摘　　要：在瓦房店市玉米主产区炮台镇、泡崖乡进行玉米田土壤肥力变化试验。试验表明:研究区土壤有机质含量适宜,土壤磷含量丰富,土壤速效钾略有降低,未表现出钾素的缺乏。通过调查当地施肥方式,分析出玉米田土壤肥力变化的主要原因在于只重视化肥施用,而忽视有机肥的施用和有机物料的还田。针对玉米施肥方式存在的问题,提出具体的改进建议。This paper, taking Wafangdian City as the study subject, through a questionnaire survey and collecting information, examines the developing trend of farmland soil fertilization. The experiment shows that the organic content in the researched soil is proper, and the phosphorus content is rich while there is a slight decrease in the content of available potassium and there is no indication of lack of potassium. This article analyses the problems in the way of fertilization, and proposes major initiatives to improve corn fertilization.
