井窖移栽配以三角栽培技术对白肋烟生长发育及产质量的影响

为研究不同栽培模式在烟草种植上的应用效果,通过田间试验比较了井窖移栽配以三角栽培技术对白肋烟农艺性状、光合速率、内源激素含量、化学品质以及经济产量的影响。结果表明：①井窖式移栽和三角栽培增加了白肋烟的株高、叶面积和单株叶片数,提高了大田生长期的光合速率;②井窖式移栽和三角栽培提高了白肋烟各生育期间叶片中IAA含量,并且降低了旺长期和成熟期JA与ABA的含量;③井窖式移栽和三角栽培降低了烟叶中烟碱的含量,提高了钾含量及中部叶糖含量,增加了经济产量;④在其他条件相同情况下,移栽方式是影响产量和产值的主要因素,贡献率分别为78.57%和61.96%,栽培方式是影响上中等烟率、烟碱和钾含量的主要因素,贡献率分别为68.62%、62.10%和54.74%,移栽与栽培方式对上中等烟率和钾含量存在显著互作效应,贡献率分别为6.95%和45.21%。

Effects of Well-Cellar Transplanting with Triangulation on Growth,Development,Yield and Quality of Burley Tobacco

The effects of well-cellar transplanting with triangulation on agronomic traits, photosynthetic rate, endogenous hormone concentration, chemical quality and economic yield of burley tobacco were compared through field experiments. The results showed that well-cellar transplanting with triangulation increased tobacco height, leaf area, effective leaf number and the photosynthetic rate in the growing period in the field experiment. The IAA concentration during the growth period were increased compared with CK, and the JA and ABA concentration was reduced at fast-growing and mature stage. Different cultivation models reduced the nicotine content in tobacco leaves, and increased the potassium and sugar content and the economic yield. Under the same situation, the analysis of interaction effect showed that transplanting method was the main factor influencing the yield and output value, and the contribution rate were 78.57% and 61.96%, respectively. Cultivation method was the main factor influencing the medium-superior tobacco rate, nicotine and potassium content, and the contribution rate were 68.62%, 62.10% and 54.74%, respectively. Transplanting and cultivation methods on medium-superior tobacco rate and potassium content had significant interaction effect and the contribution rate were 6.95% and 45.21%, respectively.
