摘    要
   本文通過應用不同的冷藏時間、水培界限、光照強度以及消毒與否等處理方法，初步探索冷藏處理對廣西莪術種球開花的影響。結果表明，冷處理時間越長，種植后植株生長時間越短，開花越早。因此通過延長廣西莪術種球的冷處理時間，可以縮短溫室生長時間，根據具體需要達到調節花期。此外,較高溫度下培養的植株的始花期、盛花期、凋花期均比處于常溫短，而且開花率、開花質量均較為理想。可見溫度在廣西莪術的花期調控中具有決定性的作用。未發現光照強度對廣西莪術的開花率有影響。
關鍵詞:廣西莪術 冷藏 開花率 始花期 凋萎期

Effects of Rhizome Cold-Storage on Flowering of
Curcuma kwangsiensis

Abstract:  Flowering of Curcuma kwangsiensis rhizome were studied when hey were treated by cool –storing, culturing in Water and others. The results showed that: Curcuma kwangsiensis plant growed faster and blossomed more early with longer cool –storing time,so flowering period of Curcuma kwangsiensi could be regulated by controlling cool–storing time of Curcuma kwangsiensis rhizome.The different flowering period of the treated rhizome that were cultured at higher Temperature were shorter than that of the control ,and it had higher flower percentage and flowering quality Compared with the control . temperature  was Obviously the key to flowering period regulation of Curcuma kwangsiensis. Light intensity could not affect flowering rate of Curcuma kwangsiensis independently.
key words: Curcuma kwangsiensis ; Refrigeration; flower percentage ; Flowering period ;Wilting period
