摘　　要：2008年在郑州市进行了郑黄糯2号密度试验,通过对生育期、植株性状、穗部性状、产量和子粒品质分析比较,结果表明:密度对郑黄糯2号产量和子粒品质影响显著。随着种植密度的增加,郑黄糯2号产量先升后降,郑黄糯2号蛋白含量先上升,然后趋于平稳,油分含量呈下降的趋势,淀粉含量变化无规律。为该品种大面积生产提供科学依据。The field experiments of different density of waxy corn variety ZhenghuangnuoNo.2 were done at Zhengzhou in 2008. Comparison analyses were carried out by different density during the growing time, the traits of plant and ear, yield, quality. The results showed that the density had a significance effect on yield and quality. The yield was increased with densities increasing when the density is less than 90 000 plants. Protein content was increased, oil content was fall down with densities increasing, starch content not obvious. The results gave some scientific basis for the popularizing of this variety in a larger scale.
