施氮量对福建雪茄烟叶产量与品质的影响
Effects of Nitrogen Application on Yield and Quality of Fujian Cigar Tobacco
摘要
Abstract
This study aimed to investigate the effects of nitrogen application rate on the yield and quality of cigar tobacco in Fujian producing area.Using the cigar filler variety'Haiyan 204',field experiments were conducted with five nitrogen application treatments:0 kg/hm2(N0),120 kg/hm2(N8),180 kg/hm2(N12),210 kg/hm2(N14),and 240 kg/hm2(N16).Key indices including economic traits,smoking quality,agronomic traits,chemical components,physiological metabolism,and antioxidant enzyme activities were measured.The results showed that the N14 treatment yielded the best economic traits,superior smoking quality,and optimal agronomic traits.Compared with N0,the N14 treatment significantly increased the output value by 273.54%and significantly increased the maximum leaf area by 34.06%.With increasing nitrogen application,the chemical components and physiological metabolism indicators of cigar tobacco leaves generally exhibited a trend of increasing first,then decreasing and then increasing again.Under the N14 treatment,the total nitrogen and chlorine contents were relatively low,while reducing sugar and total sugar contents were moderate.The nicotine content was higher.Stress-resistant substances,such as soluble protein and peroxidase(POD),maintained higher levels.Nitrogen metabolism-related synthetase activities were relatively lower,but amylase and acid invertase activities were significantly enhanced.Comprehensive analysis indicated that under the N14 treatment,tobacco leaves demonstrated the highest economic performance,the best plant growth and appearance,more harmonious chemical composition,and improved plant resistance.For cultivating'Haiyan 204'in the Fujian region,the recommended pure nitrogen application rate is 180-210 kg/hm2.关键词
