摘　　要：对中国热带农业科学研究院试验场7队割制为割阴刀、1/8树围四天一刀(1/8s↑d/4)的橡胶树品种PR107胶树不同高度树干进行膨压测定。结果表明,割胶前橡胶树树干膨压分布不均匀,割胶后膨压下降较少。说明胶树茎干膨压一直维持在较高水平是气刺微割排胶时间较长的原因之一。Micro-cut is a new exploiting technique.There is a significant correlation between flow area and latex yield.Turgor pressure of trunk in the flow area on a rubber tree（Hevea brasiliensis） Clone PR107 with 1/8s↑d/4 tapping system was measured at NO.7 trial team,Chinese Academy of Tropical Agricultural Sciences.The result showed that there were differences among turgor pressure of different loci of trunk,and all of them decreased less after tapping.Turgor pressure of trunk keeping a comparative higher level is one of factors that flow of rubber trees with micro-cut and gaseous stimulation kept longer.
