摘　　要：以解淀粉芽孢杆菌HMQAU140045为研究对象,将其与苹果园常用9种杀菌剂进行了相容性试验,并分析了田间防治苹果斑点落叶病的效果。结果表明:在最高田间推荐剂量下多菌灵、醚菌酯、腐霉利均可促进解淀粉芽孢杆菌的生长;异菌脲、甲基硫菌灵、代森锰锌、多抗霉素轻微抑制其生长;苯醚甲环唑和戊唑醇强烈抑制其生长。田间药效试验结果表明,1×107 cfu·mL^(-1)解淀粉芽孢杆菌HMQAU140045菌悬液与70%代森锰锌WP500倍液、60%醚菌酯WDG 4 000倍液、80%多菌灵WP 800倍液、50%异菌脲WP 1 250倍液交替施用可有效控制苹果斑点落叶病的危害,秋梢停止抽生后防效达71.78%以上,对苹果树安全,提供了一条防治苹果斑点落叶病减量控害的有效手段。Compatibility of Bacillus amyloliquefaciens HMQAU140045 with nine kinds ot chemical fungicides commonly used in apple orchards and its field control effects against apple leaf spot were studied. The results indicated that carbendazim, kresoxim-methyl and procymidone could promote the growth of Bacillus amyloliquefaciens, and iprodione, thiophanate-methyl, mancozeb and polyoxin had slight inhibitory effects, while difenoconazole and tebuconazole showed strong inhibitory effects at their maximum recommended doses. The results of field trials showed a safe and effective method against apple Alternaria mali Roberts which could reduce the use of chemical fungicides by alternately using 107 cfu · mL-1 suspension of Bacillus amyloliquefaciens HMQAU140045 and other chemical fungicides such as mancozeb 70% WP 500 times, carbendazim 80% WP 800 times, kresoxim-methyl 60% WDG 4 000 times and iprodione 50% WP 1 250 times,and the final control effects were all above 71.78% in autumn tip stage.
