郁金香在拉萨温室引种的适应性研究

Study on the Adaptability of Tulip Introduced into Greenhouse in Lhasa

为郁金香在拉萨地区的栽培展示及丰富鲜花市场等工作提供参考依据,通过10个不同品种郁金香的温室栽培,对其物候期及植物学性状特征进行研究。“小黑人”植株最矮,具清香;“烛光”花期最长达25 d,叶片最宽且有条纹,花径最大,雌蕊最高;“阳光王子”花期较长,植株较矮;“红色印记”花期最短,但叶片最长,有叶缘短毛和叶片条纹;“粉色印记”开花最早,花期最长达25 d,茎粗最粗,叶面积最大,有叶缘短毛和叶片条纹,花冠、花葶最高;“橙色大帝”叶面积最小,内外轮花瓣最窄;“普瑞斯玛”具浓香,花葶最矮;“阿帕尔顿精华”具浓香,花药最短;“阿帕尔顿”具浓香,雌蕊最低。“玛雅”开花最晚且花期较长,植株最高,叶形指数最大。从荷兰引进的10个郁金香品种在拉萨温室均能够完成整个生活史,筛选出适宜拉萨温室栽培的优良品种8个,皆表现出各具特色的观赏价值。

To provide a reference for the cultivation display of tulips in the Lhasa region and the enrichment of the flower market,through greenhouse cultivation of 10 different varieties of tulips,the phenological period and botanical characteristics were studied.The plant of'Negrita'is the shortest and has a fragrance;the flowering period of'Candela'is up to 25 days,and the leaves are widest and striped,but the flower diameter is the largest,and the pistil is the highest;the flowering period of'Sunny Prince'is longer and the plant is shorter;the'Red Impression'has the shortest flowering period,but has the longest leaves with short hairs and leaf stripes;the'Pink Impression'has the earliest flowering,and the flowering period is up to 25 days,and has the thickest stem and the the largest leaf area,but the leaf has short hairs with leaf stripes,corolla and the highest scape;'Orange Empero'has the smallest leaf area and the narrowest inner and outer petals;'Purrisima'has a strong fragrance and the scape is the shortest;'Apeldoorn’s Elite'has a strong fragrance and the shortest anthers;'Apeldoorn'has a strong fragrance and the pistil is the lowest.'Maja'has the latest flowering and longer flowering period,the highest plant and the largest leaf shape index.Ten tulip varieties introduced from the Netherlands can complete the entire life history in the greenhouse in Lhasa,and 8 excellent varieties suitable for cultivation in the greenhouse in Lhasa were selected,all of which showed their unique ornamental value.
