为构建邵阳市烤烟生产GAP体系和烟叶质量评价体系,通过对邵阳市烤烟生产区水质、空气及土壤等环境因子进行调查与取样分析,评价了实施GAP管理后的大气、水体及土壤等环境因子和烟叶质量。结果表明,邵阳市植烟区大气质量符合GB3095—2012一级标准,水体质量达到GB3838—2002三级以上标准,绝大多数植烟土壤质量符合GB15618—1995二级以上标准,水体、大气和土壤符合优质烤烟GAP生产要求。2013年实施烟草生产GAP体系后X2F、C3F和B2F烟叶主要化学成分协调性、烟叶外观质量及评吸质量比实施前均有较大提高。在选择适宜品种基础上,建立有效的环境监控体系,合理规划种植基地,按照烟草GAP管理要求构建配套的烟叶生产技术体系,是确保本区烟叶质量的重要途径。
In order to construct GAP system and tobacco quality evaluation system for flue-cured tobacco production in Shaoyang City, environmental factors such as air, water and soil after GAP management were evaluated through investigation and sampling of environmental factors such as water quality, air and soil in flue-cured tobacco production area in Shaoyang City And tobacco quality. The results showed that the air quality of tobacco planting area in Shaoyang City was in accordance with the first grade of GB3095-2012, the quality of water body reached the third grade or above standard of GB3838-2002, and the quality of most tobacco plants accorded with the second grade or above of GB15618-1995. The water body, atmosphere and soil Meet the high-quality tobacco GAP production requirements. After the tobacco production GAP system was implemented in 2013, the main chemical components of tobacco leaves X2F, C3F and B2F had better coordination, the appearance quality and smoking quality of tobacco leaves than those before implementation. Based on the selection of appropriate varieties, establishing an effective environmental monitoring system, planning the planting base rationally and constructing the supporting tobacco production technology system according to the GAP management requirements of tobacco are important ways to ensure the quality of the tobacco in this area.
