| 摘 要： | 研究种植密度对两个玉米品种郑单958和先玉335抗倒性和产量的影响。试验结果表明,随着密度的增加,倒伏率逐渐增高,先玉335的平均倒伏率大于郑单958;玉米株高、穗位高、穗高系数均随着密度的增加逐渐升高,且与倒伏率呈显著或极显著正相关;随着密度的增加,两个玉米品种的产量表现先上升后下降的趋势,在7.5万株/hm^2时产量达到最高。倒伏率与产量相关分析表明,郑单958和先玉335的倒伏率与产量均呈显著负相关。

| Abstract: | The effects of different planting densities on lodging resistance and yield of maize varieties Zhengdan 958 and Xianyu 335 were studied.The results showed that the lodging rate of two maize varieties increased with the increase of density.The average lodging rate of Xianyu 335 was higher than that of Zhengdan 958.The plant height,ear height and ear height coefficient of maize increased gradually with the increase of density,and showed a very significant positive correlation.The yield of the two maize varieties increased first and then decreased,and reached the highest yield at 75,000 plants per hectare.The results of correlation analysis between lodging rate and yield of two maize varieties showed that the lodging rate of Zhengdan 958 and Xianyu 335 were significantly negatively correlated with yield. |
