死皮是橡胶生产中一个普遍而又严重的问题,因死皮而造成的经济损失是令人触目惊心的。据报道,1981年海南岛通什垦区3级以上累计死皮树比1970—1981年的十二年间累计风害全倒和断干2米以下的胶树仅少13000株,严重死皮率达14.4％,云南省西双版纳垦区1980年因死皮而停割的植株占开割胶树的8.5％。 Dead skin is a common and serious problem in rubber production, and the economic loss caused by dead skin is shocking. It has been reported that in 1981, the accumulated dead skin trees above grade 3 in Tonghua Reclamation Area of ​​Hainan Island had only 13,000 fewer gum trees than the total number of gum trees below 2 meters in the twelve years from 1970 to 1981, 14.4%. Plants cut dead due to dead skin in Xishuangbanna reclamation area in Yunnan Province accounted for 8.5% of open cut rubber trees in 1980.
