Abstract

A randomized block field experiment was carried out from 2005-2008 (a rotation period) to study the changes of soil nutrient contents in three soil layers (0~20 cm, 20~40 cm and 40~60 cm) of the triploid Populus tomentosa(cv. B304) plantations with five stand spacings (2 m×2 m, 2 m×3 m, 2 m×4 m, 2 m×5 m and 3 m×4 m). The results showed that: (1)Soil pH value increased under different stand spacing after the 4-year growing, especially in low-density plantations (3 m×4 m) and deeper soil layers. (2)The contents of soil organic matter decreased at first and then increased. In the high-density plantations (2 m×2 m and 2 m×3 m), the contents of soil organic matter were significantly lower than that of the others. (3)The contents of soil total P and available P increased at first and then decreased. The available P in the plantation with stand density of 2 m×2 m was significantly lower than that of the others. (4)Significantly higher soil available N content was found in the plantation with stand density of 2 m×2 m while significantly lower available K in the middle-(2 m×4 m) and low-density (3 m×4 m) plantations. No regular variation was found in the contents of the other soil nutrients.
