Xinjiang is the largest cotton producing area and production base of cotton with high-quality in China， with the planting area and yield ranking first in China. Cotton stalk， as the main by-product of cotton， is an important renewable resource in agriculture， and its value of utilization has attracted more and more attention. The mechanization in recycling cotton stalk is the primary link in the collection， storage， and transportation of cotton stalks， and is a prerequisite for ensuring the comprehensive utilization of cotton stalks out of the field. Solving problems of the mechanization in recycling cotton stalk has important practical significance for improving its comprehensive utilization rate and the ecological environment， and increasing economic benefits. The situation of cotton production and resources of cotton stalk in Xinjiang were analyzed by reviewing the relevant literature， combined with field investigation and project study. The situation of research and application of the typical machinery for recycling cotton stalks at home and abroad was overviewed. The types， key technologies， performance characteristics， problems， and trends of the machinery for recycling cotton stalks in China were summarized. It was pointed out that the low level of mechanization in recycling cotton stalks and the imperfect system of collecting， storing and transporting cotton stalks in China are the bottleneck issues that restrict the comprehensive utilization of cotton stalks at present. It is proposed to strengthen the innovation of the mechanization in recycling cotton stalk and break through the core key technologies. At the same time， the system of the collection， storage， and transportation of cotton stalks should be established and improved. The technology model for recycling and utilization of cotton stalks out of field should be constructed.
