耐热杜鹃花种质及其在暖热地区栽培研究进展

Review of Heat Resistance Rhododendron and Cultivation in Warmareas

本文对国内外低海拔炎热地区培育耐热杜鹃花的研究和报道进行了综述,海外筛选出微笑杜鹃、猴头杜鹃等23种杜鹃花用于培育耐热常绿杜鹃,采用大颗粒有机物或无机物为生长介质,高苗床或二重底的方式栽培杜鹃花,国内的研究结果同海外略有差异.此外,简要描述了部分杜鹃花的特性,以期为国内耐热杜鹃的培育和研究提供参考.

This paper summarized some researches and reports about heat resistant Rhododendron in oversea low altitude warm and hot climate areas from China and domestic both.23 species,for instance R.hyperythrum , R.simiarum ,were selected for breeding heat resistant Rhododendron by abroad man.They usually cultivated Rhododendron by coarse organic or mineral materials at elevating seedbeds or double-deck pots.Domestic conclusion was major identical but with minor differences.Meanwhile,part of heat resistant Rhododendron were described briefly,in order to providing a reference which refer in subsequent research.
