我省从六十年代初期,开始引进国内外杨树新品系,到目前已有六百余种(包括纯种,变种,杂种、无性系),这样繁多的杨树品系,要做到适地适树,除了进行栽培和立地条件的分析研究外,建立杨树品种比较林也是十分重要的。我省已在不同地点,不同立地条件下建立了一些杨树品种比较林,本文是对河北省林科所试验场和漳河林管局漳河林场两处杨树品种比较林生长情况,进行调查研究。 Since the early 1960s, our province has introduced new poplar lines at home and abroad. Up to now, there are over 600 poplar varieties (including purebreds, varieties, hybrids and clones), so many varieties of poplar trees should be properly adapted to trees , In addition to the analysis of cultivation and site conditions, the establishment of comparison of poplar species is also very important. The province has established some poplar species comparison forests at different sites and different site conditions. This paper compares the growth of two poplar species in Linhe Institute of Hebei Province and Zhanghe Forestry Bureau of Zhanghe Forestry Bureau, Research.
