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.
