喷施植物生长调节剂对烤烟品质的影响
Effect of Plant Growth Regulators on Quality of Flue-cured Tobacco
摘要
Abstract
[Objective]To study the effects of plant growth regulators on stemming rate and other quality indexes of tobacco leaves by foliar spraying.[Method]Using Yunyan 87 as the test material,the effects of spraying plant growth regulators(6-BA,DA-6,LaCl3)on the appear-ance quality,physical index,chemical composition,sensory quality and economic shape of tobacco leaves after roasting were studied.[Result]Three treatments sprayed with plant growth regulators could significantly improve the appearance quality,single leaf weight,leaf weight,potassi-um-chloride ratio,nitrogen-base ratio,sugar-base ratio and sensory quality of flue-cured tobacco,and significantly reduce the stemming rate and nicotine of flue-cured tobacco,and among the three plant growth regulators,LaCl3 improved the most obvious indicators of flue-cured tobacco.[Conclusion]The use of plant growth regulators such as 6-BA,DA-6 and LaCl3 in the bud stage and the topping stage can effectively and signif-icantly improve the quality of flue-cured tobacco,reduce the stalk rate,and promote the growth and development of flue-cured tobacco.关键词
