摘要： 本文以修武、辉县、济源、临颖、长葛杨树黄叶病害重发区林地的土壤为研究对象，研究了土壤营养因子中的铁、锰、铜、锌以及磷含量对杨树黄叶病害的影响。结果表明：土壤有效态铁相对含量低易发生杨树黄叶病病害，而土壤中有效态磷、铜、锌含量过高时，即使土壤有效铁含量较高，也易发生杨树黄叶病病害。

Abstract: The forest land area of soils from Xiuwu, Huixian, Jiyuan, Linying and Changge in where the yellow-leaf diseases of poplar outbreak in last year were collected. And, we studied on the effect of soil nutrient factors (i.e. Fe, Mn, Cu, Zn, P and so on) to yellow-leaf disease of poplar. The results indicated yellow-leaf disease of poplar would be severe occurrence if the content of available Fe was relative low in soil. But, it would be also severe occurrence even if the content of available Fe were high in some soil where the content of available P, Cu and Zn were relative high.
