摘要
由于某些不合理耕作栽培措施的持续影响,我国部分地区土壤物理性质逐渐退化。高分子材料因其具有独特的分子结构,内含丰富的活性基团,以及良好的粘结性,在土壤物理性质改良方面具有实质效果,受到了越来越多研究人员的关注。本文通过综合国内外对高分子材料在土壤物理性质改良方面的研究,主要对天然高分子(多聚糖类、腐殖酸类、纤维素类、木质素类)和合成类高分子(阴离子型、阳离子型、非离子型)的类型及其功能进行了详细的分类概括和综述,同时简要阐述了不同高分子改性材料及其与其他改良材料联合作用在改良土壤物理性质、减少水土流失方面的研究现状,并结合当前高分子材料在土壤改良研究中存在的问题,提出了新的看法与展望。
Soil physical properties are gradually deteriorated in some regions because of the long-term inadequate farming practices in China. Polymer materials have increasingly been employed to improve soil physical properties because they have unique molecular structures, abundant functional groups and good adhesiveness. This paper summarized the types and functions of the natural(e.g., polysaccharides, humicacids, cellulose and lignin), and synthetic polymer materials(e.g., anionic, cationic and nonionic polymers), and reviewed the effects of modified polymers, and combination of polymers and other soil amendments on the improvement of soil physical properties and the control of soil erosion. In addition, this paper summarized the problems that existed in the research of amelioration of soil physical properties by using polymer materials, and pointed out the new ideas and prospect research in the future.
