Abstract: As mechanization becoming the important development direction of crop production, the solution that seedling technique how to meet with the demands of mechanization has been being the hotspot and difficult problem of cotton cultivation. So briefly the impact of the seedling transplanting on cotton , reviewing the current typical seedling-raising techniques, and comprehensively elaborate domestic and foreign research the progress of crop transplanting mechanization, specially in seedling quality and cotton field demands, and the study and application of transplanting machines. It is pointed out that the main problems, the future tendency and study priorities on the way of seedling-raising and mechanized transplanting for cotton, in order to provide the certain evidences to cotton simplified cultivation.
