| 摘 要： | 试验采用了正交区组二次回归设计 ,以氮、磷、钾配方施肥为研究对象 ,系统地进行了湖北麦冬产量的分析 ,建立的施肥与产量之间的回归模型表明 :氮肥、钾肥对产量有显著的影响 ,磷肥则不明显。氮肥与磷肥的互作效应对产量的影响呈互补关系 ,在较低磷肥时随施氮肥的增加而产量增加 ,反之则下降。高氮、高钾、低磷配方施用能达最高产量点 ,施用N 4 5 5 7～ 4 95 4kg/hm2 、P2 O52 5 9 5～ 312 2kg/hm2 、K2 O 6 95 1～ 75 7 3kg/hm2 ,产量为 75 0 0kg/hm2 以上的概率为 99%。

| Abstract: | This experiment adopt three factors quadratic regression orthogonal design with recommended fertilization of nitrogen, phosphorus and potassium as study object, analyzes the yield of Liriope spicata var. prolifera Y.T.Ma systematically, and built regression models between fertilization and yield. The results indicate: Nitrogen and potassium fertilizer all effect yield markedly, while the effect of phosphorus fertilizer is not obvious. The effect of interaction of nitrogen fertilizer and potassium fertilizer on yield appears a replacement relationship, The yield increasing with the rising use of nitrogen on lower phosphorus level, whereas declining. The combination of high nitrogen, high potassium and low phosphorus can realize high yield. |
