对我国水溶肥的应用现状进行了研究。分析了水溶肥应用过程中产生的结垢、腐蚀及土壤问题及对水肥一体化的影响，并对聚天冬氨酸在增强化学肥料的螯合分散性、减缓肥料对管路的腐蚀、增产提质及其环保特性等方面进行了系统的分析，认为聚天冬氨酸在水溶肥的应用方面机遇与问题共存。指出了聚天冬氨酸在水溶肥中可能的应用方向。

The application status of water soluble fertilizer in China was studied in this paper. The scaling， corrosion， soil problems in the application of water soluble fertilizer and its influence on the integration of water and fertilizer were analyzed. The effects of Polyaspartic acid had been also systematically analyzed in the aspects of enhancing the chelation and dispersion of chemical fertilizers， reducing the corrosion of fertilizers to pipelines， increasing production and improving quality， and its environmental protection characteristics. It is considered that the application of Polyaspartic acid in water-soluble fertilizer has both opportunities and problems. At the end of the article， the author points out the possible application direction of Polyaspartic acid in water-soluble fertilizer.
