| 摘 要： | 以玉米品种正大999和黔单100为试验材料，利用裂区试验设计，研究品种和种植密度对玉米产量的影响。结果表明：在5种不同栽培密度中，以3168株／667m2产量最高，3669株／667m2次之，其后是2835株／667m2和2501株／667m2，以2168株／667m2最低。通过多重比较表明，3168株／667m2有极显著高于其他密度处理。黔单100产量高于比正大999，差异显著。

| Abstract: | Maize varieties Zhengda999 and Qiandanl00 as test material, split plot design was applied on the effect of variety and planting density on yield of maize. The results showed that the yield ranking of planting density were 3168 plants/667m2, 3669 plants/667m2 ,2835 plants/667m2, 2501 plants/667m2, 2168 plants/667m2 respectively. The yield of planting density 3168 plants/667m2 was significantly higher than others. Yield of Qiandan100 was significantly higher than Zhengda999. |
