前言使用常量喷雾技术喷撒农药,用水量大、工效低,在大面积成片的茶园中,常不能在短期内及时完成治虫工作,以致错过防治适期。使用手持式电动超低容量喷雾器,用水量少,工效高,可以在较短时间内完成治虫工作。我们于1988年从江西九江县电动喷雾器厂引进了手持式电动超低容量喷雾器治虫,对农药在茶园中的药效进行了试验。 Preface The use of constant spray technology spraying pesticides, water consumption, low efficiency, in a large area into a tea plantation, often in a short period of time to complete pest control work, resulting in missed control period. The use of handheld electric ultra-low volume sprayer, less water, high efficiency, can be completed in a relatively short period of time pest control. We in 1988 from Jiujiang County, Jiangxi Electric Sprayer Factory introduced a portable ultra-low-volume electric sprayer pest control of pesticide efficacy in the tea plant were tested.
