统计分析了2005—2011年某烟叶挑选场的非烟杂物种类及含量.结果表明,非烟杂物以人工合成类杂物含量最高,推测主要来源于采收之后的有关环节.下部叶的杂物含量显著高于上部叶.在采用帆布包装的烟叶原料中,非烟杂物含量显著低于麻片包装,说明改进包装方式有益于防治杂物混入烟叶.值得注意的是,近年来,非烟杂物的含量大幅度降低,表明烟农和管理人员的质量意识和管理水平显著提高.

s:Impurities in tobacco leaves purchased by X companies from 2005 to 2011 were measured in a selection workshop and their origin was analyzed. The results showed that the impurities were largely synthesized substance, indicating that the impurities came mainly from post harvest processes. Impurities in the lower leaves of tobacco were significantly higher than the upper leaves because of the inclusion of impurities from the ground at harvest. Careful harvest could thus decrease the impurities in tobacco leaves. Canvas packing could prevent effectively against impurity entrance into tobacco leaves whereby to decrease impurities compared to linen packing. It was worth noticing that impurities in tobacco leaves decreased greatly in recent years, which indicates obvious improvement of quality control and management of both farmers and managers.
