The spatial distribution characteristics and growing dynamics of the root systems in a apricot and alfalfa sod-culture system were *** results showed that the vertical distribution of the 4-year-old apricot root system could reached to the depth of 100 cm,and roots of some 46.5% distributed in the layer of 20～40 *** vertical distribution of the 2-year-old alfalfa roots could reached to 50 cm depth,and the roots of 70% distributed in the layer of 0～20 *** results suggested the root distribution of the two species did *** horizontal distribution of the apricot root system could reached to 200 cm,and more than 90% roots distributed in the distance of 100～150 cm where management measures were always performed in both sod-culture or control *** addition,two obvious growing peaks of new roots of ’Jintaiyang’ apricot tree were *** was from March to April and the other was from middle of June to early *** growing peak of alfala roots appeared in middle of *** period of the active growth for the two species did not meet together *** to their growing characteristics ’Jintaiyang’ apricot trees should be fertilized in the early March and middle June.
