| Abstract: | An evaluation of the impact of scattering limestone powder on acidified soil surface on the growth of young trees of Schima superba under crowns of a Pinus massoniana plantation (three years and four months after treatment) were made by a long-term field fixed position experiment, which was conducted in the Tieshanping Forest Farm of Chongqing City in 2004. The randomized complete block experiment had five treatments and three replicates: the doses of one-time scattering of 0 (control), 1, 2, 3 and 4 t·hm-2 finely ground limestone respectively. The effect was significant: surface limestone could ameliorate health condition of the young trees of S. superba and among them the optimum dose was 2 t·hm-2. The mean canopy thickness, crown size, height and diameter of the base at 20 cm above the ground of the young trees of S. superba treated by 2 t·hm-2 increased by 96.84%, 52.68%, 77.47% and 61.19% respectively (P<0.05) compared to the control. |
