| Abstract: |
| The modern test methods such as SEM, permeability coefficient method, pressure-board method, etc, have been adopted to observe and analyze the surface microscopic structure of high polymer absorbent resin and high polymer sand-fixing vegetation compound materials (for short, compound materials), and to compare their influence on the properties of water percolation, conservation and use efficiency of sandy soil. It is proved that high polymer sand-fixing vegetation compound materials are better than high polymer absorbent resin in improving sandy soil, resulting in beneficial gas-liquid-solid ratio of sandy soil for plant growth, and maintaining high water use efficiency. The study results may provide new basis for the application of high polymer sand-fixing vegetation compound materials. |
