纳米碳增效肥料对烟草农艺性状和经济指标的影响

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CK相比,T1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3 300元/hm~2,纳米碳增效肥料在我国东南烟区具有良好的应用前景。

Effects of Nano-carbon Synergistic Fertilizer on Agronomical Characters and Economic Indices of Flue-cured Tobacco

In order to ensure the effect of nano-carbon synergistic fertilizer (NCSF) on agronomical characters and economic index of flue-cured tobacco, and to assess the application prospect of NCSF in flue-cured tobacco production. A field plot experiment with three treatments, which were the experience consumption of normal fertilizer (CK), equivalent experience consumption of NCSF (T1) and reduced 20% experience consumption of NCSF (T2), was carried out by K326 cultivar in 2014. The tobacco agronomical character indexes were investigated during the rosette stage, fast growing stage and round top stage. The economic indexes were assessed after grading the flue-cured tobacco leaves. It was showed that compared to CK, the T1 could optimize the field agronomical characters, raise the single leaf weight and the yield reasonable, increase the proportion of medium and high class leaf and average price, and could raise the output value to 37010.85 yuan/hm2, the increasing amount reached to 3300 yuan/hm2. The result of the field plot experiment proved the evidence that the nano-carbon had good application prospect in tobacco production in Chinese Southeast tobacco planting area.
