摘要
腐殖酸是一种具有多种官能团,能够与土壤中微量元素络合,增强土壤团粒结构,促进植物根系生长发育,提高作物对营养元素的吸收,改良土壤好氧细菌活性的有机化合物质。课题通过试验研究,探索腐殖酸在改良受土霉素污染的土壤方面的生物学作用,模拟自然环境下土霉素对土壤环境的污染,土壤中各类活性酶的状况,如脲酶、磷酸酶、过氧化氢酶等的生物活性,深入挖掘腐殖酸在土壤修复及农业生产中的重要作用,为农业生产及区域经济发展提供理论支撑。
Humic acid is an organic compound with multiple functional groups,which can complex with trace elements in soil,enhance soil aggregate structure,promote plant root growth and development,improve the absorption of nutrients by crops,and improve the activity of soil aerobic bacteria.This experiment was conducted to explore the biological role of humic acid in improvement of the soil polluted by oxytetracycline,to simulate the pollution of oxytetracycline to the soil environment in the natural environment,the status of various active enzymes in the soil,such as the biological activities of urease,phosphatase and catalase,and deeply excavate the important role of humic acid in soil remediation and agricultural production.This study provides a theoretical support for agricultural production and regional economic development.
