不同海拔揭膜时间对烤烟产值及品质的影响

摘要

地膜在烤烟生长过程中具有重要的作用及意义，为了探讨地膜最佳揭膜时间，特进行不同海拔揭膜时间对烤烟产值及品质的影响试验，结果表明：在海拔800 m、揭膜时间30 d、在海拔1200 m、揭膜时间为45 d时，烟叶的产量、产值以及烟叶综合指标为最优。%The film plays an important role and significance in the process of flue-cured tobacco growth ,in order to explore the best time of open the film,study on effect of different altitudes and different time of open the film on yield and quality of of flue-cured tobacco was carried out.The results showed that an altitude of 800 m ,open the film 30 days after transplanting and at an altitude of 800 m ,open the film 45 days after transplanting ,the yield ,the yield value and comprehensⅣe index of flue-cured tobacco were optimal.
