烟草的生长发育受到多种因素的影响,为探究移栽期对烟叶产量和品质的影响及寻找江西抚州烟区烟草的最佳栽植期,本研究对不同移栽期的烟叶大小、产质量及化学品质进行检测。结果表明,随着烤烟移栽期的推迟,叶片逐渐变宽,下部叶尤为明显;烟叶的产量逐渐增加,上等烟的比例是先上升后下降;均价和单位面积产值都以T3期的最高;烟叶的总糖含量、钾含量随移栽期推迟逐渐增大,总氮含量、烟碱含量逐渐减小;烟叶的糖碱比、氮碱比等化学成分也以T3期的最协调。比T3期(3月9日移栽)提前或推迟10 d(T1期或T5期)移栽对生产优质烟叶有不利影响。抚州地区3月14日移栽(T3期)较为适宜。
Tobacco growth and development by a variety of factors, in order to explore the effects of transplanting on the yield and quality of tobacco leaves and find the best planting period of tobacco in Fuzhou tobacco-growing areas in Jiangxi Province, this study on the different transplanting of tobacco leaf size, quality and Chemical quality testing. The results showed that with the delay of transplanting of tobacco leaves, the leaves became wider and the lower leaves became more obvious. The yield of tobacco increased gradually and the proportion of top tobacco increased first and then decreased. The average price and output per unit area were calculated as T3 The content of total sugar and potassium in tobacco increased gradually with the delay of transplanting, the content of total nitrogen and nicotine gradually decreased; the chemical components of tobacco leaf such as ratio of sugar to base and ratio of nitrogen to base were most coordinated with T3. Transplanting earlier or later than 10 days (T1 or T5) than T3 (March 9 transplanting) had an adverse effect on producing high quality tobacco leaves. Fuzhou area on March 14 transplanting (T3 period) is more appropriate.
