沸石是一种含碱金属或碱土金属的硅铝酸盐类矿物。其通用化学结构式可用下式表示:(Na·K)_X(Mg·Ca·Sr·Ba)_Y(A(x+2ysin-(x+2y)O_2n)·mH_2o。由于沸石具有较高的阳离子代换量和较高的持水能力,国外有用沸石矿粉作为土壤结构改良剂。我省经地质部门勘察,在昌潍、烟台二地区蕴藏有大量的沸石,为了探讨沸石对土壤的有关作用,在莱阳县科技办公室的大力支持和协助下,进行本试验。
Zeolites are aluminosilicate minerals containing alkali or alkaline earth metals. The general chemical structural formula can be expressed by the following formula: (Na · K) _X (Mg · Ca · Sr · Ba) _Y (A (x +2ysin- (x +2y) O_2n) · mH_2o. Since zeolite has a higher cationic generation Exchange capacity and high water holding capacity, foreign useful zeolite slag as a soil structure improver.Our province through the geological department survey, in Changwei, Yantai two areas contain a large number of zeolite, in order to explore the zeolite on soil-related role in Laiyang County Science and Technology Office of the strong support and assistance, the test.
