摘要
通过室内模拟试验,利用正交回归设计研究了丙烯酸盐类保水剂对土壤持水性能的影响,并推导出土壤有效水含量与土壤质地、保水剂粒径及其使用剂量关系的数学模型。结果表明:土壤质地、保水剂用量对土壤有效水含量的影响达到极显著水平,而保水剂粒径对土壤有效水含量的影响不显著。保水剂颗粒与土壤质地、与保水剂用量成负效应,保水剂用量与土壤质地成正效应。这一数学模型可以用于指导该类保水剂在生产的使用。
<Abstrcat> The effect of acrylic acid super absorbent ploymer on the soil water content using regression-orthogonal design experiment at indoor laboratory was studied. The mathematics model for the relationships among soil available water content with soil texture, particle diameter and dosage of super absorbent ploymer(SAP) was deduced. The result shows that the effect of soil texture and dosage on soil available water content is significant, but the effect of particle diameter of water-holding reagent(SAP) on soil available water is not significant. Therefore, this type of super absorbent ploymer can be used rationally in production based on the mathematics model.
