摘　　要：为探究不同杀菌剂与肥料联合施用对菠萝蜜裂皮病防效的影响,以定植12年的‘琼引1号’菠萝蜜树为试验材料,共设CK(正常管理)、FY1(47%春雷·王铜+325g/L苯甲·嘧菌酯+劲驼功能性水溶肥+海藻素+法琪酵母+抑线康生物有机肥)、FY2(2%春雷霉素+18.7%丙环·嘧菌酯+劲驼功能性水溶肥+海藻素+法琪酵母+抑线康生物有机肥)、Y3(死皮康颗粒剂+死皮康水剂+法琪酵母+抑线康生物有机肥)4个处理,每个处理分别设置5个不同浓度杀菌剂与肥料组合,重复6次。结果表明:与CK相比,FY1、FY2和Y3处理对菠萝蜜裂皮病均有明显的防效,其中,FY2的综合防效最佳,3个处理区15个不同浓度药剂与肥料组合的平均防效差异极显著;FY1-5的防效最高,为70.98%;FY2-5的防效最高,为82.60%;Y3-4的防效最高,为66.55%。防控菠萝蜜裂皮病的最佳药肥联用组合为FY2-5:2%春雷霉素1000倍液+18.7%丙环·嘧菌酯400倍液+劲驼功能性水溶肥200倍液+海藻素500倍液+法琪酵母500倍液+抑线康生物有机肥,建议在菠萝蜜生产中应用。To investigate the effects of different fungicides and fertilizers combined application on the control effect of jackfruit split skin disease,'Qiongyin No.1'jackfruits planted for 12 years were used as experimental material.Four treatments were employed CK(normal management),FY1(47%Chunlei·Wang Tong+325 g/L benzoyl·azoxystrobin+Jintuo functional water-soluble fertilizer+Seaweed element+Faqi yeast+Yixiankan bio-organic fertilizer),FY2(2%kasugamycin+18.7%Propionyl·azoxystrobin+Jintuo functional water-soluble fertilizer+Seaweed element+Faqi yeast+Yixiankan bio-organic fertilizer),and Y3(Sipikang granules+Sipikang aqueous solutions+Faqi yeast+Yixiankan bio-organic fertilizer).And five combinations of fungicides and fertilizers with different concentrations were set for each treatment and each was repeated for 6 times.The results showed that the treatments of FY1,FY2 and Y3 had obvious control effect on jackfruit split skin disease compared with CK,among which FY2 presented the best comprehensive control effect.Significant differences were also found in the average control effect of 15 combinations of concentrations of chemicals and fertilizers for three treatment areas.The three highest effects were found in the treatment of FY1-5,FY2-5 and Y3-4 with the respective concentration of 70.98%,82.60%and 66.55%.And the treatment of FY2-5 with the combination of 2%kasugamycin 1000 times solution+18.7%Propionyl·azoxystrobin 400 times solution+Jintuo functional water-soluble fertilizer 200 times solution+Seaweed element 500 times solution+Faqi yeast 500 times solution+Yixiankan bio-organic fertilizer was found the best way to prevent and control the split skin disease of jackfruit,which could be recommended to be applied in the production of jackfruit.
