摘要:

2007年在开封对玉米新品种郑单136分5个不同种植密度进行试验,通过对不同种植密度的郑单136的生育期、株高、果穗性状及产量构成因素等进行分析比较,结果表明:郑单136最佳种植密度为7.5~8.25万株/hm2,为该品种大面积推广应用提供了科学依据。

Abstract:

The field experiments of different density of new corn variety Zhengdan136 were developed at Kaifeng city in 2007.Comparison analysis were carried outon the growing time,plant height,the trait of ear and yield components under different planting density.The results showed that the optimum density of the new corn variety Zhengdan136 is 75000 plants/hm2.The test gave some scientific basis for the popularizing this variety in a larger scale of Henan province.

Key words: corn, zhengdan136, planting density, yield;
