密度和肥料对高油玉米生理性状的影响

Effect of density and fertilizer on physiological characteristics of high-oil maize

研究不同肥料、密度下高油玉米的叶绿素、NRA、光合作用和氮、磷、钾变化情况,结果表明,肥料和密度对高油玉米的叶绿素、NRA、光合作用和氮、钾都有显著的影响。其中密度为52500株/hm2,施肥量为N:360kg/hm2、P2O5:120kg/hm2、K2O:180kg/hm2的表现最好。

With different planted density and fertilizers, the changes of the chlorophyll N, P and K in content, the NRA activity, the photosynthesis in hlgh-oil maize were studies. The results indicated that the density and fertilizer had obvious effects on the chlorophyll, the NRA activity, the photosynthesis, the N, P and K of the maize. With the density of 52 500 plants/hm^2 and the fertilizer delivery of N of 360 kg/hm^2 ,P2O5 of 120 kg/hm^2 ,K2O of 180 kg/hm^2, the performance of the crop was the best.
