海南6种切叶花卉植物橡胶林下套种的适应性研究

摘要

The adaptability of six leaf cutting flower plants with shade-tolerance interplanted in Hainan rubber for-est were studied, and they were Chrysalidocarpus lutescens, Dracaena fragrans, Dracaena sanderiana, Rhapis ex-celsa, Monstera deliciosa and Cordyline fruticosa.The research indicators include phenological period of leaves, appearance of the overall plant, height, leaf color and insect pests injury degree.The results showed that the a-daptability order was Dracaena fragrans >Cordyline fruticosa >Chrysalidocarpus lutescens >Monstera deliciosa >Rhapis excelsa>Dracaena sanderiana.Dracaena fragrans showed the best adaptability with the highest score, and it was the most suitable plant which could be interplanted in Hainan rubber forest.%通过对散尾葵、金心巴西铁、金边富贵竹、莲花竹、龟背竹、朱蕉等6种耐荫型切叶花卉植物在橡胶林下进行套种（扦插）试验，观测这些植物的叶片生长物候期、植株整体感、株高、叶片色泽和病虫害危害程度，分析这6种切叶花卉植物在橡胶林下的生长适应性。结果表明，适应性强弱排序为金心巴西铁＞朱蕉＞散尾葵＞龟背竹＞莲花竹＞金边富贵竹，其中金心巴西铁在橡胶林下生长综合表现最好，评价得分最高，为17.22，适合在海南橡胶林下推广种植。
