摘　　要：以北京永定河沙地平原造林银杏为对象,设置不同的施肥处理,调查不同施肥水平下银杏生长量、叶片养分含量,探讨适合北京地区银杏复壮的合理施肥制度。结果表明:1)施肥可以有效地促进银杏的生长,改善银杏叶片以及土壤的养分状况;2)在2年的周期内,施用复合肥的效果要优于施用有机肥;3)在2年的周期内,按春、夏两季施肥,每株每次施用0.50kg复合肥可以作为北京地区银杏复壮的施肥标准;4)银杏的生长量、叶片养分与土壤水解性氮、有效磷、速效钾含量呈显著的正相关关系,而与土壤有机质、p H值的相关性较差。This study focuses on Ginkgo biloba L.in the Yongding river sandy plain afforestation,on the premise of setting different fertilizer treatments,the ginkgo growth and leaf nutrient were investiga-ted.The reasonable rejuvenation application of Ginkgo biloba L.was put forward in Beijing.The study showed that：1 ）Fertilization could effectively promote the growth of Ginkgo biloba,and improve Ginkgo leaf and soil nutrient status;2）The effect of compound fertilizer was superior to that of organic fertilize in 2 years;3）0.50 kg of compound fertilizer is applied per plant in spring and summer,which can be used as the fertilization standard in Beijing;4）The growth,leaf nutrient and soil hydrolytic nitrogen,a-vailable phosphorus,available potassium content have significantly positive correlation,and poor correla-tion with soil organic matter,and pH.
