次充好,高价销售,欺果农。
二是销售弥雾机的商家服务不到位。这部分商家不懂弥雾机的构造原理,仅仅以卖货挣钱为主,没有做好售后服务,果农不会正确使用,造成打药效果不好。
三是经营农药的店铺配药不合理。由于不懂弥雾机打药用量,一些经营农药的店铺在销售农药时,按照普通喷雾器的用量配药,造成用药过多,对苹果造成损害。
以上所述:用弥雾机打药,只要购买到正宗的产品、把握好农药的剂量、掌握好打药的时间、做好个人的安全防护,其效果应该远远高于其他喷雾器。
