摘要: 选取陕西3个典型生态区,通过田间小区试验研究不同形态氮肥和配施腐殖酸处理对烤烟化学成分和产质量的影响,为烤烟优质适产栽培提供理论及实践依据。结果表明,单施氮肥和氮肥与腐殖酸配施均可提高烟碱和氮含量,降低还原糖含量;钾和氯含量因不同地区表现有差异;氮肥配施腐殖酸能更好地协调烟叶各化学成分含量,其效果好于单施氮肥。烤烟产量表现为陇县>洛南>旬阳,产值表现为陇县与旬阳相当,且均小于洛南。单施氮肥和氮肥与腐殖酸配施均对烤烟产质量具有促进作用,且效果因地区而异;陇县适合的氮肥形态为酰胺态氮,洛南为铵态、硝态及酰胺态等量混合态氮,旬阳为硝态氮,且前2个地区配施腐殖酸的效果好于单施氮肥,而旬阳地区氮肥单施与腐殖酸配施效果相当。说明不同典型生态区,适宜的氮肥类型存在差异,且合理配施腐殖酸能更好地促进烤烟生长发育,提高烤烟产量,协调烟叶化学成分,改善烟叶质量。

Abstract: To provide a theoretical and practical basis for cultivation of flue-cured tobacco with high yield and better quality, a field experiment was conducted in three different ecological growing-tobacco regions in Shaanxi province. The effects of different types of nitrogen (N) fertilizers and combinations with humic acid (HA) on chemical composition, yield and quality characters of flue-cured tobacco were investigated. Both N fertilizers and combinations with HA increased contents of nicotine and N, but decreased reducing sugar content. Their effects on contents of potassium (K) and chlorine (Cl) were varied due to different ecological conditions. The combined application of N and HA more effectively modulated the content of chemistry components than single N treatment. Yield of tobacco leaves followed the order of Longxian>Luonan>Xunyang, however, the output value showed that Longxian was similar to Xunyang, and both of them were less than Luonan. Both N fertilizers and combinations with HA enhanced yield and quality of flue-cured tobacco in three ecological regions, and their positive effects were different in the three regions. Suitable N fertilizer forms were amide-N in Longxian, but combined-N with ratio of amide∶ammonium∶nitrate 1∶1∶1 in Luonan, and nitrate-N in Xunyang. The effects of N fertilizers combined with HA in Longxian and Luonan were greater than that of a single N application, and similar effects were obtained in Xunyang. It is suggested that different suitable N fertilizers should be applied in the various ecological regions, and N fertilizers combined with HA could more effectively promote growth and development, coordinated chemical components of tobacco leaf, and improved yield and quality of flue-cured tobacco than single N fertilizer in these ecological growing-tobacco regions.
