摘要
以北京杨作对照 ,研究了辽宁西部地区 15年生 10个杨树无性系的丰产林。通过对树高、胸径和材积方面的对比研究及个别年份的生长因子的方差分析、数量成熟年龄的分析 ,进行了优良无性系品种选择。研究表明 ,对于营造丰产林 ,87号杨 (P .×beijingensis) ,83号杨 (P .× popularis ) ,84号杨 (P .×deltoidesBartr.cv .‘Shanhaiguanensis’)较适合。
In this paper, the fifteen-year-old high-yield stands with ten domestic poplar clones were studied in west Liaoning Province. The diameter at breast height, height and volume in different clones were investigated, the variance were also calculated. The result showed that clone-83( P.×popularis ), clone-84( P.×deltoides Bartr.cv. ‘Shanhaiguanensis ’)and clone-87( P. × beijingensis )were suitable to be used as high-yield poplar clones. Meanwhile the quantitative maturity of different clones in high-yield forest was calculated. These provides a scientific basis for the rational selection of pulp forest clones and high-yield poplar clones in west Liaoning Province.
