本试验采用室内土柱模拟分析方法,研究了土柱在连续灌溉条件下相同脱硫石膏用量与不同腐植酸用量对盐碱土的改良效果。结果表明,腐植酸施用量越多淋溶液中NaCl和全盐量越少,而Na~+和CaSO_4越多;改良后各处理土壤中NaCl完全
In this experiment, indoor soil column simulation analysis method was used to study the effect of the same gypsum and different amount of humic acid on saline-alkali soil under continuous irrigation conditions. The results showed that the more the amount of humic acid applied, the less NaCl and total salt in the solution and the more Na ~ + and CaSO_4.
