摘要
我国面临严峻的水资源短缺状况,聚丙烯酰胺(PAM)作为一种高分子聚合物,在农业生产中具有改良土壤结构,提高土壤保水、保土、保肥、保温能力,具有一定的增产功能。针对聚丙烯酰胺在农业生产中的应用,介绍了其特性、作用机理、涉及的因素、存在问题及应用前景。聚丙烯酰胺的施用效果随土壤类型、施用方法、施用量的不同而异,在具体的应用过程中应注意结合实际情况,才能充分发挥其优势。国内外大量研究表明聚丙烯酰胺应用于农业生产,具有显著的经济价值,应用推广前景广阔。
China is facing severe water shortage.As a high molecular polymer,PAM could improve soil structure,increase soil and water conservation,fertilizer and heat preservation ability,and also improve crop yields in agriculture production.Aiming at the application of PAM in agriculture production,this paper mainly introduced the characteristics,mechanism,involved factors,problems and prospects of PAM.The application effects of PAM varied primarily with soil types,application methods and application amounts.In order to give full play to PAM superiority,PAM should be applied according to the actual situation in the specific application process.The domestic and overseas researches indicated that the application of PAM to agriculture production had remarkable economic value and broad prospects.
