探究烟稻复种区烤烟氮、磷、钾养分积累，烟叶产量、产值对施氮量和基追肥氮比例的响应，为稻茬烤烟制定施肥策略。以云烟87为材料，设计氮用量水平150、165、180 kg/hm²和基追肥氮比例为3∶7、5∶5，采用效应值（）分析氮用量、基追肥氮比例及其互作对氮、磷、钾养分积累的贡献率。结果表明：烤烟积累的氮、磷、钾养分主要分配给烟叶，且随着烤烟生长，分配给烟叶的比例也减少。随着氮用量的增加，烤烟的氮积累量、烟叶产量、产值也增加；减少基肥氮比例，可显著提高烟株氮积累量和烟叶产量、产值，显著提高氮肥利用率和氮、磷、钾肥的偏生产力、偏生产效益。氮用量、基追肥氮比例及其互作对烤烟氮积累的贡献率平均值分别42.89%、29.63%、27.47%，对磷积累的贡献率平均值分别为38.62%、24.12%、37.25%，对钾积累的贡献率平均值分别为41.22%、21.24%、37.54%，对产量的贡献率平均值分别为62.13%、6.34%、31.53%，产值的贡献率平均值分别为47.30%、14.74%、37.95%。整个生育期，施氮量180 kg/hm²和基追肥氮比例3∶7处理的氮积累量相对较多；在团棵期和圆顶期，施氮量180 kg/hm²和基追肥氮比例3∶7处理的磷、钾积累量相对较多；施氮量180 kg/hm²和基追肥氮比例3∶7处理烤烟产量和产值最高。因此，在烟稻复种区，氮用量对烤烟氮、磷、钾养分积累的影响最大，烤烟生产中基肥氮比例由50%减少至30%，可提高烟叶氮积累量，有利于烟叶产量、产值及氮肥利用率的提高。

The response of nitrogen, phosphorus and potassium nutrient accumulation, yield and output value of flue-cured tobacco in multi-planting area of tobacco-rice to the nitrogen application and basal-topdressing ratio was studied to provide a theoretical basis for the development of fertilizer application strategies for paddy-tobacco. Cultivar Yunyan 87 was used and three nitrogen application treatments (150 kg/hm², 165 kg/hm² and 180 kg/hm²) and two basal-topdressing ratio of nitrogen treatments (3∶7 and 5∶5) were set up. The effects of nitrogen application and basal-topdressing ratio on the accumulation and distribution of nitrogen, phosphorus and potassium nutrients, also on yield, output value and fertilizer utilization of paddy-tobacco, and the contribution rate of nitrogen application and basal-topdressing ratio and the interaction to the accumulation of nitrogen, phosphorus and potassium were analysed using the effect value (). The results showed that nitrogen, phosphorus and potassium nutrients accumulated by flue-cured tobacco were mainly allocated to tobacco leaves, and the proportion allocated to tobacco leaves decreased with the growth of flue-cured tobacco. With the increase of nitrogen application, nitrogen accumulation and tobacco yield and output value of flue-cured tobacco increased, meanwhile reducing the proportion of base fertilizer nitrogen could significantly increase the nitrogen accumulation of the tobacco plant and yield and output value of tobacco leaf, also significantly increase the utilization rate of nitrogen fertilizer and the partial productivity and the partial production benefit of nitrogen, phosphorus and potassium fertilizers. On average, nitrogen application and basal-topdressing ratio and the interactions contributed 42.89%, 29.63% and 27.47% to nitrogen accumulation of flue-cured tobacco, and 38.62%, 24.12% and 37.25% to phosphorus accumulation, and 41.22%, 21.24% and 37.54% to potassium accumulation, and 62.13%, 6.34% and 31.53% to yield, and 47.30%, 14.74% and 37.95% to output. Throughout the reproductive period, nitrogen accumulation was relatively high in the nitrogen treatments of 180 kg/hm² and the 3∶7 basal-topdressing N ratio. In the rosette stage and dome stage, the accumulation of phosphorus and potassium was relatively high in the nitrogen treatments of 180 kg/hm² and 3∶7 basal-topdressing N ratio. The highest yield and output value were achieved in the nitrogen treatments of 180 kg/hm² and 3∶7 basal-topdressing N ratio. Therefore, in the multi-planting area of tobacco-rice, the nitrogen application has the greatest influence on the accumulation of nitrogen, phosphorus and potassium nutrients in flue-cured tobacco, and the reduction of the proportion of base fertilizer nitrogen from 50% to 30% can increase the accumulation of nitrogen of tobacco leaf, which is conducive to the improvement of the yield and output value of tobacco leaf and the utilization rate of nitrogen fertilizer.

湖南烟稻复种区的烤烟大田前期雨水多^[1]，肥料流失严重^[2]，其施氮量一般在180 kg/hm²，远高于云南和河南烟区^[3-4]，不仅增加了烤烟生产成本，还污染烟区生态环境，减少烤烟生产的氮肥施用量迫在眉睫。改进施氮方式，采用合理的基追肥氮比例，使烟田供肥强度与烟株需肥强度一致^[2-3]，使烟株充分吸收养分，能有效减少肥料流失，从而提高烟叶产量和品质。在多雨的南方烟区，采用地膜覆盖^[5]、减少基肥氮比例具有较好的减氮效应^[6-7]。烤烟基肥中添加微生物菌剂可提高烟叶产量、产值及品质，也可减少氮肥施用^[8]；施用生物炭基肥可改善土壤功能细菌群落结构，显著提高减氮条件下的土壤养分积累并保障烟株成熟期养分需求^[9]；施用生物有机肥不仅可改良土壤和减少氮肥用量，而且还具有防控烟草青枯病的效果^[10]。施用土壤改良剂可促进烤烟根系生长，提高减氮条件下的烟叶产量和质量^[11]；施用腐殖酸碳肥可促进烤烟根系生长，提高氮肥施用效果^[12]；采用促根灌蔸肥并适当减少基肥氮比例的促根减氮施肥模式，在促进烤烟根系生长的情况下提高根系对氮肥的吸收，提高稻茬烤烟种植经济效益和环境效益^[13]。针对湖南烟稻复种区雨水多的特点，如何通过合理基追肥氮比例并搭配适宜的施氮量来减少氮肥用量的研究报道较少，特别是对烤烟养分积累与分配及肥料利用效率的研究还是空白。据此，本研究采用氮用量和基追肥氮比例的双因素试验方法，探讨其对烤烟氮磷钾养分积累与分配、烟叶产量和产值、肥料利用率的影响，为南方烟稻复种区制定烤烟施肥技术提供理论依据和技术支撑。

在烟株生长过程中，氮、磷、钾是不可或缺的三大营养元素。烤烟对氮、磷、钾养分的吸收受施肥水平、根系发育、土壤养分供应等的影响，其产量和质量也与氮、磷、钾养分的吸收及在植株内的分配密切相关^[19-20]。烟株积累的氮、磷、钾养分主要分配给叶片，且随烤烟生长，养分在叶片的占比减少，这与多数人的研究结论一致^[21-23]。施氮水平能引起植株氮磷钾养分吸收和分配的差异，且合理的施肥模式能显著提高氮肥的肥料利用率^[24]。本研究表明，随氮用量增加，烟株氮、钾积累量增加，这说明施用氮肥与烤烟的生长发育密切相关，与前人研究结果相似^[23-24]；A₃处理在圆顶期各器官钾积累量无显著差异，以及磷积累量与氮用量规律不明显，这可能与烤烟后期供肥主要来自土壤供肥有关^[25]。

肥料氮是烤烟的主要氮素来源之一。改变氮肥施用时期对肥料氮在土壤中的残留和分布有显著影响，适当延后氮肥追施时期或增加追肥氮比例有利于减少肥料氮的损失^[26-27]。增加追肥氮比例能够减少肥料氮的损失，提高肥料氮的利用率^[5-6]；在多雨烟区的烤烟追肥氮比例由50%提高到65%时，上部烟叶营养得到改善，烟叶产值和烟叶质量均得到提升^[28]。本研究表明，减少基肥氮比例可增加烟株的氮积累总量，显著提高烟叶产量和产值，以及提高氮肥利用效率和氮、磷、钾的偏生产力与偏生产效益；这与前人的研究结果一致^[5-6,26-28]。南方稻茬烤烟大田前期常遇低温多雨天气，农田土壤养分流失迅速，过多的基肥氮会增加肥料流失率^[3]，从而降低肥料利用率，影响烤烟生长和烟叶产量、产值^[3,28]。

烤烟对氮素敏感，不适量或不适时的氮素供应均会造成烟叶产量和质量下降。施氮水平对烟株氮磷钾积累与分配具有重要影响，适时提供烟株氮素是提高烟叶产量和质量的有效措施。在广东多雨烟区，追肥氮比例偏高条件下适度加大施氮量才能有效满足不同生育期烤烟氮养分需求，对促进烤烟氮素吸收利用、增产增效有显著作用^[29]，这与本研究结果基本一致。本研究表明，烟叶产量和产值随施氮量增加而增加，随基肥氮比例降低而增加，以施氮量为180 kg/hm²和基追肥氮比例为3∶7的处理烤烟产量最高。因此，在烤烟生产中更需要合理施用氮肥，以实现烟叶产量、产值和品质提升，以及氮肥高效和环境友好的目标。

4　结论

收起

本研究结果表明，随氮用量增加，烤烟氮积累量和烟叶产量、产值增加；减少基肥氮比例，可显著提高烟株氮积累量和烟叶产量与产值，以及显著提高氮肥的利用率和氮磷钾肥的偏生产力、偏生产效益。氮用量和基追肥氮比例及其互作对烤烟氮积累的贡献率分别为42.89%、29.63%、27.47%，对磷贡献率分别为38.62%、24.12%、37.25%，对钾积累的贡献率分别为41.22%、21.24%、37.54%。因此，在烟稻复种区，氮用量对烤烟氮磷钾养分积累的影响最大，烤烟生产中减少基肥氮比例可提高烟叶氮积累量，有利于提高烟叶产量和产值及氮肥利用率。
