Study on the Optimum Harvest Maturity of Flue-cured Tobacco Variety ‘K326’in Tobacco Growing Area in Qujing of Yunan
摘要
Abstract
In order to determine the optimum harvest maturity of flue-cured tobacco variety ‘K326’through seedlings trans-plant under plastic mulching method in Qujing.Through the analysis of mature characteristics of fresh tobacco leaves,sensory quality,chemical components and smoking quality of different harvesting time of middle and upper leaves.The results showed that,the appearance quality,chemical components and smoking quality were increased firstly and then decreased with the har-vest time delaed.Appearance quality of middle and upper leavers with higher scores was delayed harvest 5days,points 37.0 and 37.5 respectively.The suitable chemical components of middle leaves were conventional and delayed harvest 5 days.And the suitable chemical components of upper leaves were delayed harvest 5 and 10 days.The score of smoking assessment of de-layed harvest 5 was higher,points 65.20 and 63.70 respectively.And its had highest average price.In Qujing area,after seed-lings transplant under plastic mulching of flue-cured tobacco variety ‘K326’,it is appropriate harvesting time for middle leaves:131 days after transplanting date,more than 1 /2 to all of the midrib and lateral veins turning white,tomenta falling off and leaf angle between 80 and 90 degrees;for upper leaves:145-150 days after transplanting date,all of the midrib and later-al veins turning white,tomenta falling off and leaf angle between 110 and 120 degrees.关键词
