【摘要】 对山西省3个杨树栽培区域(太原晋中、长治晋城、临汾运城)的主要杨树栽培品种(毛白杨、107杨、108杨)进行树干解析,调查不同品种在不同区域胸径、树高和材积的实际生长量,对比分析同一品种在不同地区的生长状况。结果表明:毛白杨的胸径、树高和材积生长量依次为临汾运城地区>长治晋城地区>太原晋中地区;107杨、108杨的胸径、树高和材积生长量依次为临汾运城地区>长治晋城地区;临汾运城地区107杨、108杨各项生长量大于毛白杨,在该地区选择107杨、108杨作为速生品种较好;长治晋城地区毛白杨的各项生长量大于107杨、108杨,在该地区选择毛白杨栽植为好。更多还原

【Abstract】 The growth of the same poplar variety was analyzed comparatively by stem analysis of different variety in different regions,DBH,tree height and actual volume growth with poplar cultivars(Poplar,107 Yang,108 Yang) were investigated in three poplar cultivation regions in Shanxi(Taiyuan and Jinzhong,Changzhi and Jincheng,Yuncheng and Linfen).The results showed that the growth order of DBH,tree height and volume growth of poplar was Yuncheng and Linfen,Changzhi and Jinzhong,Taiyuan and Jinzhong;the growth order of DBH,tree height and volume of 107 Yang,108 Yang was Yuncheng and Linfen,Changzhi and Jinzhong.The growths of 107 Yang,108 Yang were more than that of poplar in Linfen and Yuncheng,so 107 Yang,108 Yang were suitable fast-growing varieties in the region.The growths of poplar were more than those of 107 Yang,108 Yang in Changzhi and Jincheng,so poplar was selected firstly as fast-growing varieties in the region.更多还原
