| 摘 要： | 根据山东莱州和河南温县多年进行的夏玉米超高产栽培试验资料，分析了夏玉米产量构成因素以及气象条件与产量构成因素的关系。结果表明：在夏玉米超高产栽培条件下，产量构成因素对产量的贡献大小顺序为穗粒数>穗数>粒重；影响穗粒数的关键气象因子是播种后第6、8旬(从播种期所在旬记起，下同)的降水量和第6旬的日照时数。

| Abstract: | It studied the impact of precipitation difference to leaf area and single trunk dry matter accumulated and output of maize on loess plateau in east of Gansu province. The result shown that, if the precipitation was different, leaf area increase rate was different, dry matter accumulated rate was different and the output was different during maize grow. Especially the precipitation of jointing and heading to leaf area growed, dry matter accumulate and output of maize had bigger impact. |
