摘　　要：对云南景洪农场六作业区橡胶树RRIM600、PR107、GT1、云研1号等品种实行刺激割胶新割制后的存在状况进行调查,结果表明:胶树的病残株率随着割龄的增加而增高,在开割7年后现存株率、有效割株率及单位面积有效割株数随着树龄的增加而降低;RRIM600在所有割龄段中,相对于其它参试品种表现出较强的适应性,存株率、有效割株率及单位面积有效割株数明显较高、死皮明显较轻。研究提出应在更大范围去深入调查,再认识RRIM600的优良性状,作出新的评价,合理地应用于生产。Investigation on several Hevea rubber cultivars （namely RRIM600, PRI07, GT1 and Yunyan No.i, etc.） under treat- ment of new tapping system with stimulant has been conducted in No. 6 community of Jinghong State-farm. The results showed that the percentage of infected and stubble trees is getting rise while tree tapping age becomes old in all tested clones. Further- more, the elder the tapping tree is, the lower the percentage of living number, efficient tapping trees and efficient trees per unit will be in 7 years after tapping. Compared with other tested clones, RRIM600 performs well in adaptability, living number, effi- cient tapping trees,efficient trees per unit and low tapping panel dryness, at various tapping ages. It thus recommends to make a deeper investigation on clone RRIM600 for new assessment.
