Sp lit-p lot field experiment with 2-year-old trip loid Populus tom en tosa clone S1, S6, S8 and S11 asexperimental materials and dip loid clone S10 as control was carried out in Wei County, Xintai City, HeibeiProvince. Annual change of soil nutrients in different p lantation and tree growth indices of height, DBH and volumewere determined. The results showed that soil pH increased and the content of organic matter decreased obviously ina year. Total N, available N, total P, available P, and total K decreased to some extents, while no regulation wasfound for available K. Different clones had no significant effect on the decline of the soil nutrients. Compared withthe control S10, the trip loid Populus tom entosa grew much better and took up more soil nutrients, with S8 as thebest and followed by S1 and S6.
