摘　　要：结合南方稻田烟区实际,以云烟97品种为材料,研究了上部叶成熟期间植烟土壤保持连续灌溉对不同成熟度鲜烟叶素质及烤后外观质量的影响。结果表明,烟田经连续灌溉处理后,上部鲜烟叶干重显著降低,叶长及鲜重随成熟度增加而下降的程度减小,叶绿素含量在进入成熟中后期后明显下降。烤后外观质量、均价和上等烟比例均优于自然排灌处理的上部烟叶,成熟度及发育状况得到改善,叶面疏松度明显提高,油分增多,色度变浓,色均匀度有所增加。According to the practice of paddy filed tobacco-planting area at southward of China,the flue-cured tobacco variety Yunyan97 was used as test material to detect the effects of keeping tobacco cultivated soil irrigated continuously at maturing stage of upper leaves on fresh leaf quality and cured tobacco leaves appearance quality about different harvest maturity.The results showed that,after applying the treatment of continuous irrigation on tobacco fields,the dry weight reduced remarkably,the decreasing amplitude of leaf length and fresh weight became small with the increase of harvest maturity,and the chlorophyll content decreased significantly when upper leaves went into the medium-latter stage of maturation process.The appearance quality,average price,and high class leaf proportion of upper leaves after flue-curing were superior to those without special irrigation treatment.The maturity,development,and openness of upper leaves were all improved.And the oil,saturation,and color uniformity of upper leaves increased as well.
