摘要
为生物降解地膜在永州烟区烤烟生产中推广应用提供理论依据,采用单因素试验研究不同生物降解地膜在烤烟生产上的适用性。结果表明:生物降解地膜各处理的土壤保温保湿效果、烤烟的农艺性状和产质量与普通地膜处理无明显差异;生物降解地膜处理较普通地膜处理节约用工成本587.88元/hm2,易降解,田块残留物较少,生态环保效果较好。以60d开始降解的生物降解地膜处理的纯收益最高,比普通地膜处理增加2 564.08元/hm2,且经济性状优于其余生物降解地膜处理。湖南永州植烟区烤烟地膜覆盖栽培宜选用60d开始降解的生物降解地膜。
The applicability of different biodegradable mulch films in flue-cured tobacco production was studied by a single-factor test to provide the theoretical basis for popularization and application of biodegradable mulch film in flue-cured tobacco production in Yongzhou tobacco growing area.Result：There are no obvious differences in keeping soil temperature and humidity,and agronomic traits,yield and quality of flue-cured tobacco between biodegradable mulch film treatment and common mulch film treatment but the biodegradable treatment can save 587.88 Yuan/hm^2（labor cost）and is easily degraded compared with common mulch film and has a good effect of ecological environment protection.Net income of the biodegradable mulch film treatment with beginning to degrade in 60 dis the highest,2 564.08 Yuan/hm^2 higher than common mulch film treatment.The economic traits of flue-cured tobacco applied with the biodegradable mulch film treatment with beginning to degrade in 60 dis better than the biodegradable mulch films treatment with beginning to degrade in 90 dand 120 d.In conclusion,the biodegradable mulch film with beginning to degrade in 60 dshould be used in plastic film treatment mulching cultivation of flue-cured tobacco in Yongzhou tobacco growing area,Hunan.
