In this paper, fixed point observations were made on the plantations of poplar varieties NL-95 and NL-895 and records were kept, and their growth rhythms and biomass were studied and analyzed. The results showed that the increment, stem form, resistance against longicorns and waterlogging resistance of poplar varieties NL-95 and NL-895 significantly surpassed those of the control poplar variety I-69 and could be used as fine poplar varieties to establish fast-growing and high-yield timber plantations in sand beach soil along Yangtze River.%本文通过对NL-95杨、NL-895杨两个杨树无性系营造的人工林进行多年定位观测记录,并对其生长规律和生物量进行研究分析.结果表明,NL-95杨、NL-895杨在生长量、干形、抗天牛等方面均明显超过了对照品种I-69杨,可做为沿江沙滩地营造速生丰产用材林的优良品种.
