| 摘 要： | 为控制土壤酸化对马尾松林的危害，本文通过马尾松幼苗盆栽的试验方法研究了3种土壤处理剂(石灰、泥炭和磷酸盐)对重庆南山酸性土壤的特性及马尾松幼苗生长的影响。结果表明，石灰、泥炭和磷酸盐的单独和复合处理均能明显地提高土壤pH值，降低土壤活性铝含量，增加土壤活性钙和有效磷的水平，土壤处理还明显有利于马尾松幼苗的生长。3种处理剂中以石灰的改良效果最佳。5种处理组合中以石灰－泥炭－磷酸盐结合处理的作用最强。

| Abstract: | The effects of the soil anti-aluminium treatment in the region of serious acidic rain onsoil characteristics and the growth of Pinus Massoniana seedings by soil pot experiment with thesingle or complex treatment of three kinds of material(lime, peaty soil and K_2HPO_4)were stud-ied.The results show that the active aluminum is reduced;the effective calcium and phosphorasare increased in the soil; and the growth of pine is accelerated.The most effective improving material is lime. The treatrnent of limepeaty soil-K_2HPO_4 is the best in the five treatment groups. |
