摘　　要：观察了甘谷县冬小麦不同覆膜栽培方式的效果,结果表明,3种覆膜栽培方式均能有效保墒增温,增产效果明显,以全膜覆土穴播的产量最高,较露地条播增产115.6%;全膜不覆土穴播和膜侧沟播分别较露地条播增产61.0%、45.5%。The effect of the different film-covering modes of winter wheat in Gangu county were observed.The results showed that three kinds of cultivation methods can be effective moisture coated warming and increase yield,the yield of hole sowing wheat covering soil in mulched with plastic film was the highest which was 115.6% higher than of the drill seeding in open field.The hole sowing non-covering soil in mulched with plastic film and the furrow sowing in side mulched with plastic film were 61.0%,45.5% higher than of the drill seeding in open field.
