摘要
文章从环境建设的可持续发展出发 ,结合天津开发区在基础设施及园林绿化建设中面临土源紧缺的现实 ,将周边地区大量存在的海湾泥、粉煤灰、碱渣土等废弃物配制成一种新型种植基质以代替农田客土 ,并对其理化性质和对植物的适宜性进行了详细的试验研究。实验及推广结果表明海湾泥与碱渣土或粉煤灰按 3∶1比例混合最适宜 ,同时该配比基质在土壤改良和植物适宜性方面均优于滨海盐土 。
Baed on the study on the physical and chemical characteristics, three solid wastes, namely ooze, alkaline slag, coal ash, that have been piled up largely in coastal region are converted into a kind of artificial soil and substituted for the foreign soil. It relieves the shortage of planting soil of the landscaping construction in TEDA and also accords with the sustainable development demands for the environmental construction. Experiments and applications show that the most feasible mixing proportion of ooze to alkaline slagor coal ash is 3∶1. Further more, the artificial soil exceeds coastal solonchak in amelioration of soil and plant suitability. Its overall benefit is prominent. [
