Research progress on ecological effects under the rotational tillage patternsin agricultural regions of China

The soil rotational tillage system with the proper match of different tillage practices could solve all the long-term and continuous single-tillage problems in agricultural regions. This method has attracted attention both at home and abroad.In order to understand the research progress on ecological effects under the rotational tillage patterns in different agricultural regions of China,in this paper,we review in detail the concept,patterns of rotational tillage,and the ecological effects of this system. According to existing data,we summarize the soil rotational tillage pattern types,operation effects,and mechanical choice in different agricultural regions. There is a need for scientific evaluation of the ecological effects on soils and crops under rotational tillage,and there are still a number of unsolved problems in the research on current soil rotational tillage technology; accordingly,we provided some suggestions. It is difficult to study the realistic cycle of rotational tillage; analysis of the resear
