在中国西北黄土高原地区,水分是树木生长发育的主要限制因子.根系分布特征由于反映了树木对环境条件的利用程度而具有更加特殊的生态意义.本研究选择阳坡和阴坡不同立地上年龄一致的刺槐林调查了根系分布特征.根系垂直分布特征的调查结果表明,在所有立地上,根系生物量随着深度的增加而降低,其中细根的分布深度大于粗根的分布深度.方差分析结果表明:不同立地上不同径级根系的分布特征也有明显的差别,粗根是差异存在的主要原因,阴坡立地上的根系生物量,特别是细根生物量大于阳坡立地上的.对根系消弱系数的分析结果表明,阴坡立地上的根系消弱系数大于0 . 982 ,而阳坡立地上的根系消弱系数小于0 . 982 ,说明阴坡立地上刺槐根系的生物量在深层土壤中的分布相对量更大一些.其中细根的根系消弱系数大于粗根的,这种根系分布特征有利于根系对深层土壤水分养分的吸收利用,进而促进树木地上部分的生长发育.图3表3参15 | | 10. | Under 40cm , the contents are about 60mg / kg . 3 . under the different site types , the contents of soil organic matter , total n , available n , p , k have no obviously difference . but the height of the robinia pseudoacacia , the cap of the robiniapseudoacacia , the diameter of the robinia pseudoacacia above one meter of ground , the length of new branch have the similar disciplinarian : semi - shady > sunny > semi - sunny no matter what may , july , september
不同立地条件下土壤有机质、全氮、有效氮、速效磷和速效钾含量差异不显著，但刺槐的株高、冠幅、胸径、新枝却有明显的差异，无论是5月份、 7月份还是9月份、其株高、冠幅、胸径、新枝长度从大到小顺序均是：半阴坡半阳坡阳坡。 |
