| Abstract: | Super absorbent polymer (SAP) is a kind of new chemical drought-resistant and water-absorbent materials. Their categories and water-absorbent principles were summarized. Their main properties and applying methods were described as well. The functions of SAPs were brief reviewed, such as the ability of improving soil structure and water retention, inhibiting water evaporation, promoting crop growth and output. It was pointed out that those research aspects must be strengthened, including developing new types of SAPs, enhancing water-releasing capacity,cutting down the price and so on. |
