광산석질변파생태수복기술중보수제적선용시연구적기출화중점。본연구채용고흡수성수지—취병희산갑/납량충SAP진행시험,분석량자흡수배/속솔、보수능력급은정성,설계11충불동배비적기질,연구식물발아솔、존활솔、항한능력급기질보수력。결과표명,재석질변파생태수복기질SAP선택상,선용취병희산갑SAP,병차시용량위2.0%교우。
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.
