The results showed that the seedlings grown of rape, which was severely affected by Al toxicity in acid soil, was improved by the application of rice straw and green waste compost, and the amelioration of rice straw was better than green waste compost. Compared with the control, the application of rice straw and green waste compost could decrease the content of soil exchangeable Al, increase the soil pH, the content of rape leaf chlorophyll, the activities of peroxides and catalase, thus leaded to the significant higher photosynthesis rate and plant biomass.
