| 摘 要： | 目的]解决济宁市小麦/玉米两熟区传统耕作方式生产成本高,对土壤结构破坏大,土壤的生产能力降低的难题。方法]多次试验示范和总结。结果]构建农机农艺技术流程为"小麦联合收获(秸秆粉碎覆盖)→玉米直播→喷除草剂→田间管理(灌溉、灭虫等)→玉米收获并秸秆还田覆盖→深松(3~5年深松一次)→小麦免耕施肥播种→田间管理(灌溉、除草、灭虫等)"的适合该区保护性耕作的技术模式,通过万亩试验示范验证,该保护性耕作技术模式在确保粮食稳产增产的前提下,能够较大幅度降低生产成本。结论]该研究可为济宁市保护性耕作技术的大面积推广奠定基础,应加快推进全市农业进入保护性耕作的新阶段。

| Abstract: | Objective ] The aim was to solve the problems such as high production cost, severe soil structure destroying and Oegradlng ot tra-ditional planting patterns in wheat/corn double-crop annually rotate in Rencheng District, Jining City. Method ] Several trial and demonstra- tion, and summary were conducted on. Resuh] The proper planting processes combining agricultural machinery with agronomy was construc-ted. This process started from wheat combine harvest and straw crushed mulching, contained corn seeds sowing directly, spraying weedkiller, field management, corn harvest and straw crushed mulching, subsoiling（ once time every 3 -5 years）, wheat no-tillage and fertilizer sowing, and new field management. After ten thousand mu test demonstration verification, this planting patterns significantly reduced the production cost under the premise of ensuring the grain production stable and increased. Conclusion] The study lays a basis for promotion of conservation tillage technology patterns in a large scale in Jining City, so it is necessary to advance the whole city＇ s agriculture into a new stage of conser-vation tillage. |
