移栽期对烤烟新品种金海一号产质量的影响

Effects of Transplanting Time on Yield and Quality of Flue-cured Tobacco New Tariety Jinhai No. 1

通过分期移栽法研究了移栽期对烤烟新品种金海一号烟株生长、烟叶产量和质量的影响。结果表明,在四个移栽期中,中间的两个移栽期T2和T3的产量、产值、均价和上中等烟率都是最高的,而最早的移栽期T1和最晚的移栽期T4的产量、产值、均价和上中等烟率都较低。T1、T2移栽期的烟叶烟碱、总氮、还原糖含量适中,钾含量较高,糖碱比、氮碱比、钾氯比都在合适范围,化学成分协调性分值都在90分以上,都为协调;T3移栽期的还原糖含量偏高,化学成分协调性分值也在90分以上;T4移栽期的烟碱含量偏低,还原糖含量偏高,化学成分协调性分值只有77.71分,表现为基本协调。为实现既提高烟叶的产量、产值、均价等经济效益,又提高烟叶上中等烟率、化学成分协调性和内在品质的目标,金海一号必须适期移栽,移栽期太早和太晚都不利于烟叶产量的形成和品质的提升。

The effects of transplanting time on plant growth,yield and quality of flue-cured tobacco new variety Jinhai No.1 were studied by transplanting on different date.The results showed that in the aspects of yield,production value,average price and first-and-medium-class leaves rate,the best performance appeared in the T2 and T3 transplanting treatments,whose transplanting date were in the middle of the total four trnsplanting treatments.The yield,production value,average price and first-and-medium-class leaves rate of the T1 and T4 transplanting treatments,whose transplanting date were the first and the last in the total four transplanting treatments,respectively,all had poor performance.The contents of nicotine,nitrogen and reducing sugar and the ratios between sugar and nicotine,nitrogen and nicotine,potassium and chlorine of T1 and T2 transplanting treatments were all moderate,and the chemical coordination evaluation values of T1 and T2 were all more than 90 points.The contents of reducing sugar of T3 trnsplanting treatment was on the high side,and the chemical coordination evaluation value of T3 was more than 90 points.The nicotine content of T4 was on the low side,and its reducing sugar content was on the high side,and its chemical coordination evaluation value was only 77.71 points.So in order to both increase production and improve the quality of tobacco leaf,Jinhai No.1 should be transplanted at the right time,not too early and not too late.
