【Abstract】 Adoption of drought - resistance and water-conservation polymer is a new developed non-structural water-saving measure in recent years. In prac-tice, the water-conservation capacity of polymer is impacted greatly by many factors, such as soil, fertilizer and water. The qualitative research on water-conservation characters of the polymer is conducted under different applied conditions. Some problems and suggestions on application of water-conservation polymer are provided by authors.更多还原
