| 摘 要： | 海南钻喙兰是具有较高发展潜力的新型热带花卉,花色美丽、芳香扑鼻,但缺乏切实可行的栽培管理技术,产业发展难以为继。本文分别以海南钻喙兰组培幼苗、成苗为研究对象,探讨不同基质对其生长、开花的影响,以期解决海南钻喙兰生产过程中各苗期栽培基质的选择问题。结果表明：(1)水苔是适宜的幼苗栽培基质,大棚、荫棚环境成活率为97.5 %,能较好的促进植株生长；松鳞处理成活率分别为100.0%与90.0%,对根长有较好的促进作用,为次优处理。(2)松树皮、木炭、火山岩混合基质利于成苗叶片、根系增长,是营养生长期适宜栽培基质,但不利于开花；1.0-2.0cm火山岩、松鳞处理开花率分别为90.0%、75.0%,对叶宽、茎高、根粗增长有一定的促进作用,适用于成苗促花栽培,其中松鳞较为经济环保,是优选促花基质。

Effects of Different Matrixes on the Growth and Development of Rhynchostylis gigantea |
| |
| Abstract: | The effects of different matrixes on the growth and flowering of the young and matured seedlings of tissue culture of Rhynchostylis gigantea are studied respectively, to solve the selection problem of the seedling cultivation matrix during the different production stage. The results were as follows: (1) sphagnum was a suitable cultivation matrix for young seedling. The survival rate of greenhouse and shade shed environment was 97.5%, which can promote plant growth better. The survival rate of pine squama treatment was 100.0% and 90.0%, respectively. It has a better promotion effect and is sub-optimal treatment. (2) The mixed matrix of pine bark, charcoal and volcanic rocks was beneficial to the growth of leaves and roots of the matured seedlings, which was a suitable cultivation matrix for the vegetative growth period but was not conducive to flowering. The flowering rate of 1.0-2.0 cm volcanic rock and pine squama was 90.0% and 75.0% respectively. It has a certain promotion effect on leaf width, stem height and root coarse growth, which was suitable for the flower cultivation of matured seedling. Among them, pine squama is more economical and environmentally friendly, and is preferred flower-promoting matrixes. |
