| 摘 要： | 通过盆栽试验的方法研究微咸水淋洗与施改良剂结合对滨海盐土的改良效果,结果表明:微咸水淋洗能够明显降低土壤全盐量和Na+、Cl-含量,但会造成土壤pH值的升高;改良剂葡萄酒泥和脱硫石膏配合施用能够降低土壤pH值,增加土壤养分含量;微咸水淋洗与施改良剂结合对黑麦草的出苗和生长都有一定的促进作用。

| Abstract: | A pot experiment was to investigate the effects of the combined application of brackish water leaching and soil amendments on coastal saline soils. The results showed that brackish water leaching could significantly reduce soil total salt content, Na^＋, Cl^- and enhance soil pH. The combined application of wine precipitate and desulfurized gypsum could decrease soil pH and increase soil nutrients. Soil amendments combined with brackish water leaching improved the seedling emergence and growth of ryegrass. |
