【摘要】 选择普通株型的玉米品种农大108,在设置固定的3种密度前提下,通过调整株行距种植比例,探索不同密度产量水平的变化规律。试验结果表明:高密度的产量较低密度下有较大的增产,大小行种植对于普通株型的农大108来说,产量没有明显的变化,产量与密度有密切相关性,与种植模式没有太大的关系。更多还原

【Abstract】 The selection of the maize plant species common Nongda 108,in the provision of the premise of three kinds of density,by adjusting the proportion of plant type to explore the different levels of density changes of output.The experimental results showed that:high-density production of lower density had a larger output,the size of plant type for a general line of the plant Nongda 108 for no apparent changes in production,yielda nd density were closely associated with the plant model did not obviously relationship.更多还原
