摘要
综述了新型化学抗旱节水材料?高吸水树脂的种类、吸水原理、主要的性能特征以及具体的使用方法。高吸水树脂可以通过抑制水分蒸发,增加土壤含水量以及改良土壤结构等方面,起到保水和促进作物生长发育以及提高产量的作用。指出了我国应在开发研制高吸水树脂保水剂的种类,提高释水性能和降低价格等方面加强研究。
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.
