| 摘 要： | 研究不同覆盖栽培方式对马铃薯产量和水分利用效率的影响,结果表明,全膜双垄沟播和垄上覆膜垄沟覆秸秆栽培能显著提高马铃薯的产量和水分利用效率,两处理的产量和水分利用效率较对照分别提高57.79%、36.31%和54.08%、31.42%。土壤贮水量受覆盖栽培方式的影响较大,全膜双垄沟播、垄上覆膜垄沟覆秸秆、麦秸覆盖平作栽培能有效的提高0～110 cm土层的贮水量。

| Abstract: | The effect of mulching methods on yield and and water use efficiency of dryland potato was studied.The results showed that the completely mulched alternating narrow and wide with furrow planting,film-mulched on ridges combined with wheat straw covered in furrow can greatly increase corn yield and water use efficiency（WUE）.Grain yield and WUE was high than conventional treatments as 57.79%,36.31% and 54.08%,31.41%,respectively;Different mulching cultivation methods affected the soil storage,the completely mulched alternating narrow and wide with furrow planting,film-mulched on ridges and wheat straw covered in furrow,the completely mulched wheat straw mulch flat planting can significantly improve 0～110 cm soil water storge. |
