摘要
1984-1997年,山西省实施中德林业技术合作"速生树种造林"项目期间,从德国引进欧洲山杨到山西,在全省不同区域栽植试验。23年后调查欧洲山杨的生长表现情况,通过生长量分析,以及综合赋分适应性评价,结果表明,欧洲山杨在不同试验区域的生长量明显大于对照或与对照差异不显著;欧洲山杨在山西基本适应,最适生长区为山西中南部的山区。
In 1984 to 1997,the China-Germany cooperation project "Afforestation with Fast-growing trees"was implemented in province Shanxi. During that time,Populus tremula was imported from Germany to Shanxi province,and the seedlings were planted in different area in whole province. After 23 years,the planted aspen trees were investigated. The growths,and integrated assessment points were analyzed. The results show: In different test areas,the growths of imported aspen trees are significantly bigger than CK or no significant differences with CK. The imported aspen is generally adaptable to Shanxi province. The best growing areas are the mountain areas in south central of Shanxi.
