In this test,the weight of growth index for camphor was evaluated by using the coefficient of variation,and the composite growth index of camphor in different matrix formulations was calculated,and the Taguchi method and matrix environmental safety evaluation were used to optimize the camphor base formula.The results showed that，among the growth index for camphor，fresh weight of new roots was the highest；except for matrixes of No1,7,18,29,the composite growth index of camphor from different matrix formulation was higher than that of the control group,furthermore,the difference between the matrix of No2,8,13,16,20～25,27,28 and control group was significantly（P<0.05）.The effect of sewage sludge compost,vermiculite and the interaction between sewage sludge compost and fungicide on composite growth index for camphor reached significantly level.In addition to polyaspartic acid,the remaining components of matrix also facilitated the growth of camphor,but none of them was significant.Cd contamination in soil might be caused by the using of sewage sludge compost when the level was 3.0 kg and 4.5 kg.In conclusion,the best matrix formulation was composed of sewage sludge compost,fungicide,compound fertilize and vermiculite with the level of 15 kg,03 g,20 g,100 g respectively.The accuracy and reliability of the screening test model for matrix formulation was verified by the predictive analysis system of Taguchi method in Minitab software.
