| 摘 要： | 本文通过对辽宁省大豆主要产区(8个县)土壤全硫及有效硫含量进行测定与分析,阐述了不同类型、不同肥力土壤硫素状况。在不同地区开展的硫肥肥效试验结果表明,在有效硫含量很低的土壤上施用硫肥增产效果都很明显,而有效硫含量较高的土壤上施用硫铵增产效果较好,石膏和硫磺的增产效果不稳。 |

| Abstract: | The contents of soil total S and available S in the soybean-planted areas (8 counties) in Liaoning Province were determined in order to clarify the status of S nutrition in main soil with different fertility levels. The results obtained from the effectiveness of S fertilizers in different areas showed the yield of soybean increased significantly in the soil with lower available S under the application of S fertilizers. However, only the ammonium sulfate had a good effectiveness in the soil with higher available S. The gypsum and mineral sulfur had no significant effect for increasing the yield of soybean. |
