Abstract: In order to further improve the economic efficiency of cotton fields and ensure the stability of cotton planting area，adapting to local conditions，changing the cotton cultivation technology，choosing the appropriate planting structure and crop layout have become important measures to promote the high⁃quality development of cotton production.Among them，the theoretical research and application of intercropping patterns in cotton fields have received wide attention.In view of the current research，the main intercropping patterns in cotton fields at home and abroad were summarized，and the advantages of various intercropping patterns in terms of yield increase were summarized.The effects of intercropping patterns on growth and development，photosynthetic characteristics，nutrient uptake and utilization，root morphological characteristics，yield and quality of cotton and soil physical and chemical properties were described.At the same time，the prospect of the application of intercropping patterns was made according to the current problems in the actual production of cotton.This paper will provide reference for future research on the application of intercropping patterns in cotton production in China.
