中文摘要	选用目前农业生产上应用较多的几种可用于地面成膜的高分子材料，模拟田间地表喷施处理，研究测试其在地表使用后对土壤结构有关的主要物理性质的影响。包括高分子材料对表土成膜性和抗破碎性的影响、对干湿土壤粒级分布变化的影响、对土壤团粒结构及土壤团粒水稳性的影响、以及对土壤水入渗性能的影响，分析比较高分子材料与固土有关性能关系。研究建议用SQ值（土壤水稳性结构商）、A％（〉2mm团粒％）、WMWD（湿筛土壤平均重量粒径）可作为衡量干土团聚性能和湿土团聚水稳性能的主要指标，或作为对不同高分子固土材料的改土性能评价重要指标。用SQ值、A％、WMWD对不同高分子材料固土性能综合比较，MPAM（M-聚丙烯酰胺）处理的SQ值、WMWD值和A％值均为最大，表明其对表土成膜性、抗破碎性和团粒水稳性影响均最强，可优先推荐配合在节水灌溉和旱地保护性耕作土壤上应用；EBT（乳化沥青）处理的A％值排序最后，但SQ值和湿筛WMWD排序提前，表明其与土壤的固结力相对较强，可用于护坡固沙抗水蚀；CLF（交联性丙烯酰胺）处理的A％值排序靠前，但SQ值和湿筛WMWD排序最后，说明其与土壤的固结力和对土壤团粒水稳性影响相对较弱，适用于季节性干旱地区土壤保水保肥，尤其可作为经济作物的节水栽培管理措施。该研究为新型高分子材料的农用开发及其生产应用可行性提供依据。[著者文摘]
英文摘要	Some macromolecule materials, widely used for soil surface conditioning in agricultural field at present, were selected to detemiine their effects of simulated surface application on soil aggregate-related physical properties, including on surface film-formation, soil erosion-resistance, changes in dry/wet particle-size distribution, soil aggregation and water-stability, as well as hydraulic conductivity, and to make comparison and evaluation of soil stability associated with the tested materials. The results suggested that the SQ (stability quotient), A% (percentage of dry-sieved aggregates >2 mm) and WMWD (wet-sieved mean-weight diameters) be used as main index to measure soil dry/wet aggregate stability or to evaluate soil stability of macromolecule materials. In comparison of the tested materials, the highest values in SQ, A% and WMWD associated with M-PAM (polyacrylamide) surface treatment showed that MPAM had the strongest effects on film-formation, erosion-resistance, and aggregate water-stability and can be recommended as practices combined with water-saving irrigation and soil conservation tillage in dryland soil. With EBT (emulsified bituminous material) treatment, the least A%, but the higher SQ and WMWD indicated that EBT had stronger aggregate water-stability and can be used on slope and sandy land for protecting soil against water erosion. With CLP (crosslinked polyacrylamide) treatment, the higher A%, but the lower SQ and WMWD suggested that CLP had the weaker wet aggregate water-stability and is suitable for water and fertilizer conservation in seasonal drought soils, and especially is applicable for water-saving cultivation management of cash crops. This study has provided informations for the development of new-type macromolecule materials in agricultural land application.
