从70年代末以来,关岭县鼠害一直十分严重。如1981年春播的玉米12万亩,因害鼠盗食种子,有5万多亩需补种,3100多亩重播1～2次,增加用种量达52.85％。1985年春季,顶云乡有100多亩蚕豆和白菜被老鼠咬窃取食造成无收。据统计,几年来因鼠害损失的粮食,约占当年总产量的11％。为了探讨防治对策,对当地优势鼠种黄胸鼠(Rattus,flavipectus)进行生态观察.在全国农田鼠害数量预测预报研究协作组统一安排下,我们于1984
Since the late 1970s, rodents have been very serious in Guanling County. For example, in spring of 1981, 120,000 mu of corn was sown due to pest feeding on rats and more than 50,000 mu were replanted. 3100 mu of land were replanted 1 or 2 times, and the seedlings increased by 52.85%. The spring of 1985, Top Cloud Township, more than 100 acres of beans and cabbage was bite theft caused by rats eatless. According to statistics, the loss of food due to rodent pests in recent years accounts for about 11% of the total output of that year. In order to explore the countermeasures for prevention and treatment, the ecological observation was carried out on the Rattus flavipectus, a dominant species of rodents in our country.Under the unified arrangement of the collaborative group on the prediction of the number of rodents on farmland in our country,
