Effects of Planting Density and Nitrogen Fertilizer Rate on Accumulated Quantity of Dry Matter and Yield of Spring Maize in Ridge Film Mulching and Furrow Seeding
Maize hybrid Shenhe201 was used as the material, the effects of planting density and nitrogen rateon the accumulated quantity of dry matter and yield of spring maize in ridge film mulching and furrow seeding werecarried out in 2012 and 2014. The results showed that the dry matter accumulation of individual maize decreasedwith increasing of planting density and increased with increasing of N rate at tasselling stage and filling stage, andthat the dry matter accumulation of population increased with increasin...
