Through Ulmus pumila cv.’Jinye’ container-growing seedling cultivation experiment with 4 types of media or 9 media formulas,the seedling height,the stem and crown diameter indexes of *** *** were *** indexes were significantly or extreme significantly different among various *** growth of seedling root system varied with different *** rooting and root number in soft media were much better than that in dense *** to the growth traits of above-ground and underground parts of *** *** seedlings,the medium suitable for *** *** seedling growth was defined as media type I,whose ratio of C/N was 17.7—18.1,the density was higher than 0.26 g·*** on this medium,the height,stem diameter and crown diameter of *** *** were 1.34—1.57 m,1.36—1.50 cm and 59.6—73.9 cm,*** results of experiment showed also that the physical property played an active role in cultural media,so a good initial medium could provide great assistance of fertilization and water management in seedling culture.
