| 摘 要： | 放牧强度和放牧制度影响牧草贮藏养分及草地早春生产力。全年禁牧、轻度放牧和中度放牧牧草贮藏养分及草地早春生产力较高；重度放牧两者均最低；夏秋季节放牧较冬春季节放牧低。划区轮牧与同等放牧强度的中度放牧相比牧草可贮藏更多的养分，而且草地具有较高的早春生产力。

| Abstract: | Herbage nutrient storage and early spring productivity are influenced by grazing intesities andsystems. Herbage nutrient storage and early spring productivity are higher in non-grazing,lightgrazing and intermediate grazing treatment than in heavy grazing treatment. Herbage nutrient storageand early spring productivity are lower in warm season grazing treatmint than in ccol season grazingtreatment.In the same intermediate grazing level rotational grazing has higher herbage nutrient storageand early spring produtivity than fixed grazing. |
