| 摘 要： | 在玉米免耕栽培地，通过设计氮、磷、钾不同肥料配比试验，结果得出：合理的氮、磷、钾肥料配比为施用N12kg／667m2、P2O5 8kg／667m2、K20 15kg／667m2，施肥水平N：P2O5：K2O为1：0．7：1.2时，玉米籽粒产量为465．1kg／667m2，产值为1069．7元／667m2，纯收入为684．9元／667m2，净产投比为2．8：1，肥料利用率分别为氮36．9％，磷9．8％，钾为16．3％。

| Abstract: | Through the designation of different fertilizer allocated proportions of nitrogen, phosphorus and potassium in corn no-tillage field, the results showed that： The proportion of reasonable nitrogen, phosphorus and potassium fertilizer was N 12kg/667m2, P2O58kg/667m2, K2O15kg/667m2, the fertilization level was N：P2O5：K2O= 1：0.7：1.2, the output of corn was 465.1kg/667m2, the value was 1 069.7 Yuan/667m2,the net income was 684.9 Yuan/667m2, the ratio of input and net income was 2.8：1, fertilizer utilization respectively was that： the fertilizer utilization of nitrogen was 36.9%, the one of phosphorus was 9.8%,the one of ootassium was 16.3%o |
