不同施氮量与种植密度对玉米盘江7号产量及农艺性状的影响

Effect of Planting Density and Nitrogen Fertilizer Application on the Agronomic Traits and Yield of Panjiang No.7

通过研究不同种植密度和施肥量对玉米盘江7号产量和农艺性状的影响,旨在为盘江7号高产栽培技术提供依据。结果表明,在复合肥40kg/667m^2+过磷酸钙15kg/667m^2为底肥,硫酸钾用量为10kg/667m^2的条件下,盘江7号的最适栽培密度为3600株/667m^2,适宜尿素施用量为45 kg/667m^2。

In order to find out the optimum planting density and rate of fertilizer application for maize variety Panjiang No. 7,the density and fertilizer test was conducted. The results indicated that while the base fertilizer was 40 kg/667 m^2 NPK compound fertilizer ＋15 kg/667 m^2 superphosphate and 10 kg/667 m^2 potassium sulfate fertilizer,the suitable planting density of Panjiang No. 7 was 3600 plants/667 m^2,the appropriate amount of urea was 45 kg/667 m^2.
