中微量元素肥配施对烤烟生物碱积累及产质量的影响
Effects of Combined Application of Medium and Trace Element Fertilizers on Alkaloid Accumulation,Yield,and Quality of Flue-Cured Tobacco
摘要
Abstract
This study investigated the effects of combined application of medium and trace element fertilizers on the alkaloid accumulation,quality,and yield of flue-cured tobacco,aiming to improve the yield and quality of flue-cured tobacco in Lianzhou.The flue-cured tobacco cultivar'Yueyan 97'was planted and subjected to four fertilization treatments:water(CK),chlorine-magnesium-boron fertilizers(W1),selenium-magnesium-boron fertilizers(W2),and calcium-magnesium-boron fertilizers(W3).The results showed that compared with CK,the three fertilization treatments significantly decreased the SPAD values in the upper leaves during the maturation stage and significantly increased the alkaloid accumulation in the roots,stems,and leaves during the maturation stage,and the increases followed the trend of W3>W2>W1.Compared with CK,the three fertilization treatments showed decreases in total sugar content,reducing sugar content,and sugar/alkaloid ratio and increases in total nitrogen content,nicotine content,and chemical components usability index of flue-cured tobacco leaves,with W3 showcasing the largest changes.Meanwhile,medium and trace element fertilizer treatments improved the sensory evaluation scores regarding aroma quality,miscellaneous gas,irritation,and sensory quality of flue-cured tobacco.Moreover,the fertilizers significantly increased the proportion of upper leaves and decreased the proportion of middle and lower leaves,thus enhancing the yield,production value,and average price,with W3 treatment showing higher yield,production value,and proportion of upper leaves and the highest proportion of top-grade tobacco.In conclusion,the combined application of medium and trace element fertilizers can improve the nicotine content,overall coordination of chemical composition,sensory quality score,and economic traits of flue-cured tobacco.Particularly,the combined application of calcium-magnesium-boron fertilizers showing the best comprehensive performance should be popularized in Lianzhou.关键词
