摘要
研究了青海冷地早熟禾(Poa crymophila cv.Qinghai)在青藏高寒地区的生长状况,结果表明:青海冷地早熟禾的生长速度在生育期内呈升-降-升的趋势;植株高度与生物量呈"S"型曲线;而草层生物量随高度的增加呈下降趋势。
The growth condition of Poa crymophila cv. Qinghai in the alpine region were studied. The results showed that： growth rate of Poa crymophila cv. Qinghai in growth period present up-down-up trend; plant height and biomass manifested ＂ S＂ shaped curve ; whereas the grass layer biomass increased with height decreased.
