摘　　要：为明确嫩单15的适宜种植密度,发挥群体优势,获得高产,以玉米新品种嫩单15为材料,研究了不同种植密度对嫩单15的农艺性状及其产量的影响。结果表明:随着种植密度的增加,嫩单15的株高、穗位高和秃尖长逐渐增加,穗长、百粒重和单穗重逐渐减少;群体密度6.00万株.hm-2时产量最高,在中等偏上的水肥条件下的适宜密度为5.25万～6.75万株.hm-2。In order to definite the appropriate planting density of Nendan15,give full scope to group advantage and achieve high yield,Nendan15 was used as experiment material to study the effect of different planting den- sities on agronomic traits and yield. The results showed that the plant height,ear height and bare top length increased,and ear length, 100-seed weight, yield per ear decreased with the increase of planting density. The high-est yield was obtained when the density was 60 000 plant.hm-2. The appropriate density was 52 500 to 67 500 plant, hm-2 under the above-average water and fertilization conditions.
