摘要: 采用大田试验,以覆盖PE地膜为对照,比较研究了2种生物全降解地膜在曲靖烟区烤烟生产中的应用效果。结果表明,生物全降解地膜土壤保墒保温效果整体较PE地膜稍差,对土壤主要养分及土壤酸碱度有不利的影响;黑色生物全降解地膜较白色生物全降解地膜提前15 d出现破裂,150 d后降解率达63.73%,白色生物全降解地膜降解率达55.41%;白色生物全降解地膜有利于改善中上部烟叶化学成分的协调性。生物全降解地膜具有较好的降解性能,有利于改善烟叶化学成分的协调性,但保温保墒效果稍差,白色生物全降解地膜效果优于黑色生物全降解地膜。

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
