摘要
[目的]研究不同土壤类型烟叶叶片中氮、烟碱及蛋白质含量的变化,确定适合的植烟土壤,生产出卷烟工业企业需要的原材料.[方法]对调制后的烟叶样品经烘干并粉碎过40目筛,采用自动分析仪法测定总氮和烟碱含量,间接分析法测定蛋白质.[结果]对不同土壤类型烤后烟叶氮含量的多重比较分析结果表明,氮含量平均值变化范围为1.1％ ～1.2％.暗棕壤烤后烟叶的氮含量最高,河淤土的氮含量次之,黑钙土的氮含量位居第三.不同部位烟叶间烟碱含量表现为上部叶＞中部叶＞下部叶,变化范围为1.5％～2.1％;烟叶蛋白质含量在不同部位、不同土壤类型间的差异不显著.[结论]根据东宁县烟区实际的自然条件及气候特点,建议在烤烟种植土壤上进行调整和转移,选择黑钙土及河淤土地块,尽量避免在暗棕壤上种植,从而减少烤烟叶片内主要含氮化合物的含量,同时还要依据卷烟企业的需求标准采取合理的栽培模式.
Abstract
[Objective] The changes of nitrogen,nicotine and protein content in tobacco leaf growing in different soil types were studied to determine the appropriate tobacco planting soil and produce raw materials needed in cigarette industry.[Method] After drying and crushing,total nitrogen and nicotine content in tobacco leaf were measured by automatic analyzer method,protein content was determined by indirect analysis method.[Result] Multiple comparison analysis indicated that,mean of nitrogen content ranged from 1.1％ to 1.2％.Nitrogen content from highest to lowest was dark brown earth,silt soil,chernozem;the order of nicotine content was upper leaf ＞ middle leaf ＞ lower leaf,varied from 1.5％ to 2.1％;there was no significant difference of protein content in different parts of tobacco leaf and soil types.[Conclusion] According to the actual natural conditions and climate features in tobacco planting area in Dongning County,chernozem and silt soil are recommended to cultivate tobacco,so as to reduce nitrogen compound content in flue-cured tobacco leaf.The reasonable cultivation model also should be adopted according to the demand of cigarette enterprises.
