本文简单地讨论了橡胶树分叉处的受力情祝,并分析了分叉处受力的实验结果,求得估算各类枝条分叉处能承受最大弯矩的经验公式,还查明影响分叉处弯矩的主要因子是被拉技条围粗。分析结果表明,对分叉处的锯伤可削弱其承受弯矩(抗裂断)的能力,并应用经验公式可求得不同锯伤处理所削弱其抗裂断能力的程度;分叉处锯伤处理将可能是多级多分枝树型的胶树预伤抗风的有效途径。 In this paper, we briefly discuss the mechanical behavior of rubber tree bifurcation and analyze the experimental results of the bifurcation forces, and obtain the empirical formula for estimating the maximum bending moment of bifurcated branches. The main factor for the bending moment at the fork is the thickening of the drawing technique. The results show that the sawing on the bifurcation can weaken the ability of the bracing to bear the bending moment (cracking resistance), and the empirical formula can be used to find out the degree of anti-cracking ability of the saw billet. Wound treatment may be an effective way to resist the wind damage of the multi-stage multi-branch tree gum tree.
