微生物对龙葵的生理活性和吸收重金属的影响
Effects of Microorganism on Physiological Activity of Solanum nigrum and Absorption of Heavy Metals
摘要
Abstract
Effects of Paecilomyces lilacinus and Hypocrea virens screened from soil in a landfill on physiological activity of Solanum nigrum and absorption of heavy metals were studied by pot experiment in greenhouse. The results showed that the strains could promote the growth of Solanum nigrum, and thus increase its absorption ability for Cd and Pb. Paecilomyces lilacinus could improve antioxidant capacity of Solanum nigrum, and promoted the migration of Cd from soil to the stem and leaf of Solanum nigrum when soil was only polluted by Cd. While Hypocrea virens could decrease antioxidant capacity of Solanum nigrum, and not promote the migration of Pb when soil was only polluted by Pb. The mixed solution of the two fungus could increase the absorption of heavy metals by Solanum nigrum when soil was polluted by Cd and Pb. The enrichment factor of Cd could reach to 4.25, while that of Pb could only reach to 0.19.关键词
