全生物降解地膜应用对烤烟产质量的影响

摘要

Objective]The aim was to study effects of full biodegradable film on yield and quality of flue-cured tobacco.[Method]With K326 as test materials, through field experiment, effects of different size, color full biodegradable film on flue-cured tobacco growth period, agro-nomic traits, economic traits, yield and quality were studied.[ Result] The growth period and agronomic traits of flue-cured tobacco had no significant difference among treatments, economic traits were best by covering 1 m(width) ×0.010 mm(length) black full biodegradable film, while tobacco qualities were best by using 1 m(width) ×0.008 mm(length) black full biodegradable film.[Conclusion] The study can pro-vide theoretical basis for popularization and application of full biodegradable film.%[目的]研究全生物降解地膜应用对烤烟产质量的影响。[方法]以K326为试验材料，通过田间试验，研究覆盖不同规格、不同颜色的降解膜对烤烟生育期、农艺性状、经济性状、产质量等的影响。[结果]各处理间烤烟大田生育期和农艺性状差异不大，经济性状以覆盖宽度×厚度为1 m ×0．010 mm的黑色全生物降解膜处理表现较好，烟叶品质以覆盖宽度×厚度为1 m ×0．008 mm的黑色全生物降解膜处理表现最佳。[结论]该研究可为全生物降解地膜的推广应用提供理论依据。
