摘　　要：为了给苹果栽培技术提供理论依据和制定科学的管理措施提供参考,对黔北地区苹果小叶病发生危害情况进行调查,并对该病进行肥料防治试验研究。结果表明,1苹果小叶病在黔北地区苹果产区每年的4~10月均有发生,一年中4~5月发病重,6~7月发病较轻,8~10月发病最轻;2施锌肥试验可知,施用硫酸锌肥135 g＋牛粪10 kg的效果最好,其次是硫酸锌肥165 g＋牛粪10 kg的效果,然后是硫酸锌肥105 g＋牛粪10 kg和硫酸锌肥150 g＋牛粪10 kg的效果。3防治苹果小叶病时应结合当地的环境条件、发病危害情况、发病条件和肥效试验等因素,采用以合理补充锌肥为主的综合配套防治技术。In order to provide theoretical basis for apple cultivation techniques and provide reference for scientific management measures, the apple little leaf hazard happens to suck region research and experimental study of fertilizer control of the disease were investigation and studied. The results showed that 1The apple little leaf in suck region of April to October every year, heavy incidence from April to May, lower incidence from June to July, the lightest incidence from August to October in a year; 2Effectiveness test showed that the use of zinc sulfate fertilizer 135 g ＋ cow dung 10 kg effect was best, the second was the effect of zinc sulfate fertilizer 165 g ＋ cow dung 10 kg, then zinc sulfate fertilizer was 105 g ＋ cow dung after 10 kg and zinc sulfate fertilizer 150 g ＋ cow dung kg effect.3Apple little leaf prevention and control should used comprehensive control technology which based on rational supplement of zinc fertilizer, combined with the local environmental conditions, disease hazard situation, applied conditions and test etc.
