摘要
为指导上等田玉米合理施肥,进行了不同配方田间试验。结果表明:玉米施用N 20kg/667m2、P2O510kg/667m2、K2O 16kg/667m2产量最高,为798.9kg/667m2,净产值为1 923.33元/667m2,养分增产量为7.51kg/kg。
In order to guide the fertilization on maize in upper level field,different formula fertilization were applied.The results showed that the yield of fertilization at N 20kg/667m2,P2O510kg/667m2,K2 O 16kg/667m2 was the greatest,it's 798.9kg/667m2,the net output was 1923.33Yuan/667m2,input/output ratio of increasing yield was 7.51kg/kg.
