玉米宽窄行种植模式下肥密互作效应的研究

Studies on Interactive Effects of Density and Fertilizer of Planting Technique with Wide/Narrow Row Alternation for Maize

通过研究在宽窄行种植条件下郑单958的种植密度与施肥量的互作关系。结果表明,在高密度条件下,随着密度的增加对施肥量有更高的要求。在当地合理的种植密度为6万株/hm2,产量在7 000 kg/hm2左右,建议公顷施肥量纯N 200～275 kg、P 100～137.5 kg、K 80～110 kg。

Results of research on interactive effects of density and fertilizer of planting technique with wide/narrow row for‘ZhengDan 958’shows that in high density fertilizer was increased with density.In the local area,when proper planting density was 60000 plants/ha and yield was about 7 000 kg/ha,fertilizer of N 200-275 kg,P 100-137.5 kg,K 80-110 kg was suggested.
