摘　　要：为探究日间割胶对不同品种橡胶树产量、胶乳品质和生胶性能的影响,以广东茂名垦区团结农场6个橡胶树生产性栽培品种为试验材料,设定3个日间割胶时间处理,以传统的凌晨4:00割胶为对照,分析株次干胶产量、胶乳生理参数和生胶性能指标随割胶时间的变化趋势。结果表明:经双因素方差分析,产胶量受割胶时间和橡胶品种交互作用影响差异达显著水平,各生理参数对品种响应存在显著差异,对割胶时间响应不存在显著差异。干胶产量随日间割胶时间推移呈下降趋势,生理参数及生胶性能指标在各品种间变化趋势不尽相同。本研究设置的3个时间处理,最适合日间割胶的时间为早晨6:00;6个参试品种中,以胶乳体积、干胶产量和生理参数为评价指标,最适宜日间割胶的品种为热垦524和热垦525;以生胶常规指标及生胶性能为评价指标,最适宜日间割胶的品种为热研7-33-97和热垦501。综合考虑以提高劳动效率,增加胶工收入为目的,因此,本研究认为广东茂名垦区产胶高峰期可选用热垦524和热垦525于早晨6:00进行日间割胶生产。Three tapping time during the daytime of six rubber cultivars was set to explore the rubber yield,latex quality and raw rubber properties of different rubber varieties.The two-way analysis of variance showed that rubber produc-tion was significantly affected by the interaction between tapping time and rubber variety,and the response of each physiological parameter to the variety was significantly different,but there was no significant difference to the tapping time.The most suitable time for daytime rubber tapping is 6:00 am in the three daytime rubber tapping time treatment.Reken 524 and Reken 525 were the most suitable daytime rubber tapping variety judged by latex volume,dry rubber yield and physiological parameters.7-33-97 and Reken 501 were the most suitable daytime rubber tapping variety judged by common raw latex properties.Considering the purpose of improving labor efficiency and increasing the income of rubber workers,Reken 524 and Reken 525 could be used for daytime rubber tapping at 6:00 am during the peak rubber production period in Maoming Reclamation Area,Guangdong,China.
