采用室内模拟研究结果表明，在还原作用下锰的淋溶呈现先增后降，而且起落较大；铁的淋溶呈逐渐增加的趋势；碱金属与碱土金属的淋溶特点是初时淋溶量很大，以后不断地降低；铝的淋溶量较小，硅的淋溶量较大，尤其在盐基淋失到一定程度后，渗透液中硅铝含量在缓慢地增加本文还讨论了母质类型及土壤有机质类型对元素淋溶的影响．“双层母质”不是白浆士形成的必要条件。
The results of laboratory simulation show that the leaching of manganese increases firstly and then decreases with the increase of the fall, and the rising of the leaching is larger. The leaching of iron shows a gradual increase trend. The leaching characteristics of alkali metals and alkaline earth metals are the initial leaching Large, and then continue to decrease; leaching of aluminum smaller, larger leaching of silicon, especially in the salt leaching to a certain extent, the silicon and aluminum content in the permeate is slowly increasing This article also discusses the parent material Effect of Type and Soil Organic Matter on Elemental Leaching. “Double parent material” is not a necessary condition for the formation of white pulp.
