| 摘 要： | 通过果园调查、室内化验分析，以及经田间小区试验、大田验证试验，查明了银杏幼树黄化的主要原因是土壤有效养分缺乏、pH值低（酸度大）、可能存在着铝毒危害等，并提出了相应的矫正措施；合理施用NPK、石灰、有机肥、B、Zn肥料，可以有效防治银杏幼树黄化。

| Abstract: | The cause inducing etiolation in Ginkgo bilola L. and measures to improve the etiolation were investigated in this study by investigating in orchard,chemical analysis,plot and field experiment. The result indicated that the etiolation in Ginkgo biloba L. was mainly due to the deficiency of efficient nutrients in soils. Low pH in the soils and corresponding aluminumtoxicity might also cause the etiolation. The etiolation was improved by applying of N,P,K,B,Zn,lime and orgnic manures. |
