Abstract: Superabsorbent resin as a new kind of functional polymer material has been extensively used in agriculture. In this paper, the mechanism of high water-absorbency, characteristics, categories and methods for uses of the polymer in agricultural application is introduced. The mechanism of soil improvement, drought relief and water saving, growth promoting as well as affecting factors on such functions are analyzed. The topics for research and future trend are discussed.
