Porous laminated silicate as desert tackling material

The present invention reveals one kind of porous laminated silicate as desert as desert tackling material. It is prepared with completely weathered laminated silicate and salt fertilizer solution and through intercalation replacing reaction. It has 16-18 times raised water absorbing capacity, 6 times raised fertilizer fixing capacity and powerful wind erosion resistance. It has integrated fertilizer fixing , water fixing, sand fixing and soil improving functions and is one kind of green desert tackling material without secondary pollution. 本发明披露了一种多孔状层状硅酸盐治沙新材料。系利用完全无机土质化的层状硅酸盐特殊的层状结构，以盐肥柱撑专用液与其进行插层置换反应，得到的以盐肥离子柱撑为特征的多孔状层状硅酸盐，其吸水能力提高16～18倍，固肥能力提高6倍，在沙中添加3.5％即可抗12米/秒大风风蚀30分钟，它集固水、固肥和沙化土地结构改良于一身，且还不会造成二次污染，是一种卓有成效的绿色环保治沙新材料。
