【摘要】 为研究福建省不同海拔区域不同移栽期和打顶方式对‘翠碧一号’烟叶品质的影响,采用田间随机区组试验对烟叶生长和品质进行研究。结果表明,在250 m海拔区域,随着移栽期和打顶期推迟,烟株生育期缩短、株高增加、发病率上升、产质量下降、化学成分协调性和感官质量下降;在650 m海拔区域,随着移栽期和打顶期推迟,烟株生育期缩短,农艺性状变化不显著,发病率变化不明显,产值量、化学成分协调性和感官质量呈先上升后下降的趋势。为了提高烟叶品质和产量,在福建省250 m海拔区域,‘翠碧一号’应提前移栽(1月10日)、初花打顶(10%中心花开发);而在福建省650 m海拔区域,‘翠碧一号’应中期移栽(2月4日)、盛花打顶(40%中心花开发)。更多还原

【Abstract】 To study the effect of different transplanting time and topping modes on the quality of‘CB-1’tobacco leaf in different altitude areas of Fujian Province, field randomized block tests were conducted. The results showed that in 250 meters altitude area, with the delay of transplanting time and multi-topping period,the growth duration of tobacco was shortened, the plant height was increased, the incidence rate went up, the yield and quality of flue-cured tobacco was deteriorated, and the coordination of chemical components and the sensory quality was decreased. In 650 meters altitude area, with the delay of transplanting time and multitopping period, the growth duration of tobacco was shortened, no significant changes in agronomic traits were observed, the incidence rate had no obvious change, the yield and quality of flue-cured tobacco, and the coordination of chemical components and the sensory quality were first increased and then decreased. To improve the yield and quality of flue-cured tobacco, in 250 meters altitude area of Fujian Province, the planting of‘CB-1’should be carried out by earlier transplanting(January 10) and initial flowering topping(10% central flower development). In the 650 meters altitude area of Fujian Province,‘CB-1’should be cultivated by mid-term transplanting(February 4) and full flowering topping(40% central flower development).更多还原
