| 摘 要： | 为明确磷肥施用量对玉米数量性状的影响，在云南高原红壤旱坡上平衡施用N、K、Mg、Zn的基础上，对玉米籽粒产量、单株籽粒产量、穗位叶面积、秸秆产量等性状进行研究。结果表明，玉米籽粒产量、单株籽粒产量、穗位叶面积、秸秆产量对不同施磷量的敏感性较大，变异幅度超过46%；叶绿素含量和株高对磷的敏感性较差，变异幅度不到20%。玉米生物产量因不同施磷效应大致表现2OPT+P > 2OPT > 2OPT-P > OPT > 2OPT-2P > CK。

| Abstract: | Studying on corn quantitative characters such as corn yield,corn yield of single plant,area of ear leaf,and corn straw yield and so on for finding out the effect of different phosphorus fertilizer rates with balanced fertilization of nitrogen,potash,magnesium and zinc on red soil of upland.A field experiment on phosphorus rates was conducted in Yunnan Plateau.Results showed that there was more sensitivity between different phosphorus fertilizer rates and corn yield,corn yield of single plant,area of ear lea... |
