摘　　要：为了达到节本增效,增产又增收,最大限度地降低生产成本的目的,开展了双垄全膜覆盖"一膜两年用"免耕栽培模式下的节本增效研究。结果表明,双垄全膜覆盖"一膜两年用"免耕栽培模式比双垄全膜覆盖沟播栽培(农肥+化肥)模式投产比提高了40.66%,比双垄全膜覆盖沟播栽培(化肥)模式投产比提高了33.33%,比常规半膜覆盖栽培模式投产比提高了36.17%,为大面积推广应用提供科学依据。In order to reduce cost and increase efficiency, increase production and income, minimize production costs, effect of ＂a film with two years＂ no-till planting mode under the condition of double ridges whole film covering was carried out. The results showed that input/output of the double ridges whole film covering % film with two years＂ no-till planting patterns increased by 40.66% than double ridges whole film coveting furrow sowing cultivation pattem （agriculture fertilizer ＋ fertilizer）, and increased by 33.33% than double ridges whole film covering furrow sowing cultivation pattern （fertilizer）, and increased by 36.17% than conventional half film covering cultivation pattern, which provided a scientific basis for large popularization and application.
