套袋对猕猴桃果实腐烂病的防治效果及果实品质的影响

Effect of Fruit Bagging on Fruit Rot and Quality of Kiwifruit

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。

Experiments were conducted from May21to August7,2015on fruit bagging of Kiwifruit(Actinidia chinensis)in Jiangshan,Zhejiang province.The result demonstrated that bagging at May21had lower fruit rot occurrence than the other treatments,the control effect had100%.Bagging after June2had more than50%fruit rot occurrence.Bag removing at August26had the best control effect of fruit rot,about70%.Experiment of bagging in2016demonstrated that soluble sugar content of fruit with different bagging time had no great difference among them,but different removal time of bag had evident effect on soluble sugar content with that of the control.
