以简易垃圾填埋场的垃圾土为研究对象，通过5种草坪植物盆栽试验，研究了添加生物质焦、磷灰石等改良剂对草坪植物生长及抗逆性的影响。结果表明，垃圾土处理能明显增加细叶结缕草、假俭草和大叶油草叶片的相对电导率和 MDA、脯氨酸的含量，从而加剧植物质膜透性和膜脂过氧化程度，进而明显降低叶绿素含量、净光合速率、根系活力以及硝酸还原酶活性，最终减少植物生物量的积累。由生物质焦和磷灰石组成的土壤改良剂对于缓解垃圾土对细叶结缕草和假俭草叶片质膜伤害、提高植物的抗逆性、改善植物的生长活性有着较明显的作用。垃圾土生长环境并未对蔓花生和三裂叶蟛蜞菊造成逆境胁迫，垃圾土和土壤改良剂处理能促进蔓花生和三裂叶蟛蜞菊的生长。研究结果可为简易垃圾填埋场的土地回用、环境修复以及观赏草坪绿地的建设规划提供技术依据。

The effects of the soil remediators composed of bio-char and apatite on the growth and the physiological character-istics of lawn plants grown in landfill soil from a simple dumping-type waste landfill were investigated. The results showed that relative conductivity, the contents of MDA and free proline of Zoysia tenuifolia, Eremochloa ophiuroides and Axonopus affonis were significantly increased under landfill soil treatment. The chlorophyll contents, net photosynthetic rate (Pn), root activity and nitrate reductase acticity were decreased. The biomass accumulation was reduced. Soil remediators alleviated the membrane lipid peroxidation of Zoysia tenuifolia, Eremochloa ophiuroides induced from landfill soil, therefore improved the stress resistance and growth activity of lawn plants. Landfill soil treatment did not caused the stress environment to Arachis duranensis and Wedelia trilobata. Instead, landfill soil environment had the stimulative effects on the growth, similar to the behavior of soil remediators. The results could provide technical basis for land recycling, environment remediation and grass-land construction and planning.
