摘　　要：定位试验结果表明,猪厩肥的土壤培肥功能最显著;秸秆对增强土壤供钾能力和改善土壤物理性状具有积极作用,当其与猪厩肥配合施用时培肥效果更突出;化肥对提高作物产量的贡献较大,而对保持提高土壤肥力的作用较小.A fixed trial showed that pig manure was best for enriching soil fertility among all measures used. The application of stalks had also a positive effect on the availability of soil K, and the improvement fo soil physical properties as well. However, chemical fertilizers could contribute to crop yield considerably, rather than improving soil fertility.
