摘　　要：[目的]研究6%抗坏血酸水剂对猕猴桃抗逆、抗病诱导效果。[方法]采用抗坏血酸水剂处理猕猴桃全生育期,通过调查猕猴桃开花整齐度,花果的受害率、病叶率、单果重等指标评价分析抗坏血酸水剂诱导效果。[结果]猕猴桃全生育期应用抗坏血酸水剂与常规处理区比较,花、叶受冻率降低3.5%,日灼病病果率降低7.3%,对叶斑病、褐斑病、溃疡病的防效提高12%左右,增产10%以上,提高了猕猴桃抗逆、抗病能力。[Aims] The paper aims to study the inducing stress resistance and disease resistance of ascorbic acid 6% AS to kiwifruit. [Methods] After treated with ascorbic acid 6% AS during the whole kiwifruit growth period, the induced effect of ascorbic acid 6% AS was evaluated and analyzed by investigating blossom uniformity, injury rate of flowers and fruits, the rates of diseased leaves, fruit weight and other indexes. [Results] Using ascorbic acid 6% AS during the whole growth period, compared with the normal treatment area, frostbite rate of flowers and leaves decreased by 3.5%, the sunburn disease rate of fi＇uit decreased by 7.3%, the control effect against leaf spot disease, brown spot disease and canker disease increased by 12% or so, respectively, production rate increased more than 10%, and stress resistance and disease resistance ability ofkiwifruit improved.
