根据测土掌握玉米播前氮、磷、钾土壤养分状况,通过夏玉米配方、常规、空白“三区”的不同处理的田间试验,为豫西南砂姜黑土土质夏玉米的高产高效提出科学合理的施肥建议,以供参考。
According to soil testing to know the nutrient status of nitrogen, phosphorus and potassium in maize before sowing, the field experiment of different treatment with summer maize formula, conventional and blank “three districts ” was put forward for the high yield and high efficiency of summer maize Scientific and rational fertilization recommendations for reference.
