摘　　要：扼要评述了国内外对橡胶树死皮病病因的研究;在前人研究和对云南橡胶树死皮病发生发展大量田间资料研究的基础上,结合作物栽培学、营养学和森林衰退病的基本理论,提出橡胶树死皮病是橡胶树群体在一定的割胶生产条件下营养失衡,导致整株或局部树皮组织衰退,局部或全部失去排胶功能的一种生理病害,而过度排胶,养分不能适时足量供给,是死皮病不同程度发生、发展的主要病因。Relevant studies on Tapping Panel Dryness(TPD) of Hevea rubber at home and abroad are reviewed. Based on the previous studies and data of field investigation in Yunnan Province, combined with the basic theory of crop cultivation, nutriology and forest decline, it points out that Hevea TPD is a kind of physiological disease which rubber trees show nutritional imbalance under a certain production condition, resulting in the whole plant or partial bark degeneration and lose their discharging function, and over-flowing latex from Hevea rubber population and insufficient nutrition supply could be the main cause resulted in TPD disease, according to the author.
