全生物可降解地膜在烤烟生产中的应用

Study on Application of Full Biodegradable Plastic Film in the Flue-Cured Tobacco Production

以普通地膜为对照,在烤烟生产中开展了全生物可降解地膜应用效果试验,旨在为可降解膜的推广应用提供实践经验和理论依据。结果表明,T1、T2两种全生物可降解膜在使用30 d后出现不同程度的开裂,150 d后两种膜的降解率均达到70%以上;可降解膜保苗、保温保湿效果能够达到与普通地膜一致的水平,在不影响烟株正常生长的前提下,能表现出较好的经济性状。可见,全生物可降解地膜具备普通地膜的功能,能够满足烟株生长发育需求,且降解率高,可有效解决田间白色污染问题,具有良好的社会生态效益和市场前景。

In order to provide practical basis and theoretical basis for the popularization and application of biodegradable film,the application of the whole biodegradable membrane in the production of flue-cured tobacco was compared with the ordinary plastic film.The results showed that the full biodegradable plastic film of T1 and T2 happened different degrees of cracking after 30 days,and the degradation rate of the above two kinds of flue-cured tobacco reached more than 70% after150 days; Full biodegradable plastic film and ordinary plastic film can achieve the same level on the keeping a full stand of seedlings,heat preservation and moisture,it can obtain better economic traits under the premise of not affecting the normal growth of tobacco plants.Obvious that the full biodegradable plastic film not only has the function of ordinary film,able to meet the needs of the growth and development of tobacco,and the degradation rate is high,which can effectively solve the white pollution and has good social and ecological benefits and market prospects.
