Objective In order to screen out a suitable mixed substrate, study on the effects of different mixed substrates on Cerasus campanulata cortainer seedling was carried out by using the one-year-old seedling as material.

Method The study set up five kinds of mixed substrates consisting of nursery soil, peat soil, coir dust and perlite, and compared survival rate and growth indexes of C. campanulata container seedlings.

Result Four mixed substrate combinations(nursery soil + perlite, peat soil + perlite, coir dust + perlite and nursery soil + coir dust + perlite)had no significant different effects on the ground diameter, plant height, branchlet length and crown width of C. campanulata container seedlings, but the survival rate of C. campanulata after being transplanted for one year under coir dust + perlite treatment was only 66.7%, significantly lower than that of other combinations(≥ 80%). The survival rate of C. campanulata container seedlings treated with "nursery soil + peat soil + perlite" was up to 100%. After one year of transplanting, the ground diameter, plant height, branchlet length and crown width of C. campanulata container seedlings increased by 5.63 mm, 105.46 cm, 68.61 cm and 70.00 cm, which were significantly higher than those of other treatments.

Conclusion According to the evaluation of fuzzy membership function analysis method of under the experimental environment, the best mixed substrate for the one-year-old container seedlings of C. campanulata is V _{nursery soil} : V _{peat soil} : V _perlite = 1:1:1.
