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、P2O58kg/667m2、K2O15kg/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1 069.7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%。
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
