陕西洛南小麦行套高产栽培技术初探

A Test on Wheat Intercropping in Luonan of Shaanxi

选取对洛南小麦产量影响较大的品种、播量、施肥量、覆盖方式四因子,进行配套栽培因子试验。结果表明,在试验设计条件下,影响小麦产量的因素为播量>施肥量>覆盖方式>品种。初步确定洛南县小麦行套种植的最佳因子处理组合为A1B2C2D2,即品种陕麦150,播量240万粒/hm2,施肥量P2O5135+N180kg/hm2,种植方式为地膜覆盖。

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.
