通过蔬菜施肥情况调查、土壤养分的化验、土壤障碍因子的成因分析,得出大量施用高浓度复合肥是造成蔬菜土壤磷钾富营养化、酸化、次生盐渍化等现象的主要原因之一,并提出实施测土配方施肥,推广施用蔬菜专用肥、水旱轮作、灌水洗盐等改良措施。 Through the investigation of fertilization of vegetables, the analysis of soil nutrients and the analysis of the causes of soil disturbance factors, it is concluded that the application of high concentration of compound fertilizer in large quantities is one of the main causes of phosphorus and potassium eutrophication, acidification and secondary salinization in vegetable soil , And proposed the implementation of soil testing and fertilizer, promote the use of special fertilizer for vegetables, irrigation and drought rotation, irrigation salt washing and other improvements.
