| 摘 要： | 在湖南祁阳的红壤稻田进行了26年的长期定位试验，结果表明，多年连续施用含氯和含硫肥料尤其是含硫肥料会造成土壤酸化。Cl^-1易随水流失，长期连续施用不会在土壤中大量残留；而长期施用含硫肥料，SO4^2-在表土层和底土层中有明显的累积，累积的SO4^2-因改变了土壤的化学性质而对水稻生长有显的影响。

| Abstract: | A long term field experiment had been conducted in a red soil in Qiyang from 1975 to 2000.The results obtained were as follows,the soil became more acidic after long term application chloride containing fertilizers or sulfur containing fertilizers.The accumulation of Cl - was much less than SO 2- 4 in the soil because Cl - could be leached easily.The accumulation of SO 2- 4 in the soil profile deteriorated the chemical properties of the soil and thus affected the growth of rice. |
