摘要
为确定郑单528玉米品种的适宜密度,对不同种植密度下郑单528的生育期、株高、果穗性状及产量构成因素等进行了分析比较。结果表明,郑单528最佳种植密度为5.25万～6.00万株/hm2,高肥水条件下的最适宜密度为6.75万株/hm2。
A field experiment was carried out in 2009 to find out the most suitable density of new corn variety Zhengdan528.The developmental stages,plant height,ear characters and yield components of Zhengdan528 were analyzed under 7 planting densities.The results showed that the optimum density of Zhengdan528 was 52500-60000 plants/ha,but it could reach to 67500 plants/ha in abundant fertilizer and water conditions.
