摘  要:
分析研究了适合亚热带地区的10种鸢尾属观赏地被植物的生态特性与景观效果,结果表明,在中国亚热带地区,鸢尾属种类可划分为冬春功能群和夏季功能群两大类,其中鸢尾、蝴蝶花和德国鸢尾适合春季观赏,其余种类适合在春夏观赏;在春季,溪荪的光合速率最高,德国鸢尾和黄菖蒲次之,蓝蝴蝶花和白蝴蝶花最低;蒸腾速率的顺序也为溪荪最高,蓝蝴蝶花和白蝴蝶花最低;德国鸢尾由于相对较高的光合速率和相对较低的蒸腾速率,水分利用效率最高,花菖蒲则因相对较高的蒸腾速率和相对较低的光合速率,水分利用效率最低。

摘  要:
Analysis on ecological properties and ornamental effect of 10 Iris species at subtropical areas in China demon- strated that Iris could be divided into two functional types: winter & spring, summer. Among then, I. tectorum, I. japonica and I. germanica had the best effect in spring, and the left in spring and summer. I. sanguinea had the highest photosynthe- tic rates in summer, then I. germanica, the last was I. tectorum and I. japonica var. pallescens, while transpiration rate had the same result. Because of relative higher photosynthetic rates and lower transpiration rate, I. germanica had the most effective moisture application, while I. ensata var. hortensis the less.
