【摘要】 对生长在碱性地上的 14年生中山杉 30 2和落羽杉进行树干解析结果表明 ,中山杉 30 2的树高、胸径、材积生长量分别是落羽杉的 1 47,1 49和 3 31倍 ;材积的连年生长和平均生长曲线显示 ,中山杉 30 2能保持速生特性 ,而落羽杉的生长则相对较差。更多还原

【Abstract】 Stem analysis of the alkaline low land growing T.distichum and F 1 302,an interspecific hybrid between T.distichum and T.mucronatum,showed that the height,DBH and volume growth of F 1 302 are 147%,149% and 331% of the T.distichum The mean annual increment and current annual increment curve of volume indicate that F 1 302 could grow well under alkaline soil condition,while T distichum would be comparatively inhabited.更多还原
