| 摘 要： | 用Ａｌ２（ＳＯ４）３和Ｈ２ＳＯ４作为酸化剂对拟植茶园的中偏碱性土壤进行土壤酸化试验，结果表明，两种酸化剂均能迅速酸化土壤，Ａｌ２（ＳＯ４）３的酸化效果高于Ｈ２ＳＯ４，前者能使土壤ｐＨ值明显下降，交换性酸总量显著上升。经淋洗后，交换性钙、镁含量明显下降，交换性钾、锰含量变化不大

| Abstract: | The light alkaline soil of pre founded tea gardens was treated by aluminum sulfate Al 2(SO 4) 3]and sulfuric acid (H 2SO 4).Both acidants acidified the soil rapidly,and the acidifying ability of Al 2(SO 4) 3 was stronger than that of H 2SO 4.The soil pH value decreased and the soil exchangeable acid quantity increased significantly with the Al 2(SO 4) 3 treatment.Quantities of exchangeable calcium and exchangeable magnesium decreased significantly,but those of exchangeable potassium and exchangeable manganese remained almost the same after the leaching. |
