于苹果幼芽萌动期、开花前１～２天、坐果期、幼果期、果实迅速膨大期和成熟前期喷施１０００倍液苹果增产菌。经对幼果心室、萼筒分离培养表明：处理后果实心室和萼筒的有害微生物群落比对照少。成熟期和贮藏期调查表明：成熟期霉心病发病率可降低３．０％～１０．０％，病情指数降低６．７％～３３．２％；贮藏１个月后发病率降低１０．０％～２２．３％，病情指数降低１５．６％～４３．３％。
Buds in the apple budding period, 1 to 2 days before flowering, fruit set, young fruit stage, the rapid expansion of fruit and pre-mature spraying 1000 times the liquid to increase production of bacteria. After the young fruit ventricular, calyx tube separation culture showed that: after treatment fruit ventricular and calyx tube harmful microbial communities less than the control. The investigation of maturity and storage showed that the incidence of mildew could be decreased by 3.0% -10.0% and the disease index decreased by 6.7% -33.2% at mature stage, and decreased by 10.0 after 1 month of storage % ~ 22.3%, disease index decreased 15.6% ~ 43.3%.
