| 摘 要： | 粉煤灰是燃煤电厂排出的固体废弃物,主要成分有SiO2,Al2O3,Fe2O3,CaO等。采用盆栽试验将粉煤灰分别与粘土、砂土、秸秆按3:1的比例混合作为基质种植黑麦草,并用纯粉煤灰基质做对照,研究黑麦草在粉煤灰不同配比基质上的生长状况,结果表明,粉煤灰+粘土为黑麦草的最佳生长基质。

| Abstract: | Fly ash is a kind of solid waste which is composed of SiO2,Al2O3 and Fe2O3 emitted from coal-fired power plant. Pot experiment was done to plant Perennial ryegrass in which fly ash was mixed respectively with clay soil,sandy soil and straw in proportion of 3:1,with pure fly ash in contrast. Vegetal circs that Perennial ryegrass had grown in mixture ratio of fly ash matrix were studied. Results indicated that the best matrix for Perennial ryegrass growth was fly ash mixed with clay soil. |
