Effect of Classified Plaiting Method on Quality of Simplified Harvesting Tobacco
The feasibility of classified plaiting under light and simplified harvesting is helpful to accelerate the application of four light and simple stratified harvesting technologies.Based on this,this paper evaluated the effect of classified plaiting method on tobacco leaf quality from three aspects of appearance quality,sensory quality and chemical composition coordination.And the advantages and disadvantages of this measure combined with the output value of tobacco leaf,packing efficiency and the demand of curing house were analyzed.The results showed as follows:(1)classified plaiting method could increase the yield of tobacco leaf by 8.83％.According to the purchase price of tobacco leaf in 2023,the output value of tobacco leaf increased by 8320 yuan/hm2.(2)Classified plaiting method could improve the yield and proportion of tobacco of all grades(except for C3F).Classified plaiting method improved the appearance quality and chemical composition coordination of upper and lower leaves,and improved the sensory quality of C3F.(3)The average time spent on each cigarette clip increased by 1 minute,and the efficiency of the cigarette clip was low.The increase in the number of single-time cigarette clips increased the demand for the barn,resulting in a 22.99％reduction in the service capacity of the barn.Classified plaiting method can improve the quality grade composition of tobacco leaves and increase the quality and yield of tobacco leaves,but it will decrease the efficiency of packing process and increase the pressure of curing house service.The large-scale application of light and simplified harvesting technology also needs to explore effective measures to improve the efficiency of plaiting method,and moderately adjust the construction of infrastructure such as curing barns.
