摘要
矿山石质边坡生态修复技术中保水剂的选用是研究的基础和重点。本研究采用高吸水性树脂—聚丙烯酸钾/钠两种SAP进行试验,分析两者吸水倍/速率、保水能力及稳定性,设计11种不同配比的基质,研究植物发芽率、存活率、抗旱能力及基质保水力。结果表明,在石质边坡生态修复基质SAP选择上,选用聚丙烯酸钾SAP,并且施用量为2.0%较优。
In mine rocky slope ecological restoration,the selection and using of super absorbent polymers in substrate configuration was the research base and key.Using super absorbent polymer-polyacrylic acid sodium/potassium SAP,the SAP of bibulous rate,and water retention capacity and stability were analyzed,11 different proportion matrix was deviced,and the indexes of plant germination rate,survival rate,drought resistance and each matrix＇s water retention capacity were studied.The results showed that the selection of SAP in rocky slope ecological restoration technology was preferred,choosing polyacrylic acid potassium SAP,with 2.0% application amount.
