Abstract

The invention provides a method for enhancing the remediation ability of cosmos sulphureus to cadmium pollution soil in an orchard. The method includes the steps of taking two strains of cosmos sulphureus with different sizes, using the larger cosmos sulphureus as a stock, using the smaller cosmos sulphureus as a scion, and grafting. By means of the method, cadmium accumulation in the cosmos sulphureus can be promoted, and the remediation ability of the cosmos sulphureus to the cadmium pollution soil in the orchard can be improved.

Description

technical field [0001] The invention belongs to the technical field of agriculture and soil restoration, and in particular relates to a method for enhancing the restoration ability of chrysanthemum chrysanthemum to cadmium-contaminated soil in orchards. Background technique [0002] With the development of cities, the pollution of urban heavy metals (especially cadmium) is becoming more and more serious. At present, the common method is to use cadmium hyperaccumulator plants for green restoration, but judging from the screened cadmium hyperaccumulator plants or cadmium enrichment plants, most of them are weed plants, few flower plants, and there are biological low volume limitations. Therefore, while continuing to screen floral cadmium hyperaccumulator plants, it is necessary to improve the selected floral cadmium hyperaccumulator plants, so that they can fully play their role in phytoremediation. [0003] The flower plant Cosmos sulphureus is a cadmium-accumulating plant,...
