摘要
通过对鄂西烟区16个县市2005-2011年烤烟外观质量、感官质量、化学成分和物理性状总分与烤烟大田期(5-9月)平均气温距平(dt)、日照时数距平(ds)和降水距平百分率(dpr)的相关分析和显著性检验,确定影响鄂西山区烤烟品质的关键气候因子及关键期,并采用重要性指数对主要影响因子进行了排序。结果表明,鄂西"清江源"烟区大田前期和后期气温较低、"金神农"烟区旺长期干旱、成熟后期降水过多对烤烟品质有重要影响。
The appearance quality,sensory quality,chemical composition and physical characteristics of tobacco from 16cities and towns in western Hubei flue-cured tobacco areas from 2005to 2011and the average temperature departure(dt)of tobacco field period(5to 9),sunshine duration departure(ds)and precipitation departure percentage were investigated to determine the key climatic factors and critical period affecting the quality of flue-cured tobacco in the mountain area of western Hubei Province.The main factors were further ranked by the index of relative importance.The results indicated that the temperature in Qingjiangyuan fields is lower during earlier and later period,while Jinshennong area suffers long period of drought and excessive rainfalls during the late mature period,which causes significant impact on the quality of flue-cured tobacco.
