Abstract: In this paper,researches were conducted on five different nursery substrata of Spathodea campanulata seedlings growth,biomass and root shoot ratio.The results showed that 5 kinds of different substrata had significant effects (P<0.01) on the seedling height,diameter,root length,fresh quality and underground parts of the fresh weight of Spathodea campanulata for each treatment.As for seedling height,diameter,root length,underground fresh quality and fresh weight of growth performance,a better matrix formulation was the mixed matrix of 3/5 bagasse,1/5 needles and 1/5 cow dung.And the effects of other recipes of nursery substrate on seedling height,ground diameter,root length,underground fresh quality and response of the fresh matter were not consistent.
