| 摘 要： | 调查热研7-33-97、PR107、RRIM6003个品种橡胶树的不同割龄胶园单位面积存株数情况，并对存株类型进行归类。结果发现，存株类型可归类为正常割株、风害停割株、寒害停割株、割线干涸及产量挖潜株（阳线停割株、阴线割株、整树割线干涸停割株）、林下株、缺株等类型。其中热研7—33—97的1、5、10割龄的单位面积有效割株率分别为96％、85％、71％；PR107的1、12、14、16、20、24割龄的单位面积有效割株率分别为96％、67％、70％、75％、66％、46％；RRIM600的16、20割龄的单位面积有效割株率分别为64％和48％。文中还对对有效割株和其它存株类型进行了初步分析。

| Abstract: | Investigations wer e made on the unit area keeping plant types of three varieties Reyan 7-33-97,PR107 and RRIM600. The results showed that keeping plant types included normal tapping plants,stopped tapping plants as a result of wind injury,cold injury,tapping panel dryness,intensive tap-ping,as well as null plants and void plants. Of the three investigated varieties,the unit area effective tap-ping plant rate of Reyan 7-33-97 at the 1st,5th and 10th tapping year was 96%,85% and 71%,respectively. The unit ar... |
