金山绣线菊和金焰绣线菊在佳木斯市的引种适应性研究

Research on Introduction Adaptability of Spiraea×bumalda ′Gold mound′ and Spiraa×bumalda ′Gold Flame′ in Jiamusi City

对在佳木斯市新引种栽培的金山绣线菊和金焰绣线菊的物候期和抗寒性及生活力等进行观察,结果表明:金山绣线菊和金焰绣线菊在佳木斯地区的萌发期为4月下旬,展叶期为4月末,现蕾期为6月上旬,初花期为6月中下旬,抗寒性一般,等级为Ⅳ级,生活力等级为Ⅱ级,较好。初步认为作为地被植物可以在佳木斯市绿化中应用。

The observation of the phenophase（phenology）,cold hardiness and life force of Spiraea×Bumalda ′Gold mound′ and Spirae×Bumalda ′Gold Flame′ were introduced and cultivated in Jiamusi City.The results showed that for the Spiraea×bumalda ′Gold mound′ and Spiraa×bumalda′Gold Flame′ in Jiamusi City,their sprouting were late in April,leaf-expansion were at the end of April,budding were in early June,and early flowering stage were in mid and late June.They displayed ordinary freezing hardiness or freezing resistant abilities（Level IV）,and good life force（Level II）.So they could be used as ground cover plants in afforestation in Jiamusi City.
