摘要
种植密度、株行距配置直接影响到玉米的产量.在密度6.0、7.5、9.0万株/hm23个水平下,以7.5万株/h㎡的产量较高;在蜂巢式结构、常规种植、宽窄行种植、宽窄行穴种双株、宽行穴种三株五种株行距配置方式下,宽窄行表现突出.试验结果表明,7.5万株/h㎡×宽窄行种植处理的产量最高.
Planting density and spacing allocation which have direct effects on maize yield were studied. Concerning three different planting densities(60,000 plants/h㎡,75,000 plants/h㎡and 90,000 plants/h㎡), the highest yield occured at 75,000 plants/h㎡. Among five different spacing allocations(honeycomb type structure , general planting, wide-narrow row planting, wide-narrow row planting with two strains in each hole and wide lines with three strains in each hole), wide-narrow row-spacing planting at 75,000 plants/h㎡provided the highest yield.
