| 摘 要： | 采用四因素三水平正交改良方案对盐分含量较高的赤泥基质进行了改良研究和植物种植试验。结果表明:4种改良剂均能降低土壤的pH值,其中磷石膏对赤泥基质的pH影响最大;赤泥基质的持水率则主要受膨润土的影响,膨润土对赤泥基质的盐分具有一定的吸附或交换作用,添加量为20%时,赤泥可溶性盐含量降低了50%;3种供试植物中黑麦草最适宜改良后的赤泥基质种植。

| Abstract: | Orthogonal design experiments of planting Lolium perenne L.,Elymus dahuricus,Sudan grass on the improved high-salts content red mud with acidic waste phosphogypsum,biomass sawdust,bentonite and peat were carried.The results showed that the four adding components could bring down the pH of red mud especially phosphogypsum,water holdup rate of red mud soil was mainly effected by bentonite.Bentonite shows a remarkable ability of retaining the soluble salts.Soluble salts of red mud decreased 50%when bentonite a... |
