Abstract: In order to explore the suitable substrate ratio in strawberry cultivation,the strawberry variety Hongtaihou was used as the experimental material to observe the effects of different proportions of carbon residue and soil mixed as the substrate on the growth of potted strawberry.The results showed that when 50%carbon residue and 50% soil were used as substrate,strawberry grew better,and the number of leaves,petiole length,leaf area,plant dry（fresh）weight,root length,chlorophyll content and soluble solid content were better than other treatments.
