| 摘 要： | 在高原鼠兔中等危害的高寒草甸草地上，用1cm孔径的网片围笼隔离害鼠，再用常规围栏隔离家畜进行测产试验，结果表明：A处理（无害鼠无家畜）的总产草产量、可食牧草产量均高于B处理（有害鼠无家畜），经t检验。产草量、可食牧草量差异极显著（P＜0．01）；B处理的不食毒杂草占总产草量的比率高出A处理7.14个百分点；证明高原鼠兔对高寒草甸草地牧草生长有抑制作用，同时对草群结构也有影响。

| Abstract: | A trial was conducted on medium pika infested meadow pasture. The pasture was caged by net with lcm holes to prevent pika,and by normal fence to prevent livestock, The result showed that forage yield,editable forage yield on A treatrment (free of pika and live stock) were better than B treatment,The result of test indicated that difference between A and B on forage yield and editable forage yield were significant(P<0. 01). poison weeds took account for 7.14%more in B than A. It is indicated that pika has apparently suppressed growth of forage,and has impact on structure of vegetable. |
