Ecological Adaptability and Comprehensive Evaluation of Tobacco Leaf Yield and Quality of 7 Tobacco Varieties in Lijiang Tobacco Planting Area of Yunnan Province
The paper aims to explore the ecological adaptability of different tobacco varieties in Lijiang tobacco planting area,select the dominant tobacco varieties suitable for local planting,and improve the yield,quality and leaf style of cultivation of tobacco.Using the main locally grown variety'Yunyan 87'as a control,a total of 7 tobacco varieties were selected for field experiments to investigate the growth and agronomic traits of tobacco during the field stage.The economic traits of each variety were counted and various quality indicators of cured tobacco leaves were evaluated.The results showed that the field growth period of'Yunyan 116'variety was shorter and the economic characteristics were better,the comprehensive quality of cured tobacco leaves from'PVH1452'and'Yunyan 121'was high,and the agronomic characteristics of the conventional main planting variety'Yunyan 87'were better,but the growth period was longer and the chemical composition was not coordinated.In the wet valley tobacco planting area with similar ecological environment in Lijiang City,'Yunyan 116'had strong ecological adaptability and good tobacco quality,and the economic benefits were high,which could be widely verified and promoted as the main local variety.The comprehensive quality performance of'PVH1452'and'Yunyan 121'tobacco leaves was excellent,but there was still a lot of room for improvement in yield and revenue.They can be further developed and researched as reserve varieties to enhance the regional characteristics of Lijiang.
