Abstract
This study evaluated the effects of biochar application on sodium ion accumulation, yield and quality of rice in saline-sodic soil by using a pot experiment. Rice was grown in the soil with no biochar, 15 g biochar per kilogram soil, 30 g biochar per kilogram soil and 45 g biochar per kilogram soil. The results indicated that biochar application significantly decreased sodium ion accumulation of rice plant parts, while it obviously increased rice dry biomass, grain yield and improved rice quality. The results suggested that biochar application to saline-sodic paddy soil has benefits to reduce stress and promote the increase of rice yield and quality formation in saline-sodic soil.
