摘要
由于其超高吸水和保水性,高吸水性树脂已被广泛应用于各种领域,并且在无土栽培中显示出了越来越广阔的发展前景。笔者首先回顾了高吸水性树脂的超高吸水性、保水性和保肥性;其次简述了高吸水性树脂的吸水机理;然后从栽培基质的角度总结了高吸水性树脂与其他栽培基质混合使用作为保水保肥剂以及其单独作为栽培基质——水晶泥在无土栽培中的应用状况;最后为促进高吸水性树脂在无土栽培中的大范围推广应用,笔者提出了今后的几个主要发展方向。
Because of their ultra-high water-absorption and water-retention,super absorbent polymers have been widely used in various fields and will show more and broader prospects in soilless cultivation.This article firstly reviewed the high water-absorption,water-retention and fertility preserving capability of super absorbent polymers.Secondly briefed their water absorbing mechanism,then from the angle of culture media summarized their application conditions in soilless cultivation,included that they were used with other culture medium as water and fertilizer retention agent and lonely used as a kind of culture media-crystal mud.Finally the author offered several major developing directions to promote their application on a large scale in soilless cultivation.
