摘要
目前,干旱已成为抑制我国农业的生产发展的重要影响因素,为了解决水资源缺乏带来的农业生产障碍,土壤保水剂应运而生。试验采用水溶液聚合法制备土壤保水剂,结果证实:聚天冬氨酸和膨润土在制备过程中发生了反应形成了具有粗糙的表面和多孔结构新的复合物。对其进行性能测定的结果表明:该土壤保水剂具有较好的吸水性、保水性和热稳定性和一定的可重复使用性。
At present,drought has become an important influencing factor inhibiting the production and development of China s agriculture,in order to solve the agricultural production obstacles caused by the lack of water resources,soil water retainers came into being.The experiment used aqueous solution polymerization method to prepare soil water retaining agent.The results confirmed that polyaspartic acid and bentonite reacted during the preparation process to form a new complex with a rough surface and a porous structure.The results of its performance determination showed that the soil water retention agent had good water absorption,water retention and thermal stability and certain reusability.
