In order to improve the reutilization rate of rubber seedling-stock shoots waste and minimize the burden on the ecological environment, we investigated physicochemical property of rubber nursery plants biochar and its effect on growth of Hevea seedlings. The results showed that sand bed seedlings biochar had the smaller stem diameter, the more N and P content but the less K content and soluble sugar, in comparison with polybag budding biochar and polybag seedling biochar. Stem of polybag budding plants as nutrient medium had less pH value and more electrical conductivity than that of seedling plants biochar. Medium in N and K nutrient were negatively correlated (P<0.05) with plant height, stem diameter and leaf whorls of rubber seedlings. Taken together, stem biochar as nutrient medium was better than leaf tissue powder as nutrient medium for the growth of rubber seedlings.
