Abstract：Sabina chinensis was transplanted in earthen pots with drainage hole to examine the effect of A (field soil),B,C,D,E,F,G,H or I substrates (the cultivation substrates mixed with field soil,sand,chicken manure,corncob and peanut shell in the different proportions of volume) on the tree diameter,number of branches at the top,the contents of chlorophyll,malondialdehydc (MDA),proline(Pro) and soluble sugar.Results showed that the growth rates of tree diameter,the number of branches at the top (including the first branch,the second branch,third branch),the contents of chlorophyll,pro and soluble sugar of S.chinensis cultured with B,C,D,E,F,G,H or I substrates mixed with agricultural waste in varying proportions were diverse from each other,while the values of these parameters were all higher than those of substrate A (field soil).MDA contents were also different from each other,but they were lower than that of substrate A.Cluster analysis revealed that nine cultivation substrates were divided into three categories:the most suitable substrates for S.chinensis growth were H,G,F,the moderate substrates were I,E,D,and the worst were C,B,A.The evaluation by membership function method indicated that the growth status from strong to weak of S.chinensis cultivated with nine different substrates followed by H,G,F,I,E,D,C,B,A.Therefore,among nine different substrates,H mixed cultivation substrate in the proportion of 1.0∶0.5∶1.5∶1.5∶1.5 with field soil,cinders,river sand,chicken manure,corncob and peanut shell was the most suitable for S.chinensis growth,followed by substrate G and F,then followed by substrate I,E,D,C,B,and the worst was field soil.
