通过对五家渠青格达湖旅游风景区内引种的50个郁金香品种进行观赏性状的观测，结果表明：所有品种在该地区露地条件下均能在4月中旬～5月中旬正常生长开花，整个花期持续时间约40 d，但各品种在花期和表现性状方面有所差异。文章还研究了温度对郁金香花期的影响，温度高于25℃时会导致郁金香提前凋谢。在整个花期内有阴雨天气也有高温天气，温度变化对郁金香花期会造成一定影响。通过调查与分析，表明在五家渠地区适宜栽培并能表现出较好的观赏性状的郁金香品种共25种。%The ornamental traits of 50 introduced varieties of tulip in Wujiaqu qinggeda Lake Scenic Area were observed. The results showed that all varieties under open field conditions in the region grew normally and blossomed from mid April to mid May with the flowering duration of about 40 days, but the florescence and performance traits depended on the variety. The effect of temperature on the flowering stage of the tulip was studied too. The tulip faded ahead of time when the temperature was higher than 25. There were rainy weather and high temperature weather in the whole flowing phase, and high temperature could affect the florescence in some degree. Through the investigation and analysis, 25 varieties of tulips suitable for Wujiaqu region with better ornamental traits were concluded.
