郁金香退化鳞茎在新疆昭苏地区复壮及再利用研究

为解决郁金香退化鳞茎及子鳞茎能否得到良好的复壮效果，以郁金香鳞茎种龄为依据，利用新疆昭苏地区适宜的地缘优势，采取不同的管护措施对退化鳞茎进行复壮。退化鳞茎经过1 年的复壮栽培，鳞茎种龄均由原来的2 级到达3 级，周径增长率高达8.73%~42.29%，并收获原数量2~3 倍的子鳞茎。研究表明昭苏的气候、土壤非常适宜郁金香的生长、复壮，是进行循环再利用以及产业化种植推广的理想区域。经过不同处理后，郁金香鳞茎都能够得到复壮，甚至达到商品球的周径要求，2 种处理差异不大，均可得到良好的复壮效果，复壮1~2年就可达到商品球的要求。

Rejuvenation and Recycling of Degraded Tulipa Gesneriana Bulbs in Zhaosu Area of Xinjiang

To examine the rejuvenation of degraded Tulip bulb, the authors rejuvenated the degraded bulbs of different ages under different management measures, utilizing the appropriate geographical advantage of Zhaosu area. After 1 year of cultivation and rejuvenation, the bulbs age was upgraded from class 2 to class 3, the growth rate was 8.73%-42.29%, and the number of bulblet was 2-3 times as much as before. The results showed that, the climate and soil of Zhaosu were very suitable for the growth and rejuvenation of Tulip, and it was an ideal area for recycle of the degraded Tulip bulbs and for regional industrial cultivation. After different treatments, the Tulip bulbs could be rejuvenated and even could be up to the requirement of the commodity ball circumference. The two treatments had little difference, both could obtain good rejuvenation effect, and 1 to 2 years rejuvenation could meet the requirements of commodity ball.
