本文阐述了传统耕作法,少耕法和免耕法的基本概念,分析了秸秆覆盖免耕法的原理。夏玉米免耕覆盖种植机械化技术就是应用秸秆覆盖法的原理试验成功的一项科研成果,这项技术由三项作业,六项技术组成,具有节能,省工,增产,增加土壤有机质,改善土壤结构等效益,是对传统耕作法改革的一项新型耕作技术。研制成功的免耕播种机是实现这项技术的关键机具,本文介绍了其工作部件及工作原理。最后指出这项新技术在我国小麦、玉米两熟地区推广应用的意义。
This paper describes the basic concepts of traditional tillage, tillage and no tillage, and analyzes the principle of straw tillage without tillage. Summer maize tillage cultivation mechanization technology is the successful application of straw mulching principle of a successful scientific research, the technology consists of three operations, six technology components, with energy saving, labor, increase production, increase soil organic matter, improve soil The structural benefits are a new type of farming technique for the reform of traditional farming methods. Successful development of no-till planter is the key tool to achieve this technology, this article describes its working parts and working principle. Finally, it points out the significance of popularization and application of this new technology in wheat and corn fields in China.
