摘　　要：城市樟树黄化病是一种常见病害,严重影响绿化效果。通过对城市樟树生理性黄化病发生特点的分析,探讨了城市樟树黄化病普遍发生的原因,即主要在于城市土壤的质量退化和碱性化;进而提出了城市樟树黄化病分区轮换土壤、施肥改土、树干注射与叶面喷肥相结合的综合防治技术,该技术应用于徐州市樟树黄化病防治中,取得了良好的效果。The Cinnamomum camphora yellowing is a common disease in city region and the value of the these tree landscapes have been decreased seriously. Analyses the characteristic and causal factors of the disease in city region was made in this paper. The key factors that disease occur were the soil texture because of too clay and harden; and the soil was polluted by the building garbage and sewage resulting in high soil PH value, in which Fe element was hardly absorbed by plant. The control measures that tree at soil improvement as key measure, and chemical as secondary one were suggested.
