Data analysis of production techniques from nine GT1 rubber clone blocks in 11 years has indicated that bark-tapping depth highly correlated with rubber tapping panel dryness （TPD） and tapping-stop rate at the level of 0.01 （1=-0.963; r=-0.906）, and moderately related to yield of dry rubber while bark consumption had less correlation with the yield, TPD tapping-stop rate and its occurrence rate.%通过对9个GTI品种橡胶树树位11年割胶技术资料的分析，结果表明割胶深度与死皮病发病率、停割率呈极显著的高度正相关（r=0．963：r=0．906），而与干胶产量呈极显著的中度相关；耗皮量与产量、死皮病停割率、发病率不存在相关关系。
