摘要
为丰富陕北地区园林绿化的地被花卉品种,在参考前人研究成果的基础上,以榆林市引进的10种新型大丽花品种为材料,通过分株培育并跟踪观察记录其生长发育特性,并对其在陕北地区的生长发育规律进行观察和对比,以期为陕北地区园林的应用提供参考依据。结果表明,在花部形态方面,玫红增艳、雪青鹦鹉、粉妆楼、紫纹莲的观赏性较高;在花期性状方面,玫红增艳、红青莲、红旗漫卷的花期较长,可达90 d以上;在枝叶性状方面,除了出水芙蓉和紫纹莲外,其余品种叶色表现良好;在适应性方面,玫红增艳、红青莲、红旗漫卷、出水芙蓉、艳阳的成活率都达到了80%以上,玫红增艳、红旗漫卷、出水芙蓉、朝影、艳阳的萌蘖能力较强。研究表明,玫红增艳和红旗漫卷是比较优良的大丽花品种,可以大面积在陕北地区园林绿地中应用。
To enrich the land-covered flower varieties in northern Shaanxi,on the basis of reference to the results of previous research,the 10 new types of dahlias introduced in Yulin city were used as materials,according to cultivate and track the growth and the characteristics of growth and development including morphological characteristics,leaf traits,adaptability,etc..And the paper observed and contrasted its growth and development laws in northern Shaanxi province to provide reference for the application of gardens in northern Shaanxi.The results showed that in terms of flower shape,Meihongzenyan,Xueqingyinwu,Fenzhuanglou,Ziwenlian had high ornamental.In terms of flowering traits,Meihongzenyan,Hongqinglian,Hongqimanjuan had the longer flowering period,which was more than 90 d.In terms of foliage traits,in addition to Chushuifurong and Ziwenlian,the leaves of other varieties performed well.In terms of adaptability,the survival rate of Meihongzenyan,Hongqinglian,Hongqimanjuan,Chushuifurong and Yanyang reached more than 80%.Meihongzenyan,Hongqimanjuan,Chushuifurong,Zhaoyang and Yanyang had strong sprouting ability.On the whole,Meihongzenyan and Hongqimanjuan are better dahlias varieties which can be widely used in landscape greenbelt in northern Shaanxi.
