Abstract

Abstract: 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 investigated.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,available phosphorus,available potassium content have significantly positive correlation,and poor correlation with soil organic matter,and pH.

Key words: Ginkgo biloba L, rejuvenation technology, fertilization, correlation analysis
