九种水生观赏植物无性繁殖试验

Experiment on Vegetative Propagation of Nine Types of Aquatic Ornamental Plants

通过对宝鸡植物园的菖蒲、梭鱼草、芦苇等9种水生植物进行埋根段与单株繁殖试验,结果表明:菖蒲、梭鱼草、芦苇三种植物采用埋根段繁殖,方法简单,最高成活率可达100%;茭白、玉蝉花等六种植物采用单株带根、不带根繁殖,带根的成活率高于不带根的。

Cutting root reproduction and single plant reproduction were conducted with nine typs of aquatic ornamental plants like Acorus calamus, Pontederia cordata, Phragmites australis and so on. The result showed that Acorus calamus, Pontederia cordata and Phragmites australis by cutting root reproduction had survival rate reaching 100%;Zizania aquatic, Iris ensata and other kinds of plants were propagated by single plant reproduction with roots, and single plant reproduction without roots, out of which reproduction with roots generated higher survival rate.
