摘要: 针对河套地区氯化物型盐碱土的特点,通过室内土壤改良试验,研究了201×4强碱性苯乙烯系阴离子交换树脂与3种酸性材料(腐殖酸、泥炭、磷酸一铵)配施对盐碱土盐碱离子的吸附钝化效果。结果表明:在201×4树脂施用量为2%时,其与泥炭10:15比例配施改良效果较为哭出,较对照土壤水溶性Na^+合量下降了21.41%,水溶性cl合量下降了34.36%,水溶性SO4^2-合量下降了87.88%,全盐合量下降了30.64%,较单施201×4树脂土壤pH值下降了0.78,可以作为今后盐碱土改良剂配万材料。

Abstract: According to the characteristics of chloride saline-alkali soil in Hotao area,the effects of 201×4 strongly basic styrene anion exchange resin mix with three kinds of acidic materials (humic acid, peat, mono-ammonium phosphate) on the passivation effect of salt and alkali was studied through indoor soil improvement experiment in this paper. The results show that application effect is outstanding when the 201×4 resin application rate is 2%, and mix with peat in 1 : 1.5 ratio. Compared with the CK, the content of water-soluble Na^+ in soil decreased by 21.41%, the content of water-soluble Cl- decreased by 34.36%, the content of water-soluble SO4^2- decreased by 87.88% and the content of total soluble salt in soil decreased by 30.64%. The soil pH decreased by 0.78 compared with the single application of 201×4 resin. They could be used as the materials to improve saline-alkali soil in the future.
