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.
對雲南景洪農場六作業區橡膠樹RRIM600、PR107、GT1、雲研1號等品種實行刺激割膠新割製後的存在狀況進行調查,結果錶明:膠樹的病殘株率隨著割齡的增加而增高,在開割7年後現存株率、有效割株率及單位麵積有效割株數隨著樹齡的增加而降低;RRIM600在所有割齡段中,相對于其它參試品種錶現齣較彊的適應性,存株率、有效割株率及單位麵積有效割株數明顯較高、死皮明顯較輕.研究提齣應在更大範圍去深入調查,再認識RRIM600的優良性狀,作齣新的評價,閤理地應用于生產.

Investigation on several Hevea rubber cultivars (namely RRIM600, PR107, GT1 and Yunyan No.1, 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.
