| 摘 要： | 以长沙地区现有水生植物就观赏性进行调查分析,采集黄菖蒲、荸荠、海寿花、绶草进行50 d的观察测定,分析这4种水生植物对供试水体的色度,含氧量,以及氮、磷含量的影响。结果表明:4种水生植物水体中DO的含量为荸荠>绶草>黄菖蒲>海寿花;水体浊度为绶草>荸荠>黄菖蒲>海寿花;水中TP含量为绶草>黄菖蒲>海寿花>荸荠;水中TN含量为绶草>荸荠>海寿花>黄菖蒲。种植4种水生植物的水体pH值在7.5~8.5之间。黄菖蒲和海寿花的长势比另外两种植物的好,海寿花水体浊度最低,景观效果最明显。

| Abstract: | The investigations on the ornamental value of the existing aquatic plants were carried out.By gathering Pontederia cordata,Eleocharis dulcis,Iris pseudacorus,Spianthes aristotelia,observing and testing for 50 days,the effects of four aquatic plants on chromaticity,oxygen levels,nitrogen and phosphorous of the tested water were analyzed.The results show that the DO contents order of four kinds of aquatic plants was Eleocharis dulcis>Spianthes aristotelia>Iris pseudacorus>Pontederia cordata;the water turbidit... |
