Effects of Rotation and Continuous Croppin g on the Leaf Quality of Tobacco Varieties NC102 and NC297 Introduced from USA
摘要
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.关键词
