【摘要】：为了研究不同改良剂对滨海盐碱土壤的改良效果,采用有机改良剂、沸石和园林废弃物3种改良剂的组合,通过5种不同的配比处理对河北省黄骅市中捷友谊农场的滨海盐碱土进行改良,通过田间试验,改良1年后取样,测定8大离子含量及土壤总盐分,探讨3种改良剂的对滨海盐碱土的改良效果。结果表明:5种处理均能显著降低滨海盐碱地的总盐分含量,与对照相比,T4、T5、T1、T2、T3分别降低了65.03%、47.48%、47.34%、45.24%、41.78%;T4处理下土壤总盐分含量显著低于其他4种处理;5种处理均能显著降低Na+含量,与对照相比,T4、T5、T3、T2、T1分别降低了69.55%、65.43%、62.96%、57.61%、54.73%;5种处理均能显著降低Cl~-含量,与对照相比,T4、T5、T1、T3、T2分别降低了76.35%、64.97%、61.49%、55.84%、50.17%;T4处理还能够显著降低K~+、Ca~(2+)、Mg~(2+)和SO_4~(2-)含量,与对照相比,分别降低了93.33%、76.09%、68.75%、55.01%。
[Abstract]:In order to study the improvement effect of different modifiers on littoral saline-alkali soil, the combination of organic modifier, zeolite and garden waste was used. The seashore saline-alkali soil of Zhongjie Friendship Farm in Huanghua City Hebei Province was improved through five different proportion treatments. The soil salt content and total salt content of 8 major ions were determined by field experiment after one year's improvement. The improvement effect of three kinds of modifiers on coastal saline-alkali soil was discussed. The results showed that the total salt content in littoral saline-alkali soil was significantly decreased by five treatments, and the total salt content of soil was significantly lower than that of the other four treatments (P < 0.05), and the total salt content of soil was significantly lower than that of the other four treatments (P < 0.01), compared with that of the control, and the total salt content of the soil was significantly lower than that of the other four treatments (P < 0.05). The total salt content of the soil was significantly lower than that of the other four treatments (P < 0.01), and the total salt content of the soil was significantly lower than that of the other four treatments (P < 0.05). 涓庡鐓х浉姣，
