Abstract：Some physical and chemical indicators such as density , total porosity , aeration porosity , wa-ter-holding pores, pH and EC value of peat, vermiculite, pearlite, mushroom residue and their compound matrixes in different proportions were analyzed in this article .And their effects on growth of Zhangqiu bunc-hing onion seedlings were also studied .The results showed that the comprehensive physicochemical indexes of single matrix could not well meet the growth demands of bunching onion seedlings , while those of compound matrix were better .Among the 5 tested compound matrixes , the formula of peat∶perlite∶vermiculite as 6∶3∶1 was the best for onion seedling growth .
