环境条件对重阳木生长的影响

对重阳木以通径分析方法分析其生长状况与环境条件的关系。结果表明:多行的重阳木与其生长状况呈较强的正相关关系,除直接作用外,根系半深埋,根系损害以及地面硬化等均可通过其对生长状况产生影响;根系正常与冠幅生长相关性较强,除直接作用外,多行,根系伤害以及地面硬化程度均可通过其对冠幅生长产生影响;单行的重阳木与树干生长关系密切,除直接作用外,根系深埋、根系伤害程度以及地面硬化程度均可通过其对树干生长产生影响;根系深埋推迟发芽时间,除直接作用外,单行以及地面硬化均可通过其对发芽时间产生影响。

Effect of Enviromnental Conditions on the Growth Status of Bischofia polycarpa

The relationships between growth status and environmental conditions of Bischofia polycarpa were analyzed by path analysis in Anhui agricultural university. The results showed： environmental con- dition that was multi-line was closely related with growth status, in addition to direct effect, half-buried root, root damage and hardened groundcould impact on the growth status through its; healthy root had a significant relevant with crown growth, in addition to direct effect, the multi-line, root damage, and hardened ground could also impact on the crown broadness through its; single-line was closely related with the growth of trunk, in addition to direct effect, deep-buried root system, root damage and hardened ground could also impact on the trunk growth through its;deep-buried root greater impact on the germi- nation time, in addition to direct effect, single-line and hardened ground could also impact on the germi- nation time through its.
