摘　　要：在渭北黄土高原地区,以‘红富士'苹果为试材,以当地长放修剪为对照,探讨更新修剪对盛果末期苹果树体营养和果实品质、产量的影响。结果表明:更新修剪提高了叶片、枝条、果实、根系中的氮、磷、钾、钙含量,特别是枝条中的氮、磷、钾、钙含量得到极显著提高。更新修剪极显著提高了单果质量、产量及经济价值,显著提高了果形指数和有机酸含量,对果实着色面积、可溶性固形物、可溶性糖、维生素C、果实硬度无显著影响。表明渭北黄土高原应积极开展盛果末期苹果树的更新修剪。Compared with long-branch pruning in Weibei Plateau,Shaanxi Province,the effects of renewal pruning on'Red Fuji'apple tree's nutrition and fruit quality,yields in final full productive stage had been determined.The results showed that renewal pruning increased nitrogen,phosphorus,potassium,calcium contents in leaves,shoots,fruit and roots,and significantly increased nitrogen,phosphorus,potassium, calcium contents in shoots.Renewal pruning significantly increased fruit weight,yields and economic value, increased fruit shape index and organic acid contents,but had no effects on coloring area,soluble solids, total sugar,fruit vitamin C,fruit firmness.Weibei Plateau should actively extended renewal pruning in apple tree in final full productive stage.
