摘　　要：苹果无袋栽培模式下常见的果实病害如苦痘病、黑点病和红点病等严重影响商品果率和经济效益。试验以10年生琴富1号为材料,研究海洋生物功能肥不同施用量对其果实病害发生情况的影响,结果表明,随施肥量的增加防治效果更佳,均优于豆粕肥及常规商品有机肥的防治效果。对12年生的中早熟且抗病性不同的苹果品种琴富1号、斗南、名月和绯红验证该肥料的防效,结果表明,处理组的总病果率均显著低于对照组。The common fruit diseases such as bitter pox,black spot and red spot in apple baggless cultivation mode seriously affected the commercial fruit yield and economic benefits.In this experiment,10-year-old Qinfu No.1 was used as material to study the effects of different application rates of marine biological functional fertilizer on the occurrence of fruit diseases.The results showed that the control effect was better than that of soybean meal fertilizer and conventional commercial organic fertilizer with the increase of application rate.In addition,12-year-old apple varieties(Qinfu No.1,Dounan,Mingyue,Feihong)with different disease resistance were selected to verify the control effect of the fertilizer.The results showed that the total disease rate of the treatment group was significantly lower than that of the control group.
