| 摘 要： | 通过对橡胶树割胶树位调查,低于20割龄胶树实施新割制,一般表现干胶产量增产和年度间产量变化平稳,累计死皮病率低,而高于20割龄胶树实行新割制、老龄割制和强割制,虽然提高刺激剂使用浓度,仍不能表现干胶增产,同时4～5级死皮率明显增高;品系GT1表现比RRIM更耐刺激,增产幅度大,死皮率更低。

| Abstract: | The investigation of tapping rubber trees was carried out.The results showed that the yield of dry rubber increased in a year with low ratio of DTP without any change if new tapping system was put into effect to rubber trees below 20 years old.And although more concentration of stimulating agent was necessary to trees obove 2under different systems(new tapping system,old tree tapping system and intensive tapping system),there is no significant change for dry rubber.Meanwhile,DTP(grade 4-5) occurred greatly.Clone CT1 showes better than clone RRIM in stimulating,yield increased significantly with low ratio of DTP.0,the yield would increase greatly with lower ratio of DTP while new tapping system for old trees and intensive tapping system were implemented. |
