| 摘 要： | 以西辽河平原主推品种郑单958、先玉335、金山27和伟科702为试验材料,研究玉米农艺性状对种植密度的响应.结果表明,随着玉米种植密度增加,4个品种的株高和穗位高均先升后降,在密度9.0万株/hm2时达到最大.株高以先玉335最高,其它3个品种差异不大.穗位高金山27最高,伟科702最低.穗位节节间先玉335最长,其它3个品种相差甚微.各品种茎粗均随种植密度增加而减小. |

| Abstract: | Four different main varieties in the West Liaohe plain,which were Zhengdan958,Xianyu335,Jinshan27,and Weike702 as materials,were used in this study to test the responses of maize agronomic characteristics to density.The results showed that with the maize planting density increased, 4 varieties of plant height and ear height were both fall after rise,the maximum height occurred in 90,000 plants /hm2. The Xianyu335 had the highest plant height, and had a few differences with other three varieties. However,Jinshan 27 had the highest ear height, the ear height of Weike702 was the lowest. Xianyu335 had the highest ear longth,but the other three varieties had a little differences. The stem diameter decreased with the increased planting density. |
