氮肥形态对雪茄茄芯烟叶产质量及氮素利用效率的影响
Effects of nitrogen fertilizer form on yield,quality and nitrogen use efficiency of cigar filler tobacco
摘要
Abstract
To clarify the regulatory effects of nitrogen fertilizer form on the yield and quality of cigar filler,a field experiment was con-ducted using the cigar filler variety Chuxue 14(CX-14)to investigate the effects of ammonium nitrogen(NH4+),nitrate nitrogen(NO3-),and their mixed ratios on agronomic traits,yield benefits,chemical components,and sensory quality.The results showed that the mixed application of ammonium and nitrate nitrogen most significantly promoted plant height,stem girth,and leaf number of CX-14 during the later growth stage.All nitrogen application treatments significantly increased the yield and output value of both the cigar binder and filler,with the ammonium-to-nitrate ratio of 3∶1 treatment being the most effective.Nitrogen application increased the contents of nicotine,potassium,and nitrogen,while significantly decreasing the contents of reducing sugar,total sugar,and chlo-rine.The ammonium-to-nitrate ratio of 3∶1 treatment resulted in the highest nitrogen agronomic efficiency,nitrogen uptake efficien-cy,and dry matter mass.The ammonium-to-nitrate ratio of 3∶1 treatment achieved the highest overall sensory score(80 points),with significant improvements in aroma nuance and smoothness.This treatment synergistically optimized carbon and nitrogen metabolism and ion absorption,thereby enhancing the agronomic traits,yield,quality,and nitrogen use efficiency of cigar filler tobacco,and comprehensively improving the sensory quality of cigar tobacco leaves.关键词
