The invention discloses application of a full-biodegradable film in remediation of heavy metal Cr-polluted soil and growth promotion and quality improvement of flue-cured tobaccos. By applying the full-biodegradable film in the heavy metal Cr-polluted soil, the bioavailability of the heavy metal Cr in the soil can be effectively reduced, the content of Cr in roots, stems and leaves of the flue-cured tobaccos can be reduced, and the quality of the flue-cured tobaccos is improved. The flue-cured tobacco root activity and growth development are promoted. 本发明公开了全生物降解膜在重金属Cr污染土壤修复和烤烟促生提质方面的应用，通过在重金属Cr污染土壤中施入全生物降解膜，不但能有效降低土壤中重金属Cr的生物有效性，而且还能降低烤烟根、茎和叶中Cr含量，促进烤烟根系活性和生长发育。
