摘要(Abstract)：

研究设施栽培桃果实采后适宜修剪量,为设施栽培桃不同品种采后修剪提供指导。以曙光与早红艳4 a生成龄树为试材,连续6 a在果实采后对1 a生枝组进行适宜修剪量试验。以不修剪为对照,按剪下叶量占植株总叶量比例进行轻度(20%~30%)、中度(40%~50%)和重度修剪(70%~80%)及全剪处理,分析不同修剪量对树冠的光截获能力、1 a生枝组叶片的净光合速率和1 a生枝组的年生长量以及植株总产量和果实品质的影响。结果表明,对曙光进行中度修剪处理,后期结果枝组能更快形成,短果枝比例降低,更有利于提高单株负载量和果实品质。对早红艳进行轻度修剪处理,枝条总数增加,短果枝比例降低,植株负载量及果实品质明显优于对照,该品种更适于轻度修剪。
