摘要
针对当前生态环境建设及节水农业发展所产生的技术需求 ,对保水剂的应用历史、结构组成、作用机理、使用方法及效果等进行了较为系统的分析 ,并探讨了保水剂农用研究存在的问题。表明保水剂可望成为旱作生产技术体系中的重要组成部分 ,但由于其功能的发挥受多种因素的制约 ,其应用成效的取得 。
Aimed at technical requirements rising from eco environmental construction and water saving agricultural development at present, comprehensive analysis was made to history for application of water holding agent to agriculture, its structure, composition, acting mechanism, applying method and effect, and also approach to the existing problems in research into water holding agent. It was shown that water holding agent would be hopeful to become one of important technique components in rain fed production , but further systematic researches would be needed for getting fine applying effect because its function is restricted by many factors.\;
