会宁是甘肃省定西专区的一个县,全县人口约23万人,总面积7,350平方公里,气候干燥,加之过去地广人稀,荒地面积较大,致使田鼠大量繁殖。这些鼠不但危害人体健康,而且破坏农业、牧业、林业生产和水土保持土作仅就农业来讲,损失是非常严重的,如1954年土木岘乡安坡社种的14亩糜子;1956年杨岘社种的36亩胡麻,1957年种的27亩荞麦;四方乡南坡社的250亩荞麦等,均因遭受各种鼠类破坏而毫无收成。解放前鼠害更为猖鳜,如1930年大沟乡的孟昌泰,只靠挖鼠仓所得粮食就渡了两个荒年;河畔乡杨中海挖出粮食1,500斤;朱海林曾挖出糜子和谷子1, 400斤,象这种例
Ning would be a prefecture in Dingxi Prefecture, Gansu Province. The population of the county is about 230,000 with a total area of 7,350 square kilometers and a dry climate. In the past, the territory was sparsely populated and the wasteland was large, causing the voles to multiply in large numbers. These mice not only endanger human health, but also damage agriculture, animal husbandry, forestry production and soil and water conservation. In terms of agriculture alone, the loss is very serious. For example, in 1954, 36 hectares of flax cultivated by Yang Hyang Society, 27 acres of buckwheat planted in 1957, and 250 acres of buckwheat grown in Southern Slope Township in Sifang County are all suffering from various types of rodents without any harvest. Before the liberation of rodent pests more rampant, such as 1930 Dagou Township Mengchang Tai, relying solely on the food from digging rat warehouse crossed the two barren lands; Riverside Township Yang Zhonghai digging 1,500 pounds of grain; Zhu Hailin had dug out the millet and Millet 1, 400 pounds, like this example
