| 摘 要： | 通过种植密度对皇草植被恢复速度的影响研究,结果表明:随着栽植密度的加大,皇草植被恢复速度加快。处理2500株/667m2恢复植被盖度达90%以上只需2个月,产草量达134331.0kg/hm2。从经济角度出发,采用皇草进行植被恢复和刈割利用,以栽植22500～30000株/hm2较为适宜。

| Abstract: | The influence of planting density on recovering speed of Keen grass vegetation was studied. The resultshowed:The speed of keen grass recovering vegetation was accelerating with increasing of the planting density. Thevegetation coverage could reach 90% with the plantingdensityof2 500 plant /667m2 onlytwomonth. The fresh grass yieldcan reach 134 331.0 kg/hm2. The plantingdensityof22 500～30 000 plant/hm2was suitable and economical when the keengrass was used torecover vegetation and cut grass. |
