| Abstract: |
| Poly-γ-glutamic acid (γ-PGA) as a new environment-friendly polymeric biomaterial,due to its own good water absorption,slow-release properties,and its degradation products are non-toxic and edible,it has been widely used in cosmetics, food,medicine and other fields.In the field of agricultural soil and water as water retention agent and fertilizer synergistic agent.Studies in recent years have confirmed that γ-PGA also shows great potential and broad application prospects in the agricultural field.In this paper,the application of γ-PGA in agricultural soil and water engineering is taken as the starting point,emphatically summarized and analyzed effects of γ-PGA on soil physiochemical,biological characteristics and water and fertilizer protection;and evaluated the effects of γ-PGA on crop growth and development,nutrient absorption and physiological characteristics.Based on the systematic analysis and evaluation of the application of γ-PGA in farmland system, putting forward the existing research challenges,prospecting the problems that need to be further studied,which laid a foundation for further research and application of γ-PGA in the field of agricultural engineering. |
