摘要

为探讨生物炭作为土壤隔盐层的作用效果，通过对比生物炭隔盐层和常规的砾石隔盐层室内淋洗的暗管流速、淋滤液电导率、土壤脱盐率及淋洗效率等指标，对生物炭作为隔盐层的作用效果进行了评价。结果表明：生物炭处理的暗管流速明显高于砾石处理，平均高出16.1%；淋滤液电导率0.83mS/cm为本研究的理论淋洗终点，2个处理均在第2次淋洗过程中到达理论淋洗终点，且生物炭处理比砾石处理到达理论淋洗终点时间缩短了13.3%；2个处理的土壤淋洗效率基本相同；生物炭隔盐层在抑制土壤返盐方面的作用要明显优于砾石隔盐层。综上，生物炭作为隔盐层在盐碱土淋洗改良中的作用效果要优于传统的砾石隔盐层，研究结果为生物炭隔盐层在盐碱地改良的工程应用提供了参考依据。

Abstract

To investigate the effects of biochar as a salt-isolation layer in soil

the effect of biochar as a salt-isolation layer was evaluated by comparing the flow rate of subsurface pipe

the conductivity of leachate

the rate of soil desalination

and the efficiency of leaching of the biochar salt-isolation layer to the conventional gravel salt-isolation layer. The results showed that the flow rate of subsurface pipe of the biochar treatment was 16.1% higher than that of the gravel treatment. The leachate conductivity of 0.83 mS/cm could be treated as the theoretical end point of the leaching. Both treatments reached the theoretical end of leaching during the second leaching process

and the time consuming of the biochar treatment reached the theoretical end of leaching was 13.3% shorter than that of the gravel treatment. The soil leaching efficiency of the two treatments were almost the same. The soil resalinization preventing effect of the biochar salt-isolation layer was better than that of the gravel salt-isolation layer. To sum up

the application effects of the biochar salt-isolation layer were better than that of the traditional gravel layer. The research results provided a reference for the engineering application of the biochar salt-isolation layer in saline-alkali land improvement.
