石灰石粉施用量对重庆酸雨区马尾松林下木荷生长的影响
摘要
<正>重庆是我国酸雨发生最早且其污染最严重的地区之一。由于长期遭受酸雨影响,这里的森林受害明显,经济和环境损失巨大。马尾松(Pinus massonianaLamb.)和木荷(Schima superbaGardn.etChamp.)都属于重庆的重要乡土树种,马尾松在造林中被广泛使用,木荷是优良的生物防火树种,并因
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.
