| 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7 380～14 670 lx的光照比在太阳下接受60 600～117 300 lx的光照更利于郁金香株高、叶柄和花梗的伸长。 |

| Abstract: |
| 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. |
