摘要：

本研究对云南省西双版纳勐捧农场的橡胶树死皮病停割树的症状进行调查。 结果表明：RRIM600 品系与GT1品系的橡胶树死皮停割树的比例均随割龄增加而增加；橡胶树停割树割线褐斑的比例，RRIM600品系随割龄增加而增加，而GT1品系则相反；RRIMM600品系与GT1品系死皮树的土壤全氮含量较健康树高。

Abstract:

A tapping panel dryness(TPD)syndrome survey was conducted in Mengpeng rubber farm. The result show that rate of tapping rest rubber tree for panel dryness increased with the increase of tapping year. The rate of brown spot in tapping panel of RRIM600 clone was increased with tapping year, but rate of brown sheet of GT1 clone was quite the contrary. The total nitrogen content of 0-20cm soil of healthy tree is lower than that of panel dryness tree both for RRIM600 and GT1 clone.
