我省农村家家户户都有存粮,给老鼠的生存和繁殖提供了有利条件;加之,生态环境变化,鼠类适应性广,繁殖力强等原因,致使农田害鼠数量猛增,有些地方农田害鼠的危害程度已超过农作物病虫的危害。据不完全统计:全省年发生鼠害面积达2800万亩左右。1982年全省因鼠害损失粮食10亿公斤。1983年虽经积极防除鼠害,粮食损失仍达6.5亿公斤。为安全、经济、有效地控制鼠害,我们在全省三十二个县比较系统地开展了鼠情观察、测报和防除试验示范。初步摸清我省农田害鼠
In rural areas, every household in our province has stored grain, which provides favorable conditions for the survival and reproduction of mice. In addition, due to changes in ecological environment, extensive adaptability of rodents and strong reproductive capacity, the number of pest rats in farmland soars. In some places, The degree of harm has exceeded the hazards of crop pests. According to incomplete statistics, the annual area of rodent pests in the province is about 28 million mu. In 1982, the province lost 1 billion kilograms of grain due to rodent pests. Despite the active control of rodent pests in 1983, food losses still amounted to 650 million kilograms. In order to control the rodent pests safely, economically and effectively, we carried out the observation and measurement of rodents and the demonstration of control measures in the 32 counties throughout the province. Preliminary find out our province farm rat
