Abstract
As the application of agricultural mechanized production technology becomes more and more extensive, the application of mechanized straw returning technology has become more and more valuable. The mechanized return of straw to the field is a time-saving and labor-saving technology. It is an effective way to achieve sustainable agricultural development and is of great significance to the development and progress of modern agriculture. This article analyzes the current research status of mechanized straw returning to the field, discusses the process structure and characteristics of different mechanized straw returning methods, and focuses on the analysis of the composite technology of straw returning to the field. At the same time, the key problems of straw returning to the field, such as the length of straw not meeting the standard, the shallow depth of straw returning to the field, and the uneven distribution of straw, are put forward and analyzed. By taking the cover and burial rate of straw on the soil surface and the spatial distribution uniformity of straw in the soil as the performance evaluation indexes of straw mechanized field return, each index is elaborated. Finally, two major development trends are proposed: the development of mechanized straw returning to the field from a single process to a composite process, and the effect of straw returning to the field towards uniform mixed burying and precise control.
