| 摘要: |
| 用模拟的方法研究了高吸水性树脂 KH841单施和与 NH4HCO3,NH4Cl,NH4NO3,(NH4)2SO4,CO(NH2)2,KH2PO4,KNO3,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。 |

| Abstract: |
| With the simulated test,the effects on soil water evaporation and aggregation are studied when high water absorbing synthetic resin KH841 is applied to sandy soil,sandy loam soil and salinized loam soil singly or with fertilizer such as NH_4HCO_3,NH_4Cl,NH_4NO_3,(NH_4)_2SO_4,CO(NH_2)_2,KH_2PO_4, KNO_3,KCl.The results indicated that the soil water evaporations by applying fertilizer have no difference from the control;when the resin is used singly or with NH_4HCO_3,the relationship between the aggregation va... |
