本文叙述了修枝对RRJM600和GT_1树冠发育的影响.修枝处理有:胶园修枝、控制修枝加枝条诱导以及胶园低处修枝等四种.从分叉高度、树冠宽度、树冠厚度、树冠面积、树冠体积、树冠园度系数、树冠百分率、树冠展开度和树冠投影系数等参数讨论了树冠的发育.叙述了测定和获得这些参数的方法.修枝处理对分叉高度、树冠厚度、树冠面积、树冠体积及树冠百分率有影响,面对其它参数则影响较小.
In this paper, the effects of pruning on the crown development of RRJM600 and GT_1 were described.The pruning treatments were: plastic garden pruning, pruning and branch pruning, and low pruning of plastic garden etc.From the bifurcation height, canopy width, canopy Thickness, canopy area, canopy volume, canopy crown coefficient, canopy percentage, canopy expansion and canopy projection coefficient were discussed.The methods of measuring and obtaining these parameters were described.The pruning treatments were applied to the furcation height, Thickness, canopy area, canopy volume and canopy percentage had an impact, in the face of other parameters, less affected.
