摘要: 为探索施氮对叶用银杏叶片产量及叶黄酮含量的影响, 按0 , 1.5 , 3.0 , 4.5 和6.0 g株-1等5 个水平进行施氮试验, 结果表明:不同施氮水平对银杏叶产量及其构成因子有显著影响。施氮量在3.0 g株-1 以下, 氮的增施对叶产量、单叶面积、单株叶面积及单叶质量等均有良好的促进作用, 以3.0 g株-1为最佳, 超过3.0 g株-1时, 苗木会受到毒害, 以上各指标均下降;施氮对银杏叶片黄酮含量和黄酮总量均有显著的影响;5 种施氮处理中, 以1.5 g株-1的叶片黄酮含量和黄酮总量最大。1.5 g株-1可作为2 年生银杏叶用园的推荐施用量, 可望获得单位面积上较高的黄酮产量。表5 参10

Abstract: In order to study the effects of nitrogen application on leaf output and flavone concentration in leaves of ginkgo seedlings , two-year-old ginkgo seedlings were transplanted and grew in pot culture at five levels of nitrogen(N)supply :0 , 1.5 , 3.0 , 4.5 and 6.0 gseedling-1 .The results of the trial were showed as follows :① Different levels of nitrogen supply had remarkable effects on the leaf output and its component items .With increasing levels of N supply from 0 to 3.0 gseedling-1 there were greater leaf output , single-leaf area , leaf area per seedling and single-leaf weight , while with increasing levels of N from 3.0 to 6.0 gseedling-1 all of the items decreased, which indicated that seedlings were injured by excessive nitrogen supplies .②Different levels of nitrogen application marked effects both on flavone content in leaf and flavone yield in per seedling of ginkgo .Among five treatment of nitrogen application , the treatment 1.5 gseedling-1 had greatest flavone content in leaf and flavone yield in per seedling .③1.5 gseedling-1 should be recommended as the proper amount of nitrogen application for two-year-old leaf-producing plantation of ginkgo , by which greater flavone yield in per unit area could be expected .
