摘　　要：为揭示不同割龄橡胶树大丰95产胶量随采收期更替而变化的规律,以树位为单元,对其13个割龄在春、夏、秋、冬季4个采割期的干胶量进行测定分析。结果表明,不同割龄大丰95月株产干胶量和月公顷产干胶量月变化曲线除8 a割龄表现为单峰型外其余均表现为双峰型;夏季的6或7月份是大丰95产胶的高峰期,秋季11月份是另一个高峰期,在6或7和11月份的前2个月应加强肥水供应以提高树体养分的蓄积。各割龄大丰95的月株产干胶量与月公顷产干胶量均具有极显著的线性相关(P<0.01)。Dry rubber yields of Dafeng 95 grown in national Dafeng farm in spring,summer,autumn and winter,with 13 kinds of tapping ages,were determined and analysed taking task as the unit,to reveal change rule of the dry rubber yields in Dafeng 95 at different ages of tapping with harvest time alternating.The results showed that monthly variation of dry rubber productions per tree a month and dry rubber yields per hectare per month in Dafeng 95 of Hevea brasiliensis at 12 tapping ages still was double peak curve,except a single peak curve at 8 years age.It is June or July that the Dafeng 95 produces rubber in first peak period and second rubber producing peak period is November.Tree body requires an improved management of fertilizer and water inputs to increase its nutrient accumulation 2 months before the occurrence of the rubber producing peak.Dry rubber productions per tree a month and dry rubber yields per hectare per month at different ages of tapping showed a significantly linear correlation.
