| 摘 要： | 对矸石山的风化物施用化肥或生活污泥，进行种植苏丹草、红豆草的盆栽试验。试验结果：生活污泥对生物量的提高可达极显著水平，当施用６０ｔ／ｈｍ２污泥种植苏丹草时，比只施磷钾肥干物质量增加３３２％；当施用３０ｔ／ｈｍ２污泥种植红豆草，比不施肥增加１５１９％。

| Abstract: | The plantation test of potted beefsteak plant and red bea plant is carried out through application of fertilizers or living sludge to weathered waste rocks. The test results that,the biomass can be remarkably improved through application of living sludge. Dry mass can be increased by 332% through application of 60t/hm 2 sludge for plantation of beefsteak plant than through application of only phosphate and potash fertilizers; and dry mass can be increased by 1519% through application of 30t/hm 2 sludge for plantation of red bea plant than application of no fertilizers. |
