摘　　要：为探究玉米适宜的种植方式,以玉米新品系庆301为试验材料,在1m宽垄上种植2行,设4个种植密度,每个密度采用4种行间种植方式,研究密度和种植方式对试验玉米产量的影响。结果表明:在相同的种植方式下,玉米的产量随着种植密度的增加先增加后减少,产量在7.5万株·hm-2时最高;在相同的种植密度下,垄上双行行间距35cm垄距65cm的种植方式最好。最佳的宽垄增行种植模式是密度7.5万株·hm-2、垄上双苗带间距35cm垄距65cm,最高产量1.22万kg·hm-2。In order to explore optimum maize planting ways, taking new maize line Qing 301 as test material, each density adopted 4 row planting pattern,the effect of different planting densities on maize yield in planting 2 rows in 1 m wide ridge was studied. The results showed that in the same planting mode,the maize yield first increased and then decreased with the increasing of planting density, the highest yield in 75 thousand plant· hm^-2; in the same density on the ridge,double rows row spacing 35 cm ridge spacing 65 cm planting way was the best,the highest yield was 12.2 thousand kg·hm^-2. The optimum model was density 75 thousand plant· hm^-2 and double rows row spacing 35 cm ridge spacing 65 cm planting way.
