Three procedure treatments (A. base medium + non-woven fabrics + culture medium + seeds + nylon net + base medium;B. base medium + non-woven fabrics + base medium + seeds + base medium;C. base medium + river sands + base medium + seeds + nylon net + base medium)were used for sod production in Lanzhou. The results showed that the underground phytomass within 0 to 5 cm in Group C was higher than Group A and B,and no significant difference among rest groups. The strength of Group C was the highest and Group B was the lowest. The breakage rate of Group B was the highest,and it was zero for Group A and C. The difference of sod weight per unit volume was not significant among 3 groups. Based relational grey analysis,sod quality sequence was C＞A＞B.
