Abstract: In order to study the difference of soil nutrient elements distribution characteristic between different‘Fuji’apple orchards with various soil texture and tree age. Take full fruit and sapling period orchards respectively with loam, sandy and clay soil as research objects. Analyze for organic matters and nutrient elements (N, P, K, Ca, B, Mg) in 0-20 cm and 20-60 cm depths soil layer. The result showed that: (1) The content of organic matters and nutrient elements in full fruit period orchards was high than in sapling. (2) There were great differences in element content between various soil texture and tree age orchards. Loam and clay soil had same distribution regularity. (3) There were some difference of elements content between soil layer, especially soil organic and B, reached significant difference. (4) The apple orchard soil and fertilizer management in Akesu prefecture should pay attention on increasing organic fertilizer nitrogen and boron elements application. The management of sand orchard should also increase calcium fertilizer and magnesium fertilizer.
