小麦秸秆还田及免耕播种机械化技术

Mechanization Technology of Returning Wh eat Straw to field and No-Tillage Sowing

对小麦秸秆还田及免耕播种机械化技术进行系统分析,论述了秸秆机械化还田的两种主要方式,重点阐述了小麦秸秆机械化粉碎翻压还田技术。总结了稻麦、麦玉米周年生产的机械化作业技术路线,明确了技术实施过程中对田块、机械和操作人员的要求。提出了深旋耕密实镇压联合整地作业以及小麦宽幅精量单行镇压播种模式的优化策略。探讨了强化技术推广的策略,包括技术宣传、政府投入和推广示范,以期推动小麦秸秆还田及免耕机械化播种技术的普及应用。

the mechanization technology of returning wheat straw to field and no-tillage sowing was systematically analyzed,two main ways of mechanized straw returning to the field were discussed,and the mechanized wheat straw crushing and over-pressing technology was introduced.By summarizing the technical route of rice,wheat and corn annual production,the requirements of field,machinery and operators in the implementation process were clarified.The optimization strategies of the combined land preparation operation of deep rotary tillage and compaction suppression and the single row suppression seeding mode of wheat with wide precision were put forward.Strategies to enhance technology dissemination including technology dissemination,government input and demonstration were discussed to promote application of mechanization technology of returning wheat straw to field and no-tillage seeding.
