| 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。

| Abstract: | 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. |
