摘　　要：首次研究合理施肥对银杏园土壤肥力和酶活性的影响,结果表明合理施肥,改善了土壤理化性状,显著地提高了土壤肥力和土壤酶的活性;从而培育了银杏发达的根群,促进了树体的生长。增加了银杏鲜根重和百叶鲜重,减少了银杏黄化株率,提高了银杏挂果株率及种核的产量和品质。Effects of rational fertilization on soil fertility and enzyme activity in Ginkgo orchard were studied for the first time. The results show that rational fertilization can improve physicochemical properties of soil,significantly increase soil fertility and enzyme activity, thus cultivate well-developed roots and promote plant growth of Ginkgo. As a result,rational fertilization can increase fresh roots and leaves weight of Ginkgo, decrease yellow plant rate, enhance bearing plant rate, and improve the yield and quality of seeds.
