摘要：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 U.pumila cv.jinye were measured.These indexes were significantly or extreme significantly different among various media.The growth of seedling root system varied with different media.The rooting and root number in soft media were much better than that in dense media.According to the growth traits of above-ground and underground parts of U.pumila cv.jinye seedlings,the medium suitable for U.pumila cv.jinye 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·cm-3.Grown on this medium,the height,stem diameter and crown diameter of U.pumila cv.jiny were 1.34—1.57 m,1.36—1.50 cm and 59.6—73.9 cm,respectively.The 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.
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 U. measured. These indexes were significantly or extreme significantly different among various seedling pumila media. cv. jinye were The growth of root system varied with different media. The rooting and root number in soft media were much better than that in dense media. According to the growth traits of above-ground and underground parts of U. pumila cv. finye seedlings, the medium suitable for U. pumila cv. finye 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·cm^-3. Grown on this medium, the height, stem diameter and crown diameter of U. pumila cv. tiny were 1.34--1.57 m, 1.36--1.50 cm and 59.6--73.9 cm, respectively. The 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.
