| 摘 要： | 为了节约淡水资源，合理开发利用微咸水代替淡水来改良盐碱地土壤，本研究采用野外小区试验的方法，对不同灌水条件下滨海盐土土壤的脱盐效果进行分析。结果表明，在良好的排水条件下，采用矿化度约3.5 g/L的微咸水淋洗滨海盐土，能使土壤迅速脱盐，脱盐效果明显。综合节水和脱盐效果双重考虑，微咸水淋洗重壤质滨海盐土，以淋洗量1200 m3/hm2，连续淋洗3次为适宜的淋洗方式，能使0~60 cm土壤剖面的全盐量降低到3 g/kg以下，脱盐率达60%以上，土壤盐分含量达到一般绿化植物的生长要求。

| Abstract: | In order to save fresh water resource,it was necessary to explore and utilize reasonably brackish water replacing fresh water to improve saline soils,the author investigated the desalination effect of heavily-textured coastal saline soils leached by brackish water in field plot experiment.The results showed that in the well drained soils,using the brackish water with salinity of 3.5 g/L could lead to a fast and mark desalination effect.Taking saving water and desalination effect into account,the author sugg... |
