摘　　要：本文作者试图利用地被菊这一优良材料进行林下栽培,通过不同遮荫处理,对地被菊‘紫勋章’花期观赏品质进行了研究。结果表明:经隶属函数分析,不同光照强度下地被菊‘紫勋章’的开花能力依次为全光80%>全光60%>全光100%>全光40%>全光20%>全光10%。地被菊适合生长于全光40%以上范围的环境中。花青素含量、总黄酮含量与光照强度均呈显著正相关,相关系数分别为0.842、0.795。In order to cuttivate and promote the ground-cover chrysanthemum（Dendranthema grandiflorum Kitamura）under- trees,it was the effects of different light intensities on blooming traits of ＇ Zi Xunzhang＇ were investigated in this study. The re- sults showed that the flowering ability depended on the light intensity, followed by 80%, 60%, 100%, 40%, 20% and 10% of light intensities. It could be concluded that the plants growing above 40% of flight intensity could get better blooming traits. The contents of anthocyanin and total flavonoids were positive correlated with the light intensity and the correlation coefficiency were 0. 842 and 0. 795, respectively. In short, above 40% of light intensity was an important factor on blooming traits of grow- ing ground-cover chrysanthemun, such as anthocyanin content.
