初步研究了由下往上的割面规划方法:当橡胶树茎干离地面100cm处的围径达到约50cm时,量取根颈处的围径,然后将该处围径等分为4个或8个割面（s/4、s/8）,各个割面的割胶年序均由根颈处开始依次向上排列。该割面规划法的低割面采用阴刀割胶:在上倾45°～50°、割线面外斜的割线上用拉刀由下往上割胶。采用该法割胶3a的结果表明,低割面s/4↑的产量、干含和生长量等与对照（高100cm处s/2）相当。

Preliminary study of the bottom-up cut plane planning method: When the stem diameter of rubber tree 100cm from the ground when the circumference reaches about 50cm, take the diameter of the neck at the neck, and then the circumference of the circumference is divided into four or 8 cut surfaces (s / 4, s / 8). The cut sequences of each cut surface are arranged in sequence from the root of the neck. The cut surface planning method of low cut surface with an overcast tapping knife: tilt 45 ° ~ 50 °, slanted line outside the slanted line with a broach from top to bottom tapping. The results of tapping 3a by this method showed that the yield, dry content and growth rate of low cut s / 4 ↑ were comparable with those of control (s / 2 at height of 100 cm).
