保护地栽培条件下郁金香生长发育与种球复壮的研究

为研究保护地栽植对郁金香生长发育的影响,在江苏省连云港部分地区对郁金香进行了栽培及种球复壮试验,结果表明,保护地栽植均可使供试郁金香品种生育期提前,促进种球成球率,并改善栽培性状。其中,小拱棚栽植效果优于地膜覆盖,其各项指标差异程度因品种而异,早春采用小拱棚覆盖能明显提前郁金香的发芽和开花时间,并有效延长花后种球培养时间,显著提高成球率,使原本大部分丢弃的种球得以重复利用,实现了郁金香种球的国产化。

Studies on the Growth and Bulb Rejuvenation of Tulips in Protected Culture

The experiment which includes cultivation and bulb rejuvenation of tulips is conducted in the several area of Lianyungang in Jiangsu province. It aims at studying the effects of protected culture on the growth of tulips. The results indicated that protected culture may advance up growth time,promote the percentage of the bulbs rejuvenation, and improve cultivated character of the tested tulips varieties, therein the effects of low tunnel on cultivation and bulb rejuvenation of tulips are better than plastic mulching, the better effects is different in the different tested varieties, the culture in low tunnel in early spring obviously brought forward the date in bud and flower of tulips, prolonged efficiently cultivation time of the bulbs in postflorescence of tulips, and remarkably increased the percentage of the bulbs rejuvenation, thereby the reutilization of abandoned originally bulbs and the percentage of home-made parts in the bulbs breed of tulips may come ture,
