摘要
[目的]研究施钼对烤烟烟叶常规化学成分和产质量的影响。[方法]采用大区对比试验,对云烟85进行喷施钼肥处理。[结果]喷施钼肥对烟叶的糖、烟碱、氯等含量有明显影响,增糖降碱作用显著;喷施钼肥可显著提高烟叶含钾量和含钼量,改善烤后烟叶化学成分的协调性;喷施钼肥能提高中上等烟的比例,改善烟叶油分和色泽。[结论]该研究可为烤烟合理施钼提供理论依据。
[ Objective ] The effects of foliage spraying molybdenum on common chemical composition,yield and quality of flue-cured tobacco were studied. [ Method ] Wide field comparative experiment was carried out. Molybdenum fertilizer was sprayed on Yunyan 85. [ Result ] Spraying molybdenum could influence the content of sugar, nicotine and C1- ,increase the content of sugar and decrease the content of nicotine of tobacco leaves significantly. Molybdenum application could increase the content of molybdenum and potassium significantly, improve chemi- cal composition harmony of tobacco leaves. Molybdenum application could significantly enhance the percentage of fine and middle grade tobac- co and improve color and oil content of tobacco leaves. [ Conclusion] The research could provide the theoretical basis for rational applying mo- lybdenum fertilizer in tobacco cultivation.
