土壤连续灌溉对上部鲜烟叶素质及烤后外观质量的影响
Effects of Applying Continuous Irrigation on Tobacco Cultivated Soil on Fresh Leaf Quality and Appearance Quality of Upper Leaves of Flue-cured Tobacco
摘要
Abstract
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 ofupper 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.关键词
