摘要:

为研究不同腐殖酸配施钙、镁的土壤调理剂在淋洗条件下对盐碱土的改良效果,采用回填土柱淋溶系统并设置腐殖酸原粉及硝基腐殖酸与钙、镁配施6个处理,通过9次淋洗,对土壤淋出液及土壤中pH、电导率、矿化离子的变化情况进行了试验研究。试验结果表明:硝基腐殖酸+磷石膏(质量比3 :1配施,666.67 m2施用量375 kg)处理在淋洗过程中可有效降低土壤中Na+和Cl-的含量,且相对于其他处理的土壤pH维持在较低水平,其为淋洗方式下改良土壤盐碱性较佳的土壤调理剂。

Abstract:

In order to study the improvement effects of different humic acid soil conditioners containing calcium and magnesium under leaching condition, the backfill soil column leaching system is adopted and 6 treatments of original humic acid powder and nitro-humic acid with calcium, magnesium are designed, through leaching for 9 times, experimental study on the changes of pH, electric conductivity and inorganic ions in soil leaching solution and soil is carried out. Experimental results show that the treatment of nitro-humic acid + phosphogypsum (mass ratio 3 :1, application amount 375 kg per 666.67 m2) can decrease the Na+ and Cl- content in soil effectively during leaching process, and compared to other treatments, the soil pH value maintains at low level, so it is a better soil conditioner for improvement of saline alkali soil under leaching condition.
