摘　　要：施肥是杨树速生丰产林建设的关键技术。在阐述杨树养分特性和养分诊断技术的基础上,分别从施肥效应及其影响因素和施肥技术方面综述了20世纪50年代以来的国内外杨树施肥研究,并提出3点建议:形成适于不同区域、不同土壤类型和不同品种无性系的施肥技术体系;注重和加强淋溶、水肥耦合等施肥机理的研究;借鉴农业先进施肥技术,摸清杨树与土壤的养分供求关系,实现林业精准施肥。Fertilization is one of the most important techniques on the cultivation of fast - growing and high - yield poplar plantation. In this paper, based on elaborating the poplar＇s nutrient characteristics and nutrition diagnosis techniques, the poplar＇s fertilization at home and abroad since the 1950s was reviewed in 3 aspects, i.e. fertilization effect, affecting factors and fertilization techniques （fertilizer types, fertilization season and numbers, fertilization amount and fertilizer rotio, etc. ）. Moreover, three suggestions were put forward for the research ： 1 ） establishing a fertilization technique system of poplar suitable for different regions, different soil types and different varieties; 2） paying attention to mechanism research on leaching and water -fertilizer coupling; and 3 ） realizing precision fertilization through utilizing the advanced agricultural fertilization techniques and mastering the nutrient supply and demand between poplar and soil.
