摘　　要：亚热带中、高海拔地区放牧人工草地牧草生长速率呈单峰曲线 ,高峰落在 7月份 ,低谷为 3～ 4月份 ,10月至第二年 3月间为牧草低生长速率期 ,牧草生长速率起伏不定。在速生季 ,中海拔地区牧草生长速率较高海拔地区高 。Pasture growth pattern in the mid high attitude area in the Yunnan (PRC)subtropical zone showed one peak in July and lowest growth in March-April. Pasture growth is lower from October to March. Pasture growth rate is higher in mid attitude area than in high attitude area during raining, high growth season, but shows no difference in the low growth period.

关 键 词：人工草地 牧草生长 产草量 季节动态
