走廊微环境差异对墙面绿化金边吊兰生长的影响

Growth of Chlorophytum comosum at Metope Greening of Hallway in Xi′an

以金边吊兰为试材,研究了金边吊兰在西安走廊墙面绿化中的生长状况,对叶长宽比、干物质含量、叶尖枯死部分长度和比例进行比较分析。结果表明:当光照强度低于2 132lx(晴天)/560lx(阴雨天)时,金边吊兰表现出明显的徒长和叶片枯死症状;处在走廊通道处的区域光照最弱,但金边吊兰的长势却优于光照较强的临近区域,表明通风能够在一定程度缓解弱光对植物造成的伤害。

Taking the Chlorophytum comosum as material, the growth of them at metope greening of hallway were studied in Xi＇an by comparing the ratio of leaves length to width, dry matter content, the length of die tips and ratio of leaves. The results showed that Chlorophyturn comosum grew excessively and a large number of die tips appeared while the illumination intensity was below 2 132 lx on sunny days or 560 lx on rainy days. In the area nearby the passageway where the illumination intensity was the most weak, but the plant grew better than the adjacent where the light was intenser, which suggested the circulate air could lessen the harm from weak light.
