Abstract: The development of straw returning technology in China is mainly divided into three stages, including initial stage, development stage and current stage. In the initial stage of straw returning technology, indirect returning technology such as composting and retting was mainly used, and direct returning technology was relatively weak; In the development stage, the direct straw returning technology became the main returning mode, and the parameters of straw returning technology were preliminarily clear. With the improvement of mechanization, the direct straw returning technology had developed rapidly at this stage. Based on the original straw returning technology, there were new straw returning technologies such as ditch burying and carbonization.

Key words: straw returning to field, soil fertility, direct return to land, returning the indirect
