Abstract

The invention discloses a plant repair method of applying a transgenetic plant composite system to polluted soil. A transgenetic plant is obtained by steps of construction of a plant transformation vector, plant genetic transformation and the like. The transgenetic plant can be used for plant repair of heavy metal polluted soil and water bodies. The transgenetic plant shows a hyperaccumulating characteristic and resistance to different heavy metals such as lead and cadmium, can be widely applied to repairing heavy metal polluted soil, and has efficient repair efficiency to the polluted soil. The plant repair method can be used to polluted soil caused by mining, soil pollution of surrounding earth piles, and polluted soil of a waste site of an electroplate factory and the periphery, for example, various composite metal polluted soil such as Cd, Cr, Cu, Pb, Z and Ni. The plant repair method has the multiple advantages of being high in adaptability, environmentally friendly and the like in repair of composite polluted soil, and has a wide application prospect.

Description

technical field

[0001] The invention relates to the fields of biotechnology and soil restoration, in particular to a method for specific expression of exogenous genes in restoration plants and a heavy metal restoration technology applied to polluted soil. Background technique

[0002] Soil is the natural environment on which human beings depend and an important resource for agricultural production. Various food, resource and environmental problems faced by the world are closely related to soil. Since the last century, the continuous development of mining and metallurgy, and the widespread use of various chemical products, pesticides and fertilizers have led to the emergence of heavy metal soil and groundwater pollution. Soil heavy metal pollution refers to the phenomenon that human activities bring heavy metals into the soil, resulting in changes in soil composition and physical and chemical properties, resulting in degradation of soil quality and ecological deterioration. ...
