手动喷雾器WS-16型的性能及在棉蚜防治中的应用

The capability of new sprayer WS-16 and its application in control of aphides in cotton fields

新型手动喷雾器WS 16型的额定流量和喷出的药液附着率分别比工农 16型提高35%和10%以上;用于防治棉花蚜虫,WS 16型喷雾器的两种喷头的防效都极显著优于工农 16型切向喷头,且工效提高25%以上;在应用中还表现出省力、不渗漏、药液利用率高等特点,具有推广价值。

The objective of the study reported here was to compare the capability and technical indices of new sprayer WS-16 with that of the older sprayer Gongnong-16 in controlling aphides in cotton field. The results indicated that rated flow capacity and adhering rates of insecticide liquids sprayed by new sprayer WS-16 were more than 35% and 10% higher than those by sprayer Gongnong-16, respectively. The efficiency of controlling cotton aphides for two kinds of spraying jets supplied for sprayer WS-16 was significant higher than that supplied for sprayer Gongnong-16. The working efficiency of spraying WS-16 was increased by more than 25% compared with one of spraying Gongnong-16.The new sprayer WS-16 has following advantages such as saving labor, without percolating of insecticide liquids, and high efficiency. Therefore, it could be widely used to control aphides in cotton field.
