| 摘 要： | 通过0cm、5cm、10cm和15cm四个不同刈割留茬高度的试验处理，对“黑土滩”上建植的混播人工草地群落结构及生产力进行了研究，结果表明：随着留茬高度的降低，人工草地混播群落中垂穗披碱草和中华羊茅成为减少种，早熟禾则为增加种，西伯利亚蓼成为侵入种；人工草地优良牧草垂穗披碱草和中华羊茅在群落生物量中所占的比例呈下降趋势。因此，适宜的刈割留茬高度可保持“黑土滩”混播人工草地的群落稳定性和草地生产力。

| Abstract: | The community and the productivity of artificial miking seeded grassland in "the black soil type" were investigated at 0 cm,5 cm,10 cm and 15 cm after being mowed.The results showed that Elymusnutans and Festuca sinensis decreased,but poa spp.increased and polygonum sihiricum increased in the community.The biomass propotion of fine forage,Elymusnutans and Festuca sinensis,in the artifical grassland in the community dropped along with increasing of mowing high.The artificial vegetation community tended gradually to stablity and come to the top vegetation community finally along with keeping stubble high increasing progressively. |
