摘要(Abstract)：

【目的】研究不同修剪方式对产量、果实色泽、品质和效益的影响,为柑橘简易修剪方法提供参考。【方法】连续2 a对重庆忠县2002年定植的‘哈姆林’甜橙进行精细修剪、开天窗回缩修剪、开门修剪和不修剪处理,试验前后测量各处理树体生长量和处理后产量,按国家标准GB8210-87方法测定果实理化性状,用日本美能达CR-10色差仪测定果实色泽,记录生产成本,用Excel进行数据处理,用SPSS Statistics17.0软件进行统计分析和差异显著性检验。【结果】结果表明,柑橘树修剪成本从大到小依次为精细修剪>开天窗回缩修剪>开门修剪>对照,病虫害防治成本从大到小依次为对照>开门修剪>开天窗回缩修剪>精细修剪,产量和品质从高到低依次为精细修剪>开天窗回缩修剪>开门修剪>对照。【结论】总体效益精细修剪>开天窗回缩修剪>开门修剪>对照。对于结果树而言,精细修剪适宜小面积的、生产精品果实的果园;开门修剪适宜干性不强、内部枝充实的柑橘树的果园;开天窗回缩修剪适宜大面积生产上推广应用;不修剪会严重影响产量和果实品质。
