摘　　要：为了研究郁金香花期延后的栽培方法,以10个郁金香品种为试验材料,分别研究不同生根发芽处理（箱栽露地生根＋2~5℃发芽＋0~2℃冷藏,露地生根、发芽＋0~2℃冷藏,延迟2个月箱栽露地生根、发芽＋0~2℃冷藏3种处理）、不同温度处理和光照处理对郁金香开花及生长发育的影响。结果表明,采用箱栽露地生根、发芽＋0~2℃冷藏处理,郁金香花的质量相似而成本低,是西安地区“五一”花期延后的较佳栽培办法;根系长出箱底刚露芽时是抑制芽延伸的最佳时期,0~2℃是抑制芽生长的最佳温度,移出冷库后郁金香在11~26℃生长速度比10~32℃快;每日从10：00到15：00在树阴下接受7380~14670 lx的光照比在太阳下接受60600~117300 lx的光照更利于郁金香株高、叶柄和花梗的伸长。Effects of different temperature and illumination on check cultivation about blooming period of tulip were studied with 10 cultivars by three different treatment （natural rooting ＋2-5 ℃sprout ＋ 0- 2 ℃ storage ; natural rooting, sprouting ＋ 0- 2 ℃ storage, plant 2 month later ; natural rooting, sprouting ＋ 0-2 ℃ storage） in order to study check cultivation of blooming period of tulip. The result showed that it was a better method to check cultivation of tulip in Xi＇an with natural rooting, sprouting ＋ 0-2 ℃ storage,because its cost was low when quality of flower was similar;the best opportunity for the sprouting of tulip was after rooting while sprouting just beginning at 0-2 ℃ and it had better growth at 11-26 ℃ than 10-32 ℃ ;there were longer plant height,petiole and stalk for tulip in 7 380-14 670 lx light intensity than 60 600-117 300 lx.
