不同种植密度对强盛51号玉米主要农艺性状和产量的影响

Effects of Different Planting Density on the Main Agronomic Characteristics and Yield of Maize with Qiangsheng 51

通过研究不同种植密度对强盛51号玉米主要农艺性状和产量性状的影响,确定最适宜的种植密度,为农业生产和高产栽培提供理论依据。结果表明,种植密度为6.75万株/hm^2时,产量达到最高(13 117.5 kg/hm^2),密度在6.00万~6.75万株/hm^2时产量差异不显著,确定6.00万~6.75万株/hm^2为大田种植的适宜密度;高水肥条件下以6.75万株/hm^2种植密度为最佳。

This paper tries to determine the most suitable planting density through comparing the influences on agronomic characteristics and yield traits of different planting densities of the maize variety Qiangsheng 51, which provides a theoretical foundation for its agricultural production and high-yield cultivation. The result shows that 67 500 plants/hm^2 can achieve the highest yield of13 117.5 kg/hm^2, while there is little difference with the density in 60 000-67 500 plants/hm^2. In this sense, it is concluded that60 000-67 500 plants/hm^2 is the optimal density for field planting, and 67 500 plants/hm^2 is the best planting density in highly water and fertilizer conditions.
