套袋对猕猴桃果实腐烂病的防病效果及果实品质的影响

Effect of Fruit Bagging on Fruit Rot and Quality of Kiwifruit

摘要: 2015 年和2016 年对浙江省江山市徐香猕猴桃果实进行套袋试验，研究不同套袋和去袋时间对猕猴桃果实腐烂病的防治效果及其对果实品质的影响。结果表明，2015 年5 月21 日套袋处理的猕猴桃发病率及病情指数低于其他处理及对照，差异显著，防治效果最高达到100%；6 月2 日以后套袋的处理发病率均在50%以上。8 月26日去袋防治效果最高，达70%；2016 年套袋处理的猕猴桃含糖量与各处理间差异均不显著；不同去袋时间的猕猴桃果实可溶性糖的含量均高于未套袋对照处理，且差异显著。

Abstract: Experiments were conducted from May 21 to August 7, 2015 on fruit bagging of Kiwifruit (Actinidia chinensis) in Jiangshan, Zhejiangprovince. The result demonstrated that bagging at May 21 had lower fruit rot occurrence than the other treatments, the control effect had 100%.Bagging after June 2 had more than 50% fruit rot occurrence. Bag removing at August 26 had the best control effect of fruit rot, about 70%.Experiment of bagging in 2016 demonstrated that soluble sugar content of fruit with different bagging time had no great difference among them, butdifferent removal time of bag had evident effect on soluble sugar content with that of the control.
