早在1913年,就有人研究割胶对巴西橡胶树碳水化合物含量的影响。但各个学者的研究结果是矛盾的。最近关于割胶树和未割胶树的树皮碳水化合物含量的研究结果也是有矛盾的。重复使用刺激剂,产量效应就下降,这是橡胶业的一个严重问题,其原因尚未很好了解。树内能量贮备的消耗是造成这种产量效应下降的一个因素。为了探讨割 As early as 1913, someone studied the effect of tapping on the carbohydrate content of T. brasiliensis. However, the results of various scholars are contradictory. Recent findings on the bark carbohydrate content of gum cut trees and unspent gum trees are also contradictory. Repeated use of stimulants, the yield effect is declining, which is a serious problem in the rubber industry, the reason is not well understood. The depletion of energy reserves in the tree is a contributing factor to this decline in yield. In order to explore cut
