Abstract: Varieties, sowing norm, fertilizer and film mulching were selected in the test. The effect sequence of four factor on wheat yield was showed in high soil rapidly available nitrogen and low rapidly available phosphorus: sowing norm>fertilizer >film mulching>varieties. It was showed that the cultural scheme of optimum yield: variety was Shaan Mai 150, sowing norm was 2.4×106 kernels/ hm2, fertilizer was P2O5 135+N 180 kg/hm2, cultural method was film mulching.
