【摘要】 为丰富银川地区露地栽培花卉种类,引进了18种宿根花卉进行适应性研究。结果表明:引种品种中,除耧斗菜、风铃草、矾根未见开花外,三七景天、婆婆纳、天人菊、荷兰菊等15个品种均可以开花并正常生长;但飞燕草、羽扇豆和夏枯草播种出苗率较低和羽扇豆返青率较低;试验筛选出了花色艳丽、花序大、花期较长、景观效果好,对土、肥、水管理条件要求不高,可露地越冬,适宜于银川地区种植的品种12个,按其性状表现,依次为三七景天、福禄考、石竹、婆婆纳、天人菊、大花金鸡菊、千屈菜、美国薄荷、荷兰菊、月见草、钓钟柳、羽衣草。更多还原

【Abstract】 In order to enrich the types of open field growing flowers in Yinchuan area,18 kinds of perennial flowers were introduced for adaptability research.The results show that except Aquilegia vulgaris L.,Campanula medium L.and Heuchera micrantha,other 15 varieties of flowers such as Sedum aizoon L.,Veronica spicata L.Gaillardia pulchella Foug and Aster novaebelgii L.could all grow normally an bloom.But the rate of emergence of Consolida ajacis(L.)Schur.,Lupinus polyphyllus Lindl.and Prunella vulgaris L.as well as the greening rate of Lupinus polyphyllus Lindl.were relatively low.12 varieties with gorgeous color,larger inflorescence,longer flowering phase and good landscape effect were selected.Their requirements for the conditions of soil,fertilizer and water management are not high,they could survive winter in the open field and they are suitable for growing in Yinchuan area.According to their performance in characters they can be ranked as follows:Sedum aizoon L.,Phlox drummondii Hook,Dianthus chinensis L.,Veronica spicata L.,Gaillardia pulchella Foug,Coreopsis grandiflora Hogg.,Lythrum salicaria L.,Monarda didyma,Aster novibelgii L.,Oenothera biennis L.,Penstemon campanulatus,Alchemilla japonica Nakai et Hara.更多还原
