摘要
对刺槐5个新品种材积生长量和形数分别进行了测算,得到材积生长量由大到小分别是多彩青山>壮美青山>紫艳青山>绿满青山>鲁刺10;f1.3与fa的变化趋势一致,但f1.3较fa偏大;通过分析胸径、树高与f1.3和fa的关系,得出结论:f1.3和fa随胸径的增大而减小的趋势较为明显,与树高大小的关系没有一致的规律性。
In this paper, the volume growth and shape number of five new varieties of Robinia pseudoacacia were measured separately.The amount of volumetric growth from large to small is Robinia pseudoacacia ‘Duocai Qingshan＇Robinia pseudoacacia‘Zhuangmei Qingshan＇Robinia pseudoacacia ‘Ziyan Qingshan＇Robinia pseudoacacia ‘Lvman Qingshan＇Robinia pseudoacacia‘Luci 10＇.The consistent trend of f1.3 and fa.But f1.3 is bigger than fa.By analyzing the relationship of breast diameter, tree height and f1.3 and fa.get conclusion：The trend of decreasing f1.3 and fawith increasing DBH is more obvious.There is no consistent regularity with the height of the tree.
