摘要
[目的]研究轮作和连作对美引品种NC102和NC297烟叶品质的影响，为其优质烟叶的生产提供理论依据。[方法]研究轮作和3年连作对NC102和NC297品种种植区域的土壤理化性状、养分及烟叶化学成分、感官质量和经济效益的影响。[结果] NC102和NC297品种连作3年后，土壤中碱解氮、速效磷、速效钾和有机质含量均下降；土壤酸化现象明显；与3年连作田相比，轮作田种植的NC102和NC297品种烟叶主要化学成分协调性更好，感官评吸质量及经济效益更优。[结论]轮作是提高NC102和NC297品种烟叶品质、保证烟农利益的重要耕作制度。
Abstract
Objective] To research the effects of rotation and continuous cropping on the leaf quality of tobacco varieties NC 102 and NC297 introduced from USA, and to provides theoretical basis for the production of tobacco varieties leaves .[ Method] Effects of rotation and three-year continuous cropping on the soil physical and chemical properties , nutrient,chemical components in tobacco leaves were researched , as well as the sensory quality and economic benefit of NC102 and NC297in planting area. [Result] After continous croping of NC102 and NC297 for three years, available nitrogen, rapidly-available phosphorus, rapidly available potassium and organic matter contents in soil all reduced. Compared with three-year continuous cropping, the main chemical copmponents of NC102 and NC297 in rotation plough land had better coor-dination, sensory smoking quality, and economic benefit.[ Conclusion] Rotation is an important farming system to enhance the tobacco leaf quality of NC297, and to ensure the interest of tobacco farmers.
