| 摘要 |
Disclosed is a method of forming a superabsorbent polymer product and a product formed by entrapping a bioactive, growth-promoting additive in a starch matrix to form a starch-based superabsorbent polymer (SAP) product for use in agricultural applications, wherein the method involves (1) graft polymerizing a monomer and a starch to form a starch graft copolymer including a starch matrix; (2) isolating the starch graft copolymer; (3) forming particles of starch graft copolymer; and (4) adding a bioactive, growth-promoting additive such that at least some of the bioactive, growth-promoting additive is entrapped by the starch matrix. By placing the starch-based SAP including a bioactive, growth-promoting additive in proximity to a plant, root, seed, or seedling, the growth of the plant, root, seed, or seedling is promoted because availability of beneficial nutrients is increased. |
