摘　　要：采用盆栽试验,研究了施用控释复合肥对烤烟叶片生理特性和氮、磷、钾含量的影响。结果表明:增加控释复合肥的用量能显著提高烤烟叶片生育期的叶绿素、类胡萝卜素(团棵-打顶期)、抗坏血酸(ASA)含量(旺长-成熟期)、超氧化物歧化酶(SOD)活性(团棵-打顶期)和过氧化物酶(POD)活性(旺长-成熟期),同时,烤烟叶片氮、磷、钾含量也呈现上升趋势;相反,增施控释复合肥显著降低了烤烟叶片类胡萝卜素(成熟期)、丙二醛(MDA)、抗坏血酸(团棵期)、谷胱甘肽(GSH)含量(团棵-旺长期)和超氧阴离子自由基(O2·-)产生速率;增施控释复合肥不仅能提高烤烟的抗氧化能力,还能促进对氮、磷、钾营养元素的积累。A pot experiment was conducted to study the effects of applying controlled-release compound fertilizer on the flue-cured tobacco leaf physiological properties and nitrogen,phosphorus and potassium contents.Increasing the application rate of controlled-release compound fertilizer largely improved the tobacco leaf chlorophyll content in whole growth period,the carotenoids content and superoxide dismutase activity at spherical plant-topping stag,and the asorbic acid content and peroxidase activity at fast growing-mature stage.In the meantime,the leaf nitrogen,phosphorus and potassium contents also showed an increasing trend.On the contrary,increasing the application rate of controlled-release compound fertilizer markedly decreased the leaf carotenoids content at mature stage,the malondialdehyde and ascorbic acid contents at spherical plant stage,the glutathione content at spherical plant-fast growing stage,and the production rate of superoxide anion free radicals（O 2·-）.To increase the application rate of controlled-release compound fertilizer could not only improve the antioxidant ability of flue-cured tobacco,but also promote the accumulation of nitrogen,phosphorus,and potassium in leaf.
