摘　　要：三年小区试验和大面积示范表明，发展畜牧、增施有机肥，可使土壤有机质和土壤全氮增加。水稻优化施肥，薯、麦配方施肥，调整氮、磷、钾比例，改变当地氮素投入大于产出、磷素基本平衡、钾素亏损较大的局面，并能提高氮素利用率，增加产量，节省肥本。合理使用植物营养素，可使甘薯、小麦、水稻、花生、大豆诸作物增产。The plot experiments and large-area demonstration in three years indicated that the practices of developing animal husbandry and applying organic manure could increase the organic matter and to-tal nitrogen in the soil.The optimum fertilization for rice and formula fertilization for sweet potato and wheat and adjusting the proportion of N,P,K changed the situation of nitrogen,which was over-ap-plied for crop production,and that of potasium was deficient fo a great extent,thus raised N- utilizing efficiency,increased yield and saved fertilizer cost.The optimum utilization of plant nutrient elements enabled the increase of crop yields of wheat,rice,peanut and soybean.
