摘　　要：高山冷凉的气候条件适合郁金香生长，栽培不出现退化．将单球重小于１０ｇ的郁金香退化球及子球在海拔８８０ｍ处越夏贮藏及种植，收获后总球重有效增重在１倍以上，开花率提高，单球重大于１０ｇ的更新球比例增加明显．采取花后遮荫措施，平均叶枯收球期推迟１２天。It was found that the pleasantly cool weather of a mountainous region (Jinyun county, Zhejiang) was suitable both for the growth of tulip plants and the storage of bulbs, therefore no deterioration phenomenon existed. The deteriorated bulbs seemingly lacking the ability of flowering under the plain condition obtaied the flowering capability, and the harvested weight of total bulbs was over doubled when they were grown and oversummering stored at the attitude of 880 m elevation which their single bulb weight was less than 10 g. The ratio of regenerated bulbs whose single bulb weight was more than 10 g increased dramatically after harvest. The bulb rejuvenation was effective with the treatment of shading after blossom, and thd average date of leaves withering and harvesting was delayed about 12 days.
