The re2 sults showed that the earthworm enhanced the activities of soil urease, acid phosphatase and alkalin phospha2 tase, and increased m icrobiom ass nitrogen in the three kinds of soils, in which the urease activity in brown soil, the alkalin phosphatase activity in fluvo2aquic soil and the m icrobiom ass nitrogen in brown soil increased 7819%, 17010% and 18014% respectively. The treatm ent of earthworm increased the m icrobiom ass carbon in cinnamon soil and fluvo2aquic soil, and the increased degree of that in fluvo2aquic soil is the largest, which reached 29912%. The root activity, root growth and new shoots growth of the app le trees in the soils treated by earthworm increased significantly; The root activity in brown soil, the grow th of root in cinnamon soil and the growth of new shoots in fluvo2aquic soil were the highest respectively in the three kinds of soils treated by earthworm.
