Measures to Improve C2F Grade Quality in Wannan Anhui Tobacco Growing Areas

为提高皖南烟区C2F等级质量,对本部位正组率偏低、等级合格率不高的问题进行了分析,并采取了针对性的解决措施。结果表明,2019年度较2018年度本部位正组率提升7个百分点,混部位和含青、挂灰烟叶明显减轻,混上部叶和下部叶比例下降3个百分点。

To understand the field growth situation of flue-cured tobacco in Wannan Anhui tobacco area and to con⁃ duct uniformity analysis, laying a good foundation for tobacco homogenization production.The agronomic traits were determined and analyzed in Xuancheng and Wuhu cities, Xuanzhou, Wuhu, Nanling, Langxi, Jingde and Jing coun⁃ ties. There were no significant differences in plant height, stem circumference, upper leaf length and upper leaf width among the districts(counties), and the field uniformity was better. There were significant differences in node spac⁃ ing, number of leaves left in Langxi County, middle leaf length in Nanling County and middle leaf width in Jingde County. Combining with the analysis of mean and evenness, the field growth of flue-cured tobacco in Wannan Anhui is more uniform, Langxi County is weaker, Nanling County is stronger, and the field growth of other districts(coun⁃ ties)is more consistent.
