摘    要:2005年在郑州对糯玉米品种“郑黑糯1号”分6个不同密度进行试验,通过对不同密度的生育期、株高、鲜果穗性状与品质、鲜穗产量、干籽产量分析比较,结果表明:若以收获鲜穗为目的,郑黑糯1号适宜种植密度为6~6.75万株/hm2;若以收获干籽为目的,适宜种植密度为6.75~7.5万株/hm2,为该品种大面积推广应用提供了一些科学依据。

关 键 词:糯玉米  郑黑糯1号  种植密度  产量

Abstract:The field experiments of different density of waxy corn variety "ZhengheinuoNo1"were done at Zhengzhou in 2005.Comparison analysis were carried out by different density during the fresh-ear harvest fresh times, plant height, the trait and quality of fresh-ear, output of fresh ear. The results showed that if the harvesting fresh-ear was taken as planting object, the optimum planting density of waxy corn variety "ZhengheinuoNo1"should be between 60000 plants/hm2 to 67500 plants/hm2, if the planting abject was harvesting dry kernel, the optimum planting density of waxy corn variety "ZhengheinuoNo1"should be between 67500 plants/hm2 to 75000 plants/hm2. The results gave some scientific basis for the popularizing of this variety in a larger scale of Henan Province.
Keywords:Waxy corn   ZhengheinuoNo1   Optimum planting density   yield
