摘　　要：为研究不同施肥水平及覆膜对喜马拉雅紫茉莉根部特征的影响,以便解决喜马拉雅紫茉莉的优质高产栽培技术,以喜马拉雅紫茉莉为试验材料,采用2因素有重复随机区组设计。研究结果表明,当栽培处理为A2B2,喜马拉雅紫茉莉的根鲜重、根长、根茎粗达最大,分别为39.3g/株,20.2cm/株,1.8cm/株。2种处理对喜马拉雅紫茉莉根部特征的影响差异均未达到显著水平,但是对根鲜重来说,覆膜方式对其影响相对较大;对根茎粗、根长来说,施肥水平对其影响相对较大。In order to study the effects of different fertilizer levels and coating on Mirabilis himalaica roots and to solve cultivation techniques of Mirabilis himalaica. The experimental material was Mirabilis himalaica, the experiment adopted repeated randomized block design. The results were presented as follows： when the deal with of cultivation was A2B2, the fresh weight of Mirabilis himalaica＇ roots was 39.3 g/strain, the root length was 20.2 cm/strain, the rhizome crude was 1.8 cm/strain. Two treatments did not reach a significant level on Mirabilis himalaica＇ roots, to the fresh weight and moisture content of root, coating types had a relatively large influence. For the rhizome crude and root length, the impact of fertilizer levels was larger.
