大花蕙兰在国际上享有盛名,因为它的花非常美丽。健壮的植株一茎可开花十几朵到三十朵。花硕大,直径可达10-13公分,花形规整,颜色鲜艳,有黄色、绿色、白色和粉红色,杂交品种更是异彩纷呈。花期特别长,整串花可维持50-80天之久。即使当作切花也不易凋谢。但是,由于大花蕙兰的原产地是高原山区,开花时期有比较冷凉的气候,所以多在温带地区栽培,要在亚热带地区栽培就难以开花。深圳农科中心从1988年起致力于大花蕙兰的规模栽培,并在控制花期方面取得成功。规模栽培一般选用生长势一致的同一批组培苗的幼苗,种到第三年可有一半以上的成株首次开花。开花的植株其假球茎已经相当健壮。越是粗大健壮的假球茎开花情况越好,所以在生产管理上要想方设法获得肥大的的假球茎,以期抽出更多更壮更长的花苔,开出数量多质量好的大串花朵。除了按常规的加强水肥管理之外,还要有意识地控制植株的营养生长,使养分集中供给将来要开花的假球茎,避免有限的养分作无谓的消耗,我们采用两种方法:一是控制花盆的规格,二是要做抹芽工作。
Cymbidium internationally renowned, because its flowers are very beautiful. A sturdy plant can blossom a dozen to thirty. Flowers huge, up to 10-13 cm in diameter, flower-shaped, bright colors, yellow, green, white and pink, hybrid species is more colorful. Flowering particularly long, the whole flower can be maintained for 50-80 days long. Even as cut flowers are not easy to withered. However, since Cymbidium origin is plateau mountainous area and has a relatively cool climate during flowering, it is more cultivated in temperate regions and harder to bloom in subtropical areas. Shenzhen Agricultural Center since 1988 committed to the large-scale cultivation Cymbidium, and flowering in the control of success. Large-scale cultivation generally use the same growth potential of the same group of seedlings of seedlings, seedlings in the third year may have more than half of the first flowering plant. Flowering plants have quite robust pseudobulbs. The more robust the fake bulbs flowering the better, so in the production management to find ways to get hypertrophy of the pseudobulbs, in order to extract more and longer and longer flowers, open a large number of good quality flowers. In addition to strengthening water and fertilizer management as usual, we also need to consciously control the vegetative growth of plants so that nutrient concentration can be supplied to the pseudobulbs that will bloom in the future, so as to avoid unnecessary consumption of limited nutrients. We use two methods: Basin specifications, the second is to do Mudai work.
