在苹果花期施用不同药剂防治苹果霉心病试验结果表明,生物类药剂3%克茵康WP、10%宝丽安WP,1.5%多抗霉素WP能显著降低套纸袋富士苹果霉心病发病率,效果最好,病果率分别为3.7%、3.9%、4.9%,且对坐果率无任何影响。70%甲基托布津WP等化学类药剂能显薯影响苹果花序坐果率和花朵坐果率,使花序坐果事由97.3%下降到60.4%~72.0%,花朵坐果率由98.9%下降到64.7%~77.2%。所有试验药剂均能不同程度显著提高果实的畸形果率,提高幅度为3.9%~15.7%,但对果形指数无影响。 The results showed that the biocide 3% Ke Yinkang WP, 10% Polaroid WP and 1.5% doxorubicin WP can significantly reduce the incidence of mildew heart disease in the paper bag Fuji apple, The effect is the best, disease rate were 3.7%, 3.9%, 4.9%, and no effect on fruit set rate. 70% thiophanate-methyl, WP and other chemical agents can affect the apple inflorescence fruit setting rate and flower setting rate, the inflorescence fruit set from 97.3% to 60.4% ~ 72.0%, flower set fruit rate decreased from 98.9% to 64.7% ~ 77.2 %. All test agents can significantly improve the fruit of the deformity fruit rate to varying degrees, increased by 3.9% to 15.7%, but no effect on the fruit shape index.
