摘要
研究了亚热带中山地区草地不同放牧强度与草地植物产量和放牧家畜生产性能之间的关系,试验结果表明,不同放牧强度对草地植物产量和放牧家畜生产性能的影响不同。在A组放牧强度的载畜量水平,草地植物利用率高,植物产量和畜产品产量低;在C组放牧强度的载畜量水平,草地植物利用率低,老草残留,植物再生力降低;在B组放牧强度的载畜量水平,草地植物的利用率为60～70％,对植物生长和利用有利。
ABSTRACT The relations between grazing intensity, yield of pasture and the animal production in mountain of sub-tropic were investigated. The results indicated that the effects of the grazing intensity on the yield of pasture and the animal productivities were different. Under the A group grazing intensity, the stocking rate and pas-ture utilization was higher, but the yield of pasture and animal productivities were lower. Under the C treat-ment, the stocking rate and the plant utilization was lower, residuse of senescent grasses increased and regene-ration capacity of plants decreased. The plant utilization was about 60～70% under the B treatment. It seems that the B treatment is suitable or the growth and utilization of pasture.
