不同品种和密度对玉米产量的影响

The Effects on Yield of Planting Density of Different Maize Varieties in Tacheng

本文分析了新疆塔城市3个玉米品种在不同种植密度下的农艺性状和产量差异。结果表明,常规品种先玉335、郑单958在栽培密度为5000株/667m^2的条件下有较好的表现,但密度进一步增加,倒折风险很大;和育187在5000株/667m^2的栽培密度条件下产量最高,适宜的高密度有进一步提升产量的潜力。

This paper analyzed the differences in yield and its agronomic traits on different plant densities of 3 kinds of maize varieties in Tacheng city,Xinjiang.The result showed that Xianyu335 and Zhengdan958 had better performance under cultivation density of 5000plants/667m^2,but further increase on the desities could cause a high risk of tipping.The yield of Heyu 187was the highest under the same condition,and with the further increase on plant desities may increase the yield.
