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。
In order to clarify the impact of nano-carbon fertilizer on the agronomic traits and economic indicators of tobacco and evaluate its application prospects in the production of southeast flue-cured tobacco in China, field experiments were conducted with flue-cured tobacco variety K326 in 2014 to set the conventional fertilizer experience (CK ), The same amount of nano-carbon fertilizer (T1) and the amount of reduced carbon nano-fertilizer (T2) were studied. The agronomic traits of tobacco during the flowering stage, After the economic indicators of tobacco. The results showed that compared with CK, T1 treatment could optimize the agronomic traits in tobacco field, increase the single leaf weight and yield of tobacco leaves rationally, increase the proportion of middle and upper class and upper class tobacco, increase the average price of tobacco leaf and increase the output value about 3 300 yuan / hm ~ 2, nano-carbon fertilizer in the southeast of our country has a good prospect of application.
