| 摘 要： | 在红池坝人工草地对放牧方式和放牧强度进行比较研究,同时对已给定的载畜量加以验证,以便制定该草地的最适放牧制度。研究结果表明,适于该地区的放牧管理制度是划区轮牧;各个阶段的载畜量与牧草生长速度之间的关系可用数学模型表示为:Y=179.5＋5.48X,在每公顷7.5个绵羊单位的载畜量下进行中度放牧强度可获得草地最大产草量,并保持其稳定。

| Abstract: | The comparison experiments on grazing pattern and grazing intensity were conducted on the pasture at Hong Chi Ba farm. At the same time, the animal carrying capacity given was checked by the mathemative model of grazing system.The results showed that the pasture in the area should be grazed in regular succession. The relationship bettween stocking rate and growth rate of herbage at each stage could be expressed by the following regressive model:Y = 179. 5 + 5.48XThe 7. 5-sheep-unit-stocking-rate grazing could obtain the maximum yield of herbage and keep the pasture steady. |
