摘要
通过对吉林省晒红烟糖分积累规律及不同施肥水平对糖分影响的试验,探究提高晒红烟内在品质的氮、磷、钾最佳配比组合,结果表明,叶片的还原糖、总糖从移栽后30 d开始迅速增加,根、茎部是从移栽后40 d开始迅速增加,超过50%的还原糖、总糖都是在成熟期积累;还原糖、总糖日积累出现最高值在移栽后60,70 d,叶片分布最多,茎次之,根最少.综合分析延晒5号在100 kg/hm2施氮水平上的氮、磷、钾配比组合最佳.
To inquisition the best combination of N,P205 ,K2 of the Sun-cured Tobacco import the inherent quality, studied the effect of accumulation rule of the Sun-cured Red Tobacco and the ratio of different fertilization of sugar in Jilin. The results showed that reducing sugar and total sugar was accumulated rapidly since 30 days after transplanting in leaf, and since 40 days after transplanting in root and stem. More than 50 % of reducing sugar and total sugar were started to accumulate since maturity. The peaks of daily accumulations of reducing sugar and total sugar were appeared at sixtieth day and seventh after transplanting, respectively. Sugar in tobacco leaves is the highest, stem times, roots for at least. It is to say variety Yanshai No. 5 is the best at the combination of N,P2O5 ,K2 which the nitrogen level is 100 kg/hm^2.
