摘要
为探明立体育苗及井窑式移栽促进烟草生长的机理,通过大田试验分析了4种栽培方式对白肋烟农艺性状、叶片活性氧代谢、激素含量、经济产量及化学品质的影响。结果表明,立体育苗结合井窑式移栽的组合栽培方式取得最显著改善效果。在农艺性状方面,可以显著提高株高、茎围、腰叶面积及叶数;在生理指标方面,团棵期CAT、SOD活性及IAA含量比对照分别提高了53.7%、35.1%、17.2%,MDA含量降低29.3%,成熟期CAT、POD的活性提高幅度分别为38.7%、28.2%,MDA及ABA含量降低幅度分别为35.3%、31.0%;调制后烟叶产量和产值分别提高了30.0%和39.1%,中上等烟率提高了13.3%,并通过改善烟叶总植物碱含量、氮碱比、钾氯比等指标提高了烟叶化学成分协调性。
In order to find out the mechanism of promoting tobacco growth by the application of stereoscopic seedling nursing andwell-cellar transplanting, we studied the effects of four different cultivating patterns on agronomic traits, active oxygen metabolism,hormone concentration, economic yield and chemical quality of burley tobacco. The experimental results showed that stereoscopicseedling nursing combined with well-cellar transplanting showed the most obvious advantages. On the agronomic traits, the newpattern significantly improved plant height, stem diameter, the maximum leaf area and leaf number during the all growing stages. Onthe physiological traits, the activities of CAT and SOD increased by 53.7% and 17.2%, respectively, and the IAA concentrationincreased by 17.2% and MDA concentration decreased by 29.3% at the rosette stage. At the mature stage, the activities of CAT andPOD increased by 38.7% and 28.2%, respectively. The concentration of MDA and ABA decreased by 35.3% and 31.0%, respectively.On the yield and chemical quality traits of tobacco leaves, the new pattern’s yield, output value rate of and medium-superior tobaccoincreased by 30.0%, 39.1% and 13.3%, respectively, and the content of total alkaloids, the ratio of total nitrogen to total alkaloids, theratio of total potassium to total chlorine were also significantly improved.
