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
