| 摘 要： | 为生态竹林建设的管理管护提供科学依据,采用吸附甲烯蓝法对海子坪天然毛竹根系吸收能力进行测定。结果表明:天然毛竹无性系种群分株年龄与根系的吸收能力存在密切关系,壮龄天然毛竹无性系种群根系吸收能力最强,幼龄最弱;天然毛竹无性系种群根系具有密度大、体积小的特点。 |
| 关 键 词： | 毛竹无性系种群 吸收能力 根系 |

| Abstract: | The root absorptive capacity of Haiziping natural P.pubescens was detected by the method of absorbing methylidynel blue to provide a scientific basis for management and protection of ecological P.pubescens forest construction.The results showed that the ramet age of natural P.pubescens clonal population has close relationship with root absorptive ability;the two or three-year-old ones had the strongest absorptive ability,while the one-year-old ones had the lowest;its root was of high density and small volume. |
| Keywords: | Phyllostachys pubescens clonal population absorption ability roots |
