摘要
为了提高银杏的经济功能,开展了银杏叶产量和质量的影响因素调查。结果表明:银杏栽植密度为40cm×60cm时,产叶量最大;在土壤含水量62%时,其黄酮、内酯含量最高;截干能促进萌条增多,扩大冠幅面积,使叶产量和黄酮、内酯含量明显提高;银杏在生长季内,叶的黄酮、内酯含量随季节变化呈升高趋势,到9月时效果最好。
In order to improve the economic function of Ginkgo biloba,the influencing factors on the yield and quality of Ginkgo biloba were investigated.Result shows that the planting density of Ginkgo bilobais 40 × 60㎝ and the leaf yield is the largest.The content of flavonoids and lactones is the highest when the soil water content is 62%.Truncatus can promote the increase of sprout,enlarge the area of crown,make the leaf yield and the content of flavone and lactone increase obviously.During the growing season,the content of flavone and lactone in leaves increased with seasons,optimal effect can be obtained in September.
