Reinforcement restoration method using hyperaccumulation restoration plant for restoration of cadmium contaminated soil

The invention relates to a method for phytoremediation of cadmium contaminated soil, in particular relates to a reinforcement restoration method using a hyperaccumulation restoration plant for restoration of the cadmium contaminated soil. The hyperaccumulation restoration plant is sowed in ridge tillage and row planting manner in the cadmium contaminated soil in spring, the sowing dosage is 1.8-2.2 grams of seeds in every square metre, the row spacing is 48 to 52 meters, after seedling emergence, when the cadmium hyperaccumulation restoration plant height is about 20cm, levo reduced form glutathione is applied, the applying dose is 0.1-1.0mmol / kg soil, and the applying concentration per kg soil is measured by using the weight of the soil with the soil layer thickness of 0-20 cm of the soil layer surface of the contaminated soil.
