| Abstract: | 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. |
