【摘要】 通过野外模拟周调节水库消落带水位变化研究,表明单种蓉草前期及冬季生长和繁殖受抑制影响明显,呈现下降—逐渐稳定—趋于回升的趋势;与香根草混植的蓉草的叶长、叶宽、成活率及覆盖率等均优于单种的蓉草,可推荐作为周调节水库消落带植被恢复的植物组合。更多还原

【Abstract】 This study simulated water level variation in buffer zone of weekly regulating reservoir,and found that the growth and reproduction of single planted Leersia oryzoides was inhibited significantly in the early stage and winter,but it can gradually stabilize and tend to rise.The index(including leaf length,leaf width,survival rate,coverage) of Leersia oryzoides which was mixed planted with vetiver were better than that of single planting.So the mixed planting of Leersia oryzoides and vetiver can be recommended for vegetation restoration in buffer zone of weekly regulation reservoirs.更多还原
