Through pot experiments, the influence of Cu ²⁺ in soil on the growth status of common economic crops, soybeans, and the remediation effect of soybeans on Cu ²⁺ were studied. The results indicated that with the increase of Cu ²⁺ concentration in the soil, soybeans at different periods (7 days and 21 days) all showed significant changes of reduced biomass and decreased plant height. Soybeans showed better adaptation and tolerance to soil with a Cu 2+ content of 100 mg/kg to 500 mg/kg without wilting or death in the course of growth; With an increase in the concentration of Cu 2+ in soil comes a gradual increase in the uptake Cu 2+ by soy. When the concentration of Cu ²⁺ was 400 mg/kg, the uptake of soybeans reached the threshold within 21 days, with a uptake amount of 113.9 mg/kg, showing a trend of promoting at low concentrations and inhibiting at high concentrations. When the concentration of Cu ²⁺ was 100 mg/kg, the uptake amount of soybeans reached its maximum within 7 days, and the uptake amount was 69.4 mg/kg. This result can further promote the development of research on soybean remediation of Cu 2+ contaminated soil, and provide theoretical and practical support for solving the problem of copper-pollution in farmland.
