摘要
我国东北黑土区侵蚀严重,为找到控制水土流失的有效途径,分析了美国实施保护性耕作的实践经验,阐述了其发展概况、作用和实践中遇见的问题,具体介绍了美国保护性耕作中免耕(含条耕、带耕、垂直耕)、覆盖耕、垄耕等几种常见耕作模式和相关机具。对我国东北黑土区耕地保护途径的选择、保护性耕作的理解、耕作模式改革创新、秸秆还田、深松施肥和防治病虫草害具有借鉴意义。
The black soil layers in the northeast of China undergo serious erosion.In order to seek an effective way to control soil and water loss in the area,the practical experiences in conservation tillage in the United States were introduced for analysis including the general situation of development,effects and challenges encountered.Popular modes there such as no tillage,strip tillage,zone tillage,vertical tillage,mulch tillage,and ridge tillage as well as the related implements were outlined.That is helpful for understanding conservation tillage itself,handling residue management,deep chiseling and pest or weed control.That may also serve as references while making reform and innovation of tillage modes and selecting tillage soil protection measures in the northeast of China.
