补充资料：土壤改良剂
分子式：
CAS号：
性质：又称土壤调理剂(soil conditioner)。凡主要用于改良土壤的物理、化学和生物性质，使其更适宜于植物生长，而不是主要提供植物养分的物料，都称为土壤改良剂。例如施石灰用来调整酸性土壤的pH值，施石膏用来抑制土壤中的Na+，HCO3-、和CO32-等离子，施用有益微生物来提高土壤生物活性等。但由于改良土壤结构的物料量大面广，所以习惯上人们把土壤结构改良剂与土壤改良剂等同起来。土壤改良剂有多类：(1)矿物类，主要有泥炭、褐煤、风化煤、石灰、石膏、蛭石、膨润土、沸石、珍珠岩和海泡石等；(2)天然和半合成水溶性高分子类，主要有多糖类物料、纤维素物料、木质素物料和树脂胶物质；(3)人工合成高分子化合物，主要有聚丙烯酸类、醋酸乙烯马来酸类和聚乙烯醇类；(4)农作物秸杆类；(5)有益微生物制剂类等。
