摘　　要：对云南植胶区不同橡胶宜林地、海拔高度、坡向的橡胶树死皮病进行调查,结果表明,死皮病发病率与不同等级宜林地、不同坡向有关:植胶环境条件最好的宜林地死皮病发病率最高,而次等宜林地则发病率随之降低;西坡橡胶树死皮病发病率显著高于其它坡向发病率,从宏观角度一定程度地证实橡胶树营养状态与死皮病的关系。Results from investigation on rubber plantations indicated that there is a correlation of rubber tapping panel dryness with the natural stands conditions like different sites of rubber-planting, elevation and sloping direction. It＇s found that disease occurred most seriously in type Ⅰ region under good condition, type Ⅱ and type Ⅲ of rubber-planting regions in sequence. The occurrence of disease in plantations of west-hill was obviously higher than the other directions. In addition, it＇s proven that nutrition state of rubber tree is related to this disease to some degree.
