双行凹型垄覆膜栽培技术对高海拔地区烤烟产质量的影响

目的]探索双行凹型垄覆膜栽培技术对高海拔地区烤烟(Nicotiana glauca L.)产量和质量的影响。方法]以云烟87为研究对象,随机区组设计,研究不同覆膜栽培方式对烤烟农艺性状、重要化学指标、产量及经济指标等的影响。结果]全生育期覆膜处理对烤烟各性状的影响效果比团棵期揭膜好,双行凹型垄覆膜比单行垄覆膜好。结论]该研究可为地膜覆盖在烟草上的合理应用提供理论依据。

Effects of Double Rows on Concave Ridges with Plastic Film Mulching Cultivation Technique on Yield and Quality of Flue-cured Tobacco(Nicotiana glauca L.) in High Altitude Regions

Objective] To explore the effects of double rows on concave ridges with plastic film mulching cultivation technique on yields and quality of flue-cured tobacco in high altitude regions.Method] Yunyan 87 was selected as the research object,through randomized block design,to seek the differences of flue-cured tobacco agronomic traits,important chemical indexes,yields and economic indicators caused by different film mulching styles.Result] The results showed that film mulching in the whole growth period was better than opening film in rosette period,double rows on concave ridges with plastic film mulching was superior to one ridge film mulching.Conclusion] The study provides a theoretical basis for reasonably applying film mulching in tobacco production.
