摘要
通过对海南黄花美冠兰[Eulophiaflava(Lindley)Hookerf.]原生境状况的调查和引种栽培,研究其生长发育规律,并扼要讨论了黄花美冠兰的开发前景、栽培、繁殖和规模化生产中尚待解决的问题。结果表明:黄花美冠兰不耐低温,是典型的喜温花卉;发芽适宜土温26℃左右;开花适温27～33℃;营养生长适温26～31℃,气温低于15℃时,生长停滞,进入休眠;种球贮藏适温20℃左右。黄花美冠兰的童期较长,生长前期不耐强光,成花受芽发育状况、假鳞茎养分贮藏状况和环境条件等多方面的影响,开花需要一定的光照强度。
A survey was made of the primary habitats of Eulophiaflava （Lindley） Hooker f. （Orchidaceae）. E. flava was introduced for trial planting to observe the growth and development. The results revealed that E. flava was a typical thermophilic flower. The suitable temperature for germination （soil temperature）, flowering, vegetative growth, and storage of ball was 26℃, 27～33℃, 26～31℃, and about 20℃ respectively. E. flava was intolerant to intensive light at the early stage of growth, and its flower development was affected by some factors like developmental conditions of buds, nutritional storage in pseudobulbs and environmental conditions. A given intensity of light was needed for flowering.
