摘　　要：近年来,油—稻免耕直播栽培技术以其节本高效等优势得以迅速推广。对油—稻免耕直播栽培技术的详细操作流程、产量及经济效益进行了实地调查及分析。结果表明:油—稻免耕直播的油菜产量较油—稻旋耕直播仅减少3.8%,但水稻产量增加5.6%,且较冬闲—稻免耕直播增加13.7%;油—稻免耕直播的总成本较油—稻旋耕直播减少12.0%,净收益增加18.3%;油—稻免耕直播、油—稻旋耕直播的净收益较冬闲—稻免耕直播分别增加58.1%和33.6%。表明冬种油菜可有效增加稻田系统的农民收入,且油—稻免耕直播可作为今后重点推广的一种水旱轮作节本增效模式。In recent years, no-tillage and direct seeding cultivation technology of rape-rice has been developing rapidly with its advantages of cost-saving and high efficiency. The detailed operation process, yield and economic benefit of no-tillage and direct seeding cultivation technology of rape-rice were investigated and analyzed in order to provide some technical support for reducing cost and increasing The results showed that rape yield under no-tillage and direct seeding of rape-rice decreased by only 3.8% compared with that under rotary tillage direct seeding of rape-rice, but rice yield increased by The total cost of rape-rice no-tillage direct seeding was 12.0% lower than that of rape-rice rotary direct seeding, and the net income increased by 18.3%. The net income of rape-rice no-tillage direct seeding and rape-rice rotary direct seeding increased by 58.1% and 33.6% respectively, compared with that of no-tillage direct seeding of winter fallow-rice. The results showed that winter rape planting could effectively increase farmers’ income in paddy field system, and no-tillage direct seeding of rape-rice could be used as a cost-saving and efficiency-increasing mode of water-dryland rotation in the future.
