烤烟品种云烟85在三明烟区的栽培特性研究

Study on cultural characters of flue-cured tobacco variety Yunyan85in Sanming

试验研究了不同播种期和不同施肥量对烤烟新品种云烟85的产量、质量的影响,结果表明,云烟85表现出较强的耐肥性和适应性,在福建省三明烟区适宜的施氮量为每公顷112.5～135.0kg,云烟85对低温比较敏感,容易发生早花,在三明烟区的播种期和移栽期不宜太早,云烟85在中期和后期长势旺盛,烟叶产量、上等烟比例和均价都明显高于K326,烟叶的内在化学成分比较协调,不抗花叶病,易感青枯病。

The effects of different fertilizer application level and different seeding time on the yields and quality of YunYan85,a new cultivar of flue-cure tobacco were studied in this paper.The results showed that Yunyan85had stronger tolerance to fertilizer and adaptability.The suitable nitrogen dosage was ranging from112.5to135kg /hm 2 .However,YunYan85is sensitive to microtherm,resulting in early blossom ing eas-ily.The seeding and transplanting time in Sanming should not be too earily.The plants of YunYan85were growing luxuriantly at middle and late developmental stages.Tobacco yield,the ratio of upper class leaf and average price of the cultivar were significantly higher than that of K326.The inherent chemical com-ponents in tobacco leaf of YunYan85were harmonious relatively.YunYan85has no resistance to TMV and granville wilt.
