摘　　要：为明确纳米叶面肥在烟草生长中最佳喷施时期及其作用,在云南玉溪澄江烟区开展田间试验,研究了纳米碳叶面肥(NCF)在不同时期对烟草品质的影响,叶面喷施NCF对烟叶总氮含量有显著的提升效果,与CK相比,中、上部烟叶平均分别提升7.37%与14.45%。还原糖平均降低了17.41%;对烟碱含量有显著的降低效果,中、上部烟叶中烟碱含量平均分别降低了23.84%、33.87%。且NCF不同时期喷施均显著提高了中部烟叶钾含量,平均提高了12.50%。4个喷施时期处理间,其中T1处理(在团棵期、旺长期和打顶期进行3次喷施)对烟草品质提升最大。总之,叶面喷施NCF后,使烟草不同程度地提氮增钾、降烟碱。In order to determine the optimal application period of nano-foliar fertilizer in tobacco growth and its role,a field experiment was conducted in Chengjiang tobacco area of Yuxi,Yunnan Province to study the effects of nano-carbon foliar fertilizer(NCF)on tobacco quality at different periods.NCF spraying on leaves significantly increased the total nitrogen content of tobacco leaves.The average increase of middle and upper tobacco leaves was 7.37%and 14.45%respectively.Reducing sugar decreased by 17.41%on average.The nicotine content in middle and upper tobacco leaves decreased by 23.84%and 33.87%respectively.In addition,the potassium content of central tobacco leaves was significantly increased by 12.50%on average when NCF was applied in different periods.Among the four spraying periods,T1 treatment(spraying three times in the group growth period,flourishing period and peak period)had the greatest impact on the quality of tobacco.In conclusion,after spraying NCF on the leaf surface,the tobacco can improve nitrogen,increase potassium and reduce nicotine in different degrees.
