【摘要】：為了研究不同改良劑對(duì)濱海鹽堿土壤的改良效果,采用有機(jī)改良劑、沸石和園林廢棄物3種改良劑的組合,通過5種不同的配比處理對(duì)河北省黃驊市中捷友誼農(nóng)場(chǎng)的濱海鹽堿土進(jìn)行改良,通過田間試驗(yàn),改良1年后取樣,測(cè)定8大離子含量及土壤總鹽分,探討3種改良劑的對(duì)濱海鹽堿土的改良效果。結(jié)果表明:5種處理均能顯著降低濱海鹽堿地的總鹽分含量,與對(duì)照相比,T4、T5、T1、T2、T3分別降低了65.03%、47.48%、47.34%、45.24%、41.78%;T4處理下土壤總鹽分含量顯著低于其他4種處理;5種處理均能顯著降低Na+含量,與對(duì)照相比,T4、T5、T3、T2、T1分別降低了69.55%、65.43%、62.96%、57.61%、54.73%;5種處理均能顯著降低Cl~-含量,與對(duì)照相比,T4、T5、T1、T3、T2分別降低了76.35%、64.97%、61.49%、55.84%、50.17%;T4處理還能夠顯著降低K~+、Ca~(2+)、Mg~(2+)和SO_4~(2-)含量,與對(duì)照相比,分別降低了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，
