Abstract
The objective of this study was to determine the release of S in paddy soil. The experiment was carried out in the greenhouse which the soil sample was taken from three different sites. The treatment consists of (T0) control, (T1) 0.02 g S pot-1, (T2) 0.04 g S pot-1, (T3) 0.08 g S pot-1, (T4) 0.04 g S pot-1 + rice straw. The concentration of S was measured in soil, surface water (soil solution) and leached water. The results showed that the addition of S increased the available S. In general, concentration of S in soil was high for site 1 and 3. It was possible due to the higher clay content for site 1 and 3 compared to site 2. The higher S concentration in soil solution was obtained by treatment T3 for all sites. Sulfur concentration in leached water was higher for T2 compared to T4. It indicated that rice straw could protect the release of S in leached water.
本研究的目的是测定水稻土中硫的释放。试验在温室内进行，土壤样品取自三个不同的地点。处理包括(T0)对照，(T1) 0.02 g S pot-1， (T2) 0.04 g S pot-1， (T3) 0.08 g S pot-1， (T4) 0.04 g S pot-1 +稻草。测定了土壤、地表水(土壤溶液)和浸出水中S的浓度。结果表明，施S使有效硫增加，总体上，站点1和站点3土壤中S浓度较高。这可能是因为1号和3号地点的粘土含量比2号地点高。各试验点土壤溶液中S浓度均以T3处理最高。T2的浸出水中硫浓度高于T4。说明稻草对浸出水中S的释放有一定的保护作用。
