淀粉基可生物降解地膜在烤烟生产中的应用

Research of the Application of Starch-based Biodegradable Film on Flue-cured Tobacco

[目的]研究淀粉基可生物降解膜对烤烟产量、质量及保水效果的影响。[方法]采用田间试验方法。土壤水分测定采用国际GB7172-87方法,取C3F烟叶测定品质状况。[结果]参试淀粉基可生物降解膜在田间可维持膜功效35～45d;与常规膜比较,对烟叶产量和产值没有影响;但是田间降解速度过快且保水性略差于常规膜,对烟叶品质有一定影响。[结论]淀粉基可生物降解膜C型需要进一步优化调整配比,以减缓膜体降解速度。

[Objective]The aim was to research the effection of starch-based biodegradable film against yield,quality and water-effect of tobacco.[Method]Field test method was used.Soil moisture was determined by international GB7172-87 method,C3F tobacco leaves was taked to determined the quality status.[Result]The results showed that the starch-based biodegradable film could maintained the film efficacy for 35-45 days.Compare with conventional film,it had no affect to the output and value of tobacco;While the over-speed degratation and lower waterproof capability had some impact to flue-cured tobacco＇quality.[Conclusion]Starch-based biodegradable film C needed to further optimize the ratio to slow down the degradation rate of membrane body.
