土壤的盐从哪来的？造成土壤盐现象的原因有以下几点为因素不合理的施肥方式：过量施用化学肥料；偏施肥料，只施用氮肥，不施有机质和中微量元素肥料；期不补充有益微生物菌。劣质粪肥施用：如掺入火碱的鸡粪，会破坏土壤酸碱度，对

1、有些盐碱地属于原生盐碱地，即本来该地的土壤中就含有较多盐分，例如远古湖泊退化形成的沼泽、海滨盐碱地等。这些地区的盐分来源跟当地情况有关，包括成土母质、海水倒灌、地下水含盐量大等等；但是有一点相同，就是基本上跟类影响无关，故称原生盐碱地。2、还有一种次生盐碱地，即主要由于类不合理灌排度导致的土壤盐碱化，典型的例子就是古代两河文明的消。土地盐碱化是指土壤中盐分过高，而影响植物正常生的一种现象。其成因主要有以下几个方面：首先，降水不足导致土壤中水分蒸发过多，盐分浓度增加。其
