doi:10.11924/j.issn.1000-6850.2013-1419

Abstract

Abstract: γ-polyglutamic acid is a new type of biological degradable water-soluble polymer, and its unique structure and physical and chemical properties make it have a broad prospect of application in agriculture. In this paper, γ-polyglutamic acid is briefly introduced from its physical and chemical character and synthesis conditions, and so on, and it is summarized on the application aspects of super absorbent polymers, fertilizer synergia agent and fertilizer relievers in detail. At the same time, it is prospected for the future research, in order to strengthen the application of γ-polyglutamic acid in agriculture and meet saving, high efficiency, safety, low carbon and ecological agriculture and high values.
