摘　　要：对死皮停割橡胶树和在割2-4级死皮树进行不同处理试验的结果表明,各处理对死皮停割树均无效果;在2-4级死皮树试验中,（NH4）2Mo4O13、Na2[B4O5（OH）4]、ZnSO4组合处理防治有效率最高,为66.7%~83.3%;康丰518和BR的处理有效率分别为50.0%、50.0%~66.7%和33.3%~66.7%,说明在割胶树割胶部位树皮补充微量元素营养和适宜的生物激素对控制死皮病的发生是有实际意义的。Chemical tests on tapping panel dryness（TPD） of Hevea rubber in various levels were carried out.The results indicated that all treatments have no effect on tapping-off trees,but chemicals combination of（NH4）2Mo4O13and Na2[B4O5（OH）4]and ZnSO4show the best control effect（ in the range of 66.7 percent to 83.3 percent） for affected trees in level 2 to 4.And the effective rates reach to 50.0%,50.0%-66.7% and 33.3%-66.7% respectively under the other three compound fertilizers treatments（Kangfeng 518 and Moinga oleifera solution,Kangfeng 515 solo,6-BA）.This showed that it is significant to control the occurrence of TPD while apply micro-element nutrition or appropriate bio-hormone to tapping bark of working rubber trees.
