玉米种植密度与产量及穗部性状相关性分析

Analysis of Correlation between Planting Density and Yield and Ear Characters of Maize

该试验研究了不同种植密度对玉米产量以及穗部性状的影响,进一步对影响玉米产量的主要穗部性状进行相关分析与通径分析,将穗部各性状与产量的效应分解为直接效应与间接效应,明确各穗部性状在产量构成要素中的相对重要性,为该品种的高产栽培提供理论依据。

The experimental study on the different planting density on corn yield and the effect of panicle traits,further influence the production of corn for several main panicle traits,correlation analysis and path analysis of panicle traits and yield effect is decomposed into direct effect and indirect effect,clear the panicle traits relative importance in yield components,provide theoretical basis for the varieties of high-yield cultivation.
