我们公社西坂大队试制了几种行之有效的专灭蚊绳的药方,现介绍如下,供各地参考.一、摘锯树叶(各地都有)五斤,捣烂,加开水十至二十斤浸泡六至十二小时.同时,每斤浸泡液加清水三斤,把这种药液喷于粪池内,灭蛆效率达100%,并能保持八至十天不生蛆.用来灭孑孓时,应先去渣取其药液,每斤滴煤油十至二十滴,喷至污水表面,可获同样效果. Our commune Xiqiao Brigade has trial-produced several effective remedies for the exclusive mosquito-killing ropes, which are introduced here for reference. First, picking saw leaves (everywhere there are) five pounds, smashed, adding boiling water to ten to twenty pounds Soaking for six to twelve hours. At the same time, add three pounds of water per kilogram soaking solution, spray this liquid in the dung, the efficiency of scorpion smashing up to 100%, and can maintain eight to ten days without scorpion. When you should, you should first go to the slag to take its liquid, ten to twenty drops of kelp per drop of kerosene, sprayed to the surface of the sewage, can get the same effect.
