我区地处云南西南部。近年来,因自然条件和生态条件改变等原因,农田鼠害发生严重,每年发生达35—40万亩,占全区耕地面积的10%以上,损失粮食(田间)达5000吨以上,有的地方鼠害造成的损失已超过病虫草害。为了提高农田鼠害的综合治理效果,我站从1989年6月开始,在凤庆、云县、耿马和临沧等地建立了鼠情监测点,逐月开展田间鼠情调查,对农田害鼠变化规律进行了初步探讨。现初报如下:1 监测方法结合我区的地理环境和作物布局,设4个常年监测点,各监测点定人、定时、定点、定
My area is located in southwestern Yunnan. In recent years, because of the change of natural conditions and ecological conditions, the incidence of farmland rodent pests is very serious, accounting for 35-40 mu of land per year, accounting for more than 10% of the cultivated land area in the region, losing more than 5,000 tons of grain (field), and some The losses caused by local rodent pests have more than pests and diseases. In order to improve the comprehensive control effect of farmland rodent pests, we started to set up rodent monitoring points in Fengqing, Yunxian, Gengma and Lincang provinces in June 1989 and carry out field rodent surveys on a monthly basis. The changes of pest rats were preliminarily discussed. The first report is as follows: 1 monitoring methods combined with the geographical environment and crop layout in my area, set up four perennial monitoring points, the monitoring points set, regular, fixed, fixed
