用模拟的方法研究了高吸水性树脂 KH841单施和与 NH_4HCO_3,NH_4Cl,NH_4NO_3,(NH_4)_2SO_4,CO(NH_2)_2,KH_2PO_4,KNO_3,KCl 等肥料分别混施在砂土、砂壤土及含盐壤土上,对土壤水分蒸发和团聚度的影响。结果表明:树脂单施或与肥料混施时,3种土壤的水分蒸发量均与对照没有差异。在砂土、含盐壤土上混施时土壤团聚度与树脂用量呈线性正相关;尿素、NH_4HCO_3与树脂混施对树脂单施时增加土壤团聚度作用的影响较小,而其他电解质肥料与树脂混施则有一定不良影响。
The effects of single application of superabsorbent resin KH841 and fertilizers such as NH_4HCO_3, NH_4Cl, NH_4NO_3, (NH_4) _2SO_4, CO (NH_2) _2, KH_2PO_4, KNO_3 and KCl on sandy soil, Effects of Soil Water Evaporation and Reunion on Salt - Loam Soil. The results showed that there was no difference in water evaporation of the three kinds of soil with the control when the resin was applied alone or mixed with the fertilizer. The results showed that there was a linear correlation between the soil aggregates and the amount of resin when mixed with sand and salty loam soil. The effect of urea and NH_4HCO_3 mixed with resin on soil aggregates was little affected by the single application of resin, while the other electrolyte fertilizers and resin Mixed facilities have some negative effects.
