对中国海南、云南和广东三大植胶区不同品种、不同割龄橡胶树死皮发生现状及田间分布情况进行调查。结果表明：全国橡胶树死皮率高达24.71%，停割率为14.55%；三省国营农场死皮率和三级以上死皮率大小顺序依次均为：云南＜海南＜广东，死皮率分别为20.77%、28.08%和30.90%；死皮率随割龄的增加而增加，不同品种死皮率与停割率大小顺序依次为：热研7-33-97＜PR107＜GT1＜RRIM600＜南华1号。此外，死皮树存在连株分布的现象，且随着割龄的增加，连株分布的现象越明显。

In order to study the occurring and field distribution of tapping panel dryness (TPD) in Hevea brasiliensis in the main planting areas of China, an investigation was carried out on the TPD occurring and field distribution of rubber trees in different clones and tapping ages in Hainan,Yunnan and Guangdong, respectively. The results showed the rate of TPD reached up to 24.71% and the rate of stopage was 14.55% in China. The rates of TPD and TPD over the third class of rubber trees in state farms as follows:Yunnan<Hainan<Guangdong, and the rates of TPD corresponded to 20.77% , 28.08% and 30.9% , respectively. The TPD rates of rubber trees increased with growth of the tapping ages. The orders of the rates TPD and stop-tapping from different clones from low to high were all Reyan7-33-97<PR107<GT1<RRIM600<Nanhua 1. In addition, the spread of the TPD trees from tree to tree along the planting line was found, and with the increasing of tree age, the spread pattern was more obvious.
