It is conducive to uptake soil nitrogen for flue-tobacco on dryland soil with maize-tobacco rotation before topping (60 days after transplanting) and uptake soil nitrogen for flue-tobacco on paddy soil with rice-tobacco rotation after topping.2 The nitrogen utilization efficiency of rapeseed cake, rice straw and rape straw were 19.5%, 15.5%, 8.1% respectively, and the inorganic fertilizer nitrogen utilization efficiency were 41.1%, 42.7% and 35.7% under the combined application of organic additives and inorganic nitrogen fertilizer. The contribution rate of rapeseed cake, rice straw, rape straw to accumulated nitrogen of flue-cured tobacco were 1.0%, 2.4%, 2.7% respectively by the combined application of organic additives and nitrogen fertilizer. Flue-cured tobacco for organic nitrogen absorption meet with the nitrogen needs laws of high-quality tobacco, indicating that the combined application organic additives and inorganic nitrogen fertilizer reduces the nicotine content of tobacco, an increase of sugar/nicotine ratio and improved the quality of tobacco. In which the role of rice and rape straw is greater than the rapeseed cake can be used as measures to lower nicotine.3 Nitrogen accumulation in flue-cured tobacco with the total nitrogen input was a significant positive correlation during the growth stage of flue-cured tobacco. The total nitrogen input for the 156.3-405.5kg.hm-2, in which the soil nitrogen mineralization capacity account for 22.6%-54.3%, with an average of 34.5%, that is, soil nitrogen mineralization accounted for 1/3 of the total nitrogen input.

旱地轮作土壤有利于烤烟生长前期对土壤氮素的吸收，水旱轮作土壤增加了烤烟生长后期对土壤氮的吸收。2在有机添加物与无机氮肥配施条件下，烤烟对有机添加物中氮的吸收规律基本符合优质烟的需氮规律，其中烤烟对菜籽饼肥、稻草秸秆、油菜秸秆所含氮素的利用率分别为19.5%、15.5%、8.1%，所配施无机氮肥的利用率分别为41.1%、42.7%和35.7%，菜籽饼肥、稻草秸秆、油菜秸秆对烤烟氮素累积量的贡献分别为1.0%、2.4%、2.7%。3不同轮作方式及添加有机物条件下氮素平衡结果显示，烤烟生长期间的氮输入总量为156.3-405.5kg.hm-2，其中矿化氮量为输入总氮量的22.6%-54.3%，平均为34.5%，约为输入总氮量的1/3；肥料氮的利用率为31.4%-42.7%；植烟土壤氮素表观损失率在37.5%-57.2%，平均为46.9%，约为输入总氮量的一半。
