摘要
通过盆栽试验的方法研究富钙水淋洗与改良剂结合对滨海盐土的改良效果,结果表明:富钙水淋洗能明显降低土壤含盐量,提高土壤的入渗能力。富钙水淋洗与改良剂配合提高土壤入渗能力的效果更为明显,并抑制淋洗后土壤pH的升高,对改善土壤结构、培肥土壤和降低土壤碱性有良好的效果。
The effect of soil amendment and calcium nitrate solution leaching was studied.Results showed that calcium nitrate leaching alone significantly reduced soil salt content and improved soil infiltration capacity.A combination of soil amendment and calcium nitrate leaching greatly improved soil infiltration,inhibited the increase of soil pH,improved soil structure,fertilized soil,and decreased soil alkaline.
