近年来,随着仓内单面封储粮技术的推广和应用,在熏蒸治虫时逐步由整仓投药改为薄膜密封的粮堆内授药,而对薄膜外仓内空间的害虫则以加强清洁卫生工作予以清除,此法虽简便易行,但除虫不彻底,对高空特别是顶棚瓦面的潜伏性害虫的清除则较困难。为了有效地消灭仓内空间所有部位的害虫,进一步巩固单面封的储粮效果和“四无粮仓”的质量,我们曾于去年进行了敌敌畏加热雾化熏杀仓内空间害虫的试验,今年我们又作了改进,这种雾化器安全可靠,效果良好。现将试验的情况简述如下。
In recent years, with the promotion and application of single grain storage and grain storage technology within the warehouse, pesticides gradually changed from the whole warehouse to the film-sealed foodstuffs for pesticide administration while the pest in the space outside the film warehouse was strengthened Cleaning and sanitation work is to be carried out. Although this method is simple and convenient, it is difficult to remove insects and eliminate the latent pests on the roof, especially on the roof tiles. In order to effectively eliminate pests in all parts of the storage space and further consolidate the storage effect of single-sided seals and the quality of “No-no-no-granary”, we conducted a trial of heated atomization and fumigation of space-borne pests in the warehouse last year. We made another improvement, this nebulizer safe and reliable, good effect. Now test the situation is summarized as follows.
