摘要:
以3种单质肥料和3种复合肥料及5种规格保水剂为试材，研究不同浓度的肥料溶液对不同粒径的保水剂性能所产生的影响。结果表明：保水剂在肥料溶液中的吸水倍率随着肥料浓度的增加而减小；同一种保水剂，小颗粒的吸水倍率要比大颗粒的吸水倍率大，6种肥料中磷酸二氢钙对保水剂吸水倍率的影响最大。不同种类的保水剂具有不同的分子结构、离子种类以及亲水基团等，这就决定了不同种类的保水剂对水的吸收能力各有不同。
Abstract:
Taking 3 kinds of fertilizers and 3 kinds of compound fertilizer and 5 kinds of specifications of water retaining agent water performance as test materials，the influence of different concentrations of the fertilizer solution generated for different grain sizes of SAP absorbing performance were studied.The results showed that the water absorbency，water retaining agent in the fertilizer solution decreased with increasing of the fertilizer concentration；with the same kind of water retention agent，water absorbency of small particles was bigger than the water absorbency of large particles，in 6 kinds of fertilizer,water absorbency reached the maximum of calcium phosphate.Different water retaining agent with different structures,ion type and hydrophilic group,which determines different water retaining agent with different abilities.
