摘要
1986—1990年在陕西、山西两省进行了甘肃鼢鼠和中华鼢鼠综合防治的研究。在化学防治基础上,采取加强农田基本建设蓄积天然降水、作物轮作倒茬、使用化学除草剂铲除田间杂草等生态措施进行综合防治。结果表明,药物灭鼠可迅速将害鼠密度降至防治阈值(3.1只/公顷)以下,其他几项生态措施对害鼠种群数量恢复亦有一定抑制作用,避免了连年使用化学药物防治的弊端。
Gansu zokor and Chinese zokor are the chief pest rodents in theagricultural area of loess plateau.From 1986 to 1989,the authors stu-died the integrated control of Gansu zokor and Chinese zokor at twoexperimental points in Shaanxi and Shanxi Provinces.On the basis ofusing rat-poison to control zokors,a series of ecological measures tocontrol the rodents were investigated,including strengthening the cap-ital construction on farmland to preserve rain water,crop rotation,weed eradication to worsen the living conditions of rodents.The resultsshowed that the rat-poison can obviously decrease the population dens-ity of these two zokors under the economic threshold of control(3.1zokors/per hactare).The ecological measures can delay the populationrecovery of zokors,
