菜籽饼对有机烟叶经济性状及理化特性的影响

Effect of Rapeseed Different Methods on Economic and Physicochemical Characteristics of Organic Tobacco

为提高菜籽饼利用率和有机烟叶经济价值,研究了发酵和直接施用菜籽饼2种方法对烟叶经济性状及理化特性的影响。结果表明:菜籽饼发酵与否,对有机烟叶的经济性状影响不大,菜籽饼发酵施用的烤烟产量和产值略高于直接施用。2个处理中除X2F烟碱含量略低外,C3F、B2F均在适宜范围内,菜籽饼发酵施用X2F、B2F烟碱含量高于直接施用;总氮含量变化趋势与烟碱变化趋势一致;总糖和还原糖含量均高于适宜范围;菜籽饼发酵施用的各等级含钾量均高于直接施用;2个处理氯离子含量均低于适宜范围,菜籽饼发酵施用X2F、B2F氯离子含量低于直接施用,菜籽饼发酵施用的各等级烟叶含梗率均高于直接施用,而叶面密度、叶长和叶宽小于其直接施用。

In order to improve utilization ratio of rapeseed cake and economic value of organic tobacco, the effect of application methods of rapeseed cake on economic and physicochemical characteristics were studied. The re- sults showed that rapeseed cake, fermentation or not, had little effect on economic characters of tobacco, yield and output value of fermentation application was slightly higher than direct application. The nicotine content of C3F and B2F was in the suitable range except X2F, B2F nicotine content of fermentation application was higher than direct application. Total nitrogen content was consistent with nicotine. Total sugar and reducing sugar con- tent of both treatments were in the range above. Potassium content of fermentation application was higher than direct application. Chlorine content of both treatments was less than suitable range, chlorine content of X2F and B2F of fermentation application was lower than direct application. Stem ratio of fermentation application was higher than direct application. Leaf density,length and width were on the contrary.
