不同种植方式和留叶数对烤烟生长及产质量的影响
Effects of Different Planting Methods and Remained Leaf Numbers on Growth,Yield and Quality of Flue-Cured Tobacco
摘要
Abstract
In order to explore the effects of different planting methods and remained leaf numbers on growth,yield and quality of flue-cured tobacco,a two-factor field split-plot experiment was carried out in Jiange County,Guangyuan City,Sichuan Province in 2019.Two planting methods with equal row spacing(A1)and wide-narrow row(A2)were set in the main plot,and three remained leaf numbers were set as 14 to 16(B1),16 to 18(B2)and 18 to 20(B3)per plant in the subplot,which formed 6 treatments(A1B1,A1B2,A1B3,A2B1,A2B2 and A2B3).The effects of different treatments on the agronomic and economic traits of tobacco plants,and the contents of conventional chemical components and sensory smoking quality of flue-cured leaves were studied.The results showed that the plant height of tobacco increased with the increase of remained leaf number after topping under the two planting methods,while the maximum leaf area de-creased,the yield of flue-cured tobacco increased,and the average price,proportion of middle and superior tobacco and output value increased first and then decreased.The output value,average price and proportion of superior tobacco of A2B2 treatment were obviously higher than those of the other treatments.There were differ-ences in the content of conventional chemical components in flue-cured tobacco leaves among different treat-ments.The content and coordination of conventional chemical components in flue-cured tobacco were overall better under A2B2 treatment.The sensory smoking quality of flue-cured tobacco leaves(C3F)increased first and then decreased with the increase of remained leaf number,and reached the highest value when the re-mained leaf number was 16 to 18 per plant.The aroma quality,and smoke and taste of A2B2 treatment were the best.In summary,the treatment of wide-narrow row planting with 16 to 18 remained leaves per plant(A2B2)had the best comprehensive yield and quality,followed by the treatment of equal row spacing com-bined with 16 to 18 remained leaves per plant(A1B2).The conclusion of this study could provide the theoret-ical basis and data support for high-yield and good-quality cultivation of flue-cured tobacco.关键词
