纳米碳增效肥料对烟草农艺性状和经济指标的影响

摘要

In order to disclose the effects of nano-carbon synergistic fertilizer (NCSF) on agronomical characters and economic indices of flue-cured tobacco, and to assess the application prospect of NCSF in flue-cured tobacco production of southeastern China, a field plot experiment was conducted on K326 cultivar in 2014 with three treatments, i.e., experienced dosage of normal fertilizer (CK), equivalent experienced dosage of NCSF (T1) and reduced 20% experienced dosage of NCSF (T2). The tobacco agronomical character indices were surveyed during the rosette stage, fast growing stage and round top stage and the economic indices were assessed after grading the flue-cured tobacco leaves. It was showed that compared to CK, T1 could optimize the field agronomical characters, raise reasonably the single leaf weight and the yield of leaves, increase the proportions of medium and high class leaves and average price of leaves, and could increase the output value by 3 300 yuan/hm2. The above results proves the good application prospect of the nano-carbon in tobacco production in southeastern China.%为了明确纳米碳增效肥料对烟草农艺性状和经济指标的影响，评估其在我国东南烤烟种植区生产中的应用前景，2014年选用烤烟品种K326开展田间小区试验，设置了常规肥料经验用量(CK)、等量纳米碳增效肥料用量(T1)和减量纳米碳增效肥料用量(T2)3个处理，调查了烟草团棵期、旺长期和圆顶期的田间农艺性状，分析了烤后烟叶的经济指标。结果表明，与C K相比，T 1处理可优化烟草田间农艺性状，合理增加烟叶单叶重和产量，提高中上等和上等烟比例，提高烟叶均价，增加产值约3300元/hm2，纳米碳增效肥料在我国东南烟区具有良好的应用前景。
