【摘要】 本论文在旨在解决保水剂在实际应用中的筛选种类、使用方法和最佳施用浓度，并对土壤保水剂的应用效果进行评价。 通过对比试验，测定不同类型土壤保水剂保水性和持效性的差异，分析研究影响土壤保水剂保水性能的主要影响因子。 在大量室外试验数据的基础上，通过施用土壤保水剂和对照试验，研究保水剂的使用浓度、处理方式对土壤水分、土壤理化性质、林木生长的影响。 最后，论文对土壤保水剂应用的适宜水分条件、使用方法、浓度配比做了系统介绍，希望能在该研究方面进行有益尝试，全面了解认识土壤保水剂的特性，更加广泛的推广土壤保水剂的应用。更多还原

【Abstract】 The Study on characteristics of super absorbent polymer (SAP) aims at solving the problems that how to select it, how to use it and what is the optimal quantity. The application effect was evaluated as well.By comparison, this study determined the durative characteristic and water preservation of different sorts of SAP . also analysised The factors that have notable effects on water preservation capability of SAP were also analyzed.Based on a great deal of field experiments, The effect of SAP on the properties of soil water, the physical and chemical characteristics of soil, and the growth of trees was also analyzed through disposal methods, different using dose, and mixture dose.Finally, The feasible water condition, using methods, mixture dose of SAP was introduced systemically to have a try on realizing the property of SAP roundly and spreading its application widely.更多还原
