野生结缕草耐践踏性综合评价
【目的】研究野生结缕草被践踏后的综合表现,探索其作为运动场草坪和游憩草坪的开发价值。【方法】以目前湖南省常用的草坪草杂交狗牙根为对照,研究不同践踏强度对野生结缕草和杂交狗牙根外观质量(色泽、盖度、密度、质地、均一性)、生长发育(生物量和植株高度相对生长率)和生理代谢(叶片相对含水量、质膜相对透性、根系活力、可溶性糖含量)的影响。【结果】不同践踏处理下野生结缕草的盖度、叶片宽度、密度、均一性、地上/地下生物量、叶片相对含水量、根系活力等8项指标的均值大于杂交狗牙根,而叶绿素含量、株高相对生长率、叶片细胞伤害率、可溶性糖含量等4项指标的均值小于杂交狗牙根。【结论】野生结缕草具有较强的耐践踏性,适于...
