摘要
为探究三门峡地区适宜的耕作方式,在大田条件下,研究了不同耕作方式对烤烟病害、品质和产量的影响。结果表明,深翻60 cm处理烟株黑胫病发病率低于其他处理;深耕40 cm和深翻60 cm处理烟叶外观质量差异不大,优于旋耕20 cm处理;烤后烟叶的叶面密度、含梗率、填充值、单叶重随土壤翻耕深度增加而降低;烤后烟叶的总糖、还原糖、烟碱、总氮及氯含量随土壤翻耕深度增加而降低,钾含量随土壤翻耕深度增加而升高;烤烟的产量和产值均随土壤翻耕深度增加而提高。
In order to explore suitable tillage methods in Sanmenxia area,the effects of different tillage methods on the disease,quality and yield of flue-cured tobacco were studied under field conditions.The results showed that the incidence rate of black shank was lower in the tobacco treated by deep plowing of 60 cm than that in other treatments.There was little difference in appearance quality between deep tillage of 40 cm and deep plowing of 60 cm,but their effects were superior to rotary tillage of 20 cm.The leaf density,stem content,filling value and single leaf weight of fluecured tobacco decreased with the increase of plowing depth.The contents of total sugar,reducing sugar,nicotine,total nitrogen and chlorine decreased with the increase of plowing depth,the potassium content increased with the increase of plowing depth.The yield and output value of flue-cured tobacco increased with the increase of plowing depth.
