种植方式和密度对高产玉米产量及相关性状的影响

Effect of Cultivation Methods Patterns and Plant and Density on Yield and Related Traits of Maize

通过对不同种植方式及密度下3个玉米品种的产量及相关性状进行比较分析。结果表明,穴三株种植方式可以改善玉米的群体结构,提高光能利用率,补偿株间矛盾损伤,提高了产量;品种和种植方式之间存在明显的互作效应,穴三株方式下,登海601的单株地上部生物产量和经济产量最高,分别为418.90g和233.68g。

The yield and its correlation traits of three maize cultivars in different cultivation methods and density were ana- lyzed. The results showed that the community construction was improved, utilization ratio of light energy was improved, the competition among individuals reduced under three plants per hole. So it could efficiently improve yield of maize.The result showed that there was obvious interact effect between cultivation methods and maize cultivars.The biological yield and grain yield of DH601 were higher in three plants per hole method, which are 418.90g and 233.68g respectivelly.
