中华鼢鼠在甘肃干旱山原区密度大,危害严重。由于其终年营地下生活,鼠洞除用于栖息、蛰眠外,还是其避敌、觅食、求偶繁育的场所,摸清其洞道结构是研究探讨综合防治的前提。为此我们在1988—1989年选了草甸地、苜蓿地及小麦、马铃薯、胡麻、玉米等各种不同地块的作物,采取挖掘鼠洞的调查方法,共挖鼠洞277个,总结归纳如下。1 中华鼢鼠洞道分布状况 中华鼢鼠洞道分布在土层5cm以下,主
Chinese zokor in the dry plains in Gansu Province density, serious harm. Because of its life all the year round, the rat hole is not only used for habitat and dormancy, but also for its place of refuge, foraging and courtship breeding. To find out the structure of its tunnel is the prerequisite for the study of comprehensive prevention and control. To this end, we selected crops from meadow, alfalfa, wheat, potato, flax, corn and other land plots in 1988-1989. A total of 277 holes were excavated, and the results were summarized as follows. 1 Chinese zokor tunnel distribution Chinese zokor tunnel distribution in the soil below 5cm, the main
