| 摘 要： | 应用二元二次饱和Ｄ－最优设计进行田间试验，探讨氮、镁对银杏叶黄酮含量的影响。结果表明，在镁缺乏的红土上种植银杏，在合理施用一定的氮肥基础上，增施适量的镁肥，对银杏叶黄酮含量的提高有良好效果。计算机寻优得到供试条件银杏叶黄酮含量最佳施肥方案为：Ｎ５６０ｇ／株，Ｍｇ１５０ｇ／株，目标黄酮含量为２．４８％。

| Abstract: | Using the dualityquadratic saturation Dthe optimization design,the field trail was couducted to study the effect of Nitrogen (N),Magnesium (Mg) two nutrient elements on flavonoides content of Ginkgo Bilobal leaves.The results showed that when Ginkgo biloba L.was planted in the soil of Mg deficiency,on the base of applying amount of N fertilizer,flavonoides content in leaves was increase well by applying proper Mg fertilizer.With the help of computer statistics,optiunum fertilizer scheme of N,Mg was N 560 g/plant,Mg 150 g/plant and objective flavonoides content 2 48%. |
