3种滨水花卉植物的水分适应性研究

为选择适宜滨岸区域水旱交替生境条件的植物,研究了干旱和水涝对3种滨水花卉植物千屈菜、黄菖蒲、毛茛生长的影响。结果表明,黄菖蒲对水分的适应范围最宽,既喜水湿又耐干旱;千屈菜更喜欢水湿环境;毛茛不耐干旱。在园林中应用时,临水种植千屈菜更有利于其生长,毛茛不宜种植在距水较远的地段,而黄菖蒲可以种植在浅水到岸坡较广阔的范围内。

Study on Water Adaptation Characteristics of Three Waterfront Flower Plants

In order to choose plants which would be suitable wet-dry-alternating condition , influence of drought and the waterlogged treatments on growth of three waterfront flower plants, Ranunculus japonicus Thunb., Lythrum salicaria Linn. and Iris pseudacorus L. was studied. The results showed that I. pseudacorus not only liked wet but also could tolerant drought with the widest water adaptation range. L. salicaria prefered wet condition. R. japonicus could not tolerant drought. When they were used in landscape, it＇s better to plant L. salicaria in waterfront, R. japonicus not far from the water and 1. pseudacorus in wider region from shallow water to the slope.
