- 摘要:
- 以鹅绒委陵菜为试材，采用人工践踏的方式研究了不同践踏强度对鹅绒委陵菜地上部生长的影响。结果表明：践踏对鹅绒委陵菜草坪的表观质量产生较大影响，随着践踏生长期的延长，在中度和重度践踏下，致使鹅绒委陵菜草坪高度、密度、均一性和表观形质地下降；对其基株的复叶数和长度、匍匐茎的数量和长度、地上和地下生物量，随着践踏强度的加强呈下降趋势，而匍匐茎的茎粗大小不受其影响；同时鹅绒委陵菜草坪的反弹系数、滚动摩擦距离随着不同践踏强度的加强，而呈增大的趋势。
- Abstract:
- Taking Potentilla anserina L.as test material，the effect of different trampling intensities on the overground part growth of Potentilla anserina L. were studied by using artificial trampling.The results showed that there was significant impact on apparent quality of the lawn of Potentilla anserina L.with the prolong of growing season，The height，density，uniformity and apparent quality of Potentilla anserina L. were decreased under the condition of moderate and severe degree of trample.With the strengthening of trampling intensity，the diameter of stolon had not changed，the number and length of stolon and compound leaf of stock plant and the above and below ground biomass were decreased.Rebound coefficient and rolling friction distance of the lawn of Potentilla anserina L. were increased with the strengthening of trampling intensity.
