淳安县地处浙西丘陵山区,地貌复杂,作物多样,对老鼠的生长繁育十分有利。近几年来,由于生态失调,捕食害鼠的黄鼠狼家猫等减少,老鼠数量激增,危害猖獗。1985年全县农田鼠害发生面积4.5万亩,损失粮食20万余公斤,占病、虫、草、鼠“四害”总损失值的15％,已成为主要的减产因素。为了更好地指导农户开展农田灭鼠,我们于1986年4、5、9、10月分别进行农田鼠情调查及大田防治技术探讨,现将结果小结如下:
Chun’an County is located in the hilly area of western Zhejiang, with complex topography and diverse crops, which is very beneficial to the growth and reproduction of mice. In recent years, due to ecological disorders, the reduction of weasels, cats and other predators, the surge in the number of rats and the dangers of rampant. In 1985, 45,000 mu of farmland rat rodento occurred in the county, with the loss of more than 200,000 kilograms of grain, accounting for 15% of the total losses of “four pests” of disease, insects, grasses and rats. It has become a major factor in yield reduction. In order to better guide farmers to carry out farmland rodent control in April, May, September and October 1986 respectively, farmland rodent investigation and field control technology, the results are summarized as follows:
