近年来,由于天气干旱,有利鼠类繁殖及捕杀鼠类天敌等原因,使鼠害普遍发生,特别是田鼠为害严重,给农业生产带来很大损失。灭杀田鼠的药物很多,效果较好的有以下三种: 一、磷化铝片剂。采用磷化铝片剂直接投入洞内,每洞投药3.3克(一片),之后将洞口填实,42小时即可生效,杀鼠率达96％以上,既经济又实用。此种药剂为剧毒熏蒸剂,应严格按技术操作规程进行,严禁家庭内灭鼠使用。二、磷化锌。磷化锌为黑色粉末,对鼠类有极强的毒力,田鼠吃后,因药物与胃酸起作用而中毒,一般3-10小时即可死亡。毒饵配制方法是:磷化锌30-50克用料1公斤(小麦、豆饼糁、玉米糁、花生糁等食物)混合均匀,再加香油1两左右,以增加香味,然后拌匀,即成3-5％磷化锌毒饵。三、敌鼠钠盐。敌鼠钠盐为蛋白色粉末,稳定性强,田鼠吃下中毒,产生缺氧而死亡。因此,大部分田鼠死在洞外。此药具有对人畜毒性低,对鼠 In recent years, the occurrence of rodent pests is widespread because of the arid weather, the favorable breeding of rodents and the killing of rodent natural enemies. In particular, the rodents are seriously devastated and cause great losses to agricultural production. Vomit vomiting a lot of drugs, the better the following three: First, aluminum phosphide tablets. The use of aluminum phosphide tablets directly into the hole, each hole dosing 3.3 grams (one), after filling the hole, 42 hours to take effect, killing rate of 96% or more, both economical and practical. Such agents are highly toxic fumigants, should be strictly in accordance with technical procedures, to eliminate the use of domestic rats. Second, zinc phosphide. Zinc phosphide is a black powder that is extremely virulent to mice. After eating a vole, it is poisoned by drugs and gastric acid, and can usually die from 3 to 10 hours. Bait preparation method is: zinc phosphide 30-50 grams of material 1 kg (wheat, bean cake 糁, corn 糁, peanut 糁 and other food) mixed, together with sesame oil about one or two, in order to increase the flavor, and then mix, Serve 3-5% zinc phosphide poison bait. Third, the enemy mouse sodium. Diparmic sodium salt as protein powder, strong stability, voles poisoning, hypoxia and death. As a result, most voles die outside the hole. This medicine has low toxicity to humans and animals, to rats
