不同年龄时期的柑桔,要求有相应的整形修剪技术:幼龄及初果期、要加速培养丰产树冠结构,以实现早期有较高产量;盛果初期,要控制树冠大小,推迟封行年限,以保持生长与结果的相对平衡,达到连年优质高产;树冠开始密闭后,要及时修剪疏伐,改善光照条件,合理利用光能,提高光合效率才能保持健壮树势,保证高产优质。澳大利亚Cary(1977)指出:“柑桔树冠大小的控制是持续高产的一个重要因素”。近期召开的国际柑桔会议,把《控制树冠大小》列为中心议题之一。可见,
Different age citrus, require the appropriate plastic pruning techniques: young and early fruiting period, to accelerate the cultivation of high yield crown structure in order to achieve a higher yield early; full fruit early, to control the size of the crown, delay the closure of the line In order to maintain the relative balance between growth and results, reaching year after year of high quality and high yield; canopy pruning began to prune the thinning in time to improve lighting conditions, the rational use of light energy and improve photosynthetic efficiency in order to maintain robust tree vigor to ensure high yield and quality. Australia Cary (1977) pointed out: “The control of citrus canopy size is an important factor in sustained high yield.” The recent International Citrus Conference, “control the size of the canopy” as one of the central issues. visible,
