用定位研究的方法,在丹东不同区域建立生态因子观测场,测定不同土层厚度、pH值、土壤养分含量、空气温湿度、光照强度、降雨、蒸发量等各因子对银杏生长的影响,结果表明：在不同的温度条件下,银杏种子萌发和幼苗生长状况不同,经20 d后,种子发芽率恒温比变温高6.2个百分点,幼苗根系生长、苗高、地径恒温比变温分别提高36.7%和16%。经过遮阴处理,银杏幼苗生长好于对照区。生长在壤土和沙壤土上的银杏其生长表现优于生长在沙土和黏土上的,土壤含盐量以0.03%～0.043%,银杏生长良好。银杏对pH值适应范围很宽,在pH值4～8.5的土壤上均能生长。

Using method of the localization study,observation fields for ecological factors were set up in different regions in Dandong;effect of layer thickness,pH value of soil nutrient content,air temperature,humidity,light intensity,rainfall,evaporation and other factors on the growth of Ginkgo biloba were determined. Result shows that： under different temperature conditions,seed germination growth state of seedlings of Ginkgo biloba are different;after 20 d,constant temperature of seed germination rate are 6.2% higher than that of the variable temperature;root growth,constant temperature of seedling height ground diameter of seedlings increase by 36.7 % 16% than that of variable temperature respectively;after shading,seedling of Ginkgo biloba grow optimal than that in control area.Growth performance of Ginkgo biloba grow in loam sandy loam is optimal than that in sand clay;Ginkgo biloba grows well while soil salinity being 0.03%-0.043%;Ginkgo biloba which is adapted to a wide range of pH value can grow in the soils with pH value being 4-8.5.
