摘要
为探讨不同生育时期增施钼肥对烤烟品质及经济性状的影响,以云烟87为材料,在旺长期、现蕾期和采烤前等量喷施钼酸铵。结果表明,现蕾期(T2)和采烤前(T3)喷施钼肥对烤烟综合品质提升效果优于旺长期(T1)。现蕾期喷施钼肥烤后烟叶橘黄,成熟度优于对照,外观品质综合得分较对照提高1.99%,且该处理能够降低烤烟厚度至优质烟叶要求,烟叶钾含量、钾氯比、氮碱比和化学成分综合得分分别较对照提高28.57%、10.61%、13.79%和13.89%,感官质量与对照无明显差异。采烤前喷施钼肥后对外观品质改善效果较小,但能够降低烤烟厚度,提升烟叶化学成分协调性,其钾含量、钾氯比、氮碱比、化学成分综合得分分别较对照提升64.76%、8.21%、25.86%和44.44%,且该处理感官品质综合得分高于对照。现蕾期和采烤前喷施钼肥烟叶综合品质得分分别较对照提高7.78%、14.24%,产值分别较对照提高4.87%、3.10%。现蕾期和采烤前喷施钼肥对烤烟产质量改善效果较佳,且以采烤前喷施略优于现蕾期。
In order to study the effects of molybdenum fertilizer on the quality and economic traits of flue-cured tobacco at different growth stages,Yunyan 87 was sprayed with equal molybdate at vigorous growth stage,budding stage and before harvest.The results showed that the comprehensive quality in budding stage(T2)and before harvest(T3)were superior to that in vigorous growing period(T1).After spraying molybdenum fertilizer at budding stage,the flue-cured tobacco leaves were orange,the maturity was better than the control,and the comprehensive score of appearance quality was increased by 1.99%compared with the control.The treatment could reduce the thickness of flue-cured tobacco to the requirements of high quality tobacco leaves,and improve potassium content,potassium chloride ratio,nitrogen alkali ratio and score of comprehensive chemical composition,which were increased by 28.57%,10.61%,13.79%and 13.89%,respectively,compared with the control.There was no significant difference in sensory quality between the treatment and the control.There was little improvement on appearance quality after spraying molybdenum fertilizer before harvest,but it could reduce the thickness of flue-cured tobacco and improve the coordination of chemical components.The potassium content,potassium chloride ratio,nitrogen-base ratio and the comprehensive score of chemical components were increased by 64.76%,8.21%,25.86%and 44.44%,respectively,compared with the control.The score of sensory quality the treatment was higher than that of the control.The comprehensive quality scores of flue-cured tobacco leaves sprayed with molybdenum fertilizer at budding stage and before harvest were increased by 7.78%and 14.24%,respectively,and the yield was increased by 4.87%and 3.10%,respectively.Spraying molybdenum fertilizer at budding stage and before harvest had better effect on improving yield and quality of flue-cured tobacco,and spraying before harvest was slightly better than that at budding stage.
