为探求碱渣的农用资源化途径 ,对花生、水稻等作物进行了施用碱渣试验。结果表明 ,花生施用碱渣有很好的增产效果 ,水稻施用碱渣效果不理想。在作物营养上 ,施用碱渣后植株的镁含量显著增加 ,磷含量有所下降 ,花生植株氮含量明显上升。施用碱渣对土壤的酸性有良好的改善作用 ,可明显提高土壤的 pH值 ,但土壤的有效磷含量下降 In order to explore the way of agricultural resource utilization of alkali residue, the alkali residue test was carried out on the peanut and rice crops. The results showed that the application of alkali residue in peanut had a good yield increase effect, and the effect of using alkali residue in rice was not satisfactory. In the crop nutrition, the Mg content of the plant significantly increased after application of alkali residue, phosphorus content decreased, nitrogen content of peanut plants increased significantly. The use of caustic soda has a good effect on the acidity of the soil, which can obviously improve the pH of the soil, but the available phosphorus content in the soil is decreased
