摘　　要：以常规的乙烯利刺激割胶(S/2d4)为对照,比较分析了乙烯气刺条件下不同割线长度(S/8Ud4、S/4Ud4、S/2Ud4、3S/4Ud4)割胶对干胶产量以及与产排胶相关的各项生理指标的影响。结果表明,气刺割胶可获得比常规的乙烯利刺激割胶更好的产量效应;气刺条件下采用3S/4Ud4割制初期产量增幅明显,但第2年时产胶潜力下降,对于高产稳产胶树采用S/8Ud4割制不仅可获得持续高产且生理状况良好。The rubber yield and some physiological parameters between conventional tapping system （S/2d4） and ethylene gas stimulation with different tapping length （S/BUd4, S/4Ud4, S/2Ud4, 3S/4Ud4） of Hevea Brasiliensis were comparatively analyzed in the study. The results showed that more dry rubber yield was harvested in the rubber tree stimulated with ethylene gas than conventional ethylene stimulation. The tapping system 3S/4Ud4 had higher yield at the beginning of the trial, but the yield potential was decreased significantly in the second year. The S/8Ud4 system showed good yield and phvsiolozical parameters for high and stable yields of rubber tree.
