摘要： 通过放牧试验,对决定畜牧业生产效率的放牧管理体系的主要因子(绵羊品种,载畜量和放牧制度)进行评价和研究。结果表明,适合于红池坝人工草地的放牧绵羊品种为内蒙古中国美利奴羊;放牧方法为划区轮牧;载畜量为7.5个绵羊单位/公顷;各个牧草生长阶段的放牧强度为:Y＝179.5+5.48×(为牧草生长速度);放牧小区面积、割草小区面积与机动小区面积的百分比组成为66.7:20:13.3;不适放牧起止时间为:一年内当月均气温处于1.3～6.7℃和12～8℃的日子。

Abstract: A set of grazing experiments were conducled to evaluate the grazing management system which is mainly influenced by sheep species, stocking rates and grazing reginles.The research results showed that the Chi nese Merino from Inner Mongolia is more suitable for feeding on Hongchiba sown pasture than XinJiang sheep: the rotational grazing is required: the stocking rate must be 7.5 sheep Units/ha; the grazing severlty in each time peried can be calculated by: y = 179.5 + 5.48×(X represent current pasture growth rate); the ratio of area for grazing and cutting and buffering is about 66.7:20:13.3; when the monthly mean temperature varies from 1.3 to 6℃ or 8 to 12℃, the pasture is no suitable for grazing.
