适宜凉山产区烟叶质量的植烟密度研究
Study on the Suitable Tobacco Planting Density for the Quality of Tobacco Leaves in Liangshan Area
摘要
Abstract
[Objective]The research aimed to study the suitable planting density of tobacco to highlight the quality of tobacco leaves in Liang-shan area.[Method]Yunyan 85 was used as the test material,and four tobacco planting density treatments were set up in the plot comparison test.Under the two row spacing transplanting specifications,the row spacing was used for the test.[Result]The agronomic traits of D1 and D2(900 and 1 000 plants/hm2)were better.The average price of flue-cured tobacco leaves and the proportion of superior tobacco leaves after treatment D1 were higher,and the economic benefits were better.The appearance quality evaluation score of D1 was the highest and the per-formance was better.When the row spacing was 120 cm,the content of total sugar and reducing sugar in treatment D1 was higher,the content of nicotine was higher and suitable,and the ratio of potassium to chlorine was suitable.When the row spacing was 110 cm,the nicotine con-tent of treatment D1 was suitable,the ratio of nitrogen to alkali was the closest to the optimal value,and the ratio of potassium to chlorine was the highest and suitable,which made the chemical composition of the treatment better.The aroma quality,aroma quantity,aftertaste and total score of sensory quality of tobacco leaves treated with D1 were higher and the quality grade was better.[Conclusion]The suitable planting density of tobacco leaves in Liangshan tobacco area was 900 plants/hm2,and all indexes of this treatment performed well.关键词
