Abstract: Field experiments were conducted to evaluate the application effect of biodegradable plastic film on flue-cured tobacco production of Qujing tobacco-growing areas with PE plastic film. The results showed that, the effect of biodegradable plastic film on soil moisture retention and temperature preservation was slightly worse than that of PE film, which had adverse effects on soil main nutrients and soil pH value. The black biodegradable plastic film broke 15 days earlier than the white one, and the degradation rate reached 63.73% after 150 days,while the degradation rate of the white biodegradable film reached 55.41%. The white biodegradable plastic film was beneficial to improve the coordination of chemical components in upper and middle tobacco leaves. The bio-degradable plastic film has better degradation performance, which is helpful to improve the coordination of chemical components of tobacco leaves, but the effect of heat preservation and moisture preservation is not good. The effect of white biodegradable plastic film is better than that of black biodegradable plastic film.

Key words: fully biodegradable plastic film, flue-cured tobacco, chemical composition coordination
