摘要 

[目的]研究镁肥对烤烟烟叶中主要化学成分和有机酸含量的影响。[方法]本试验以5个施镁水平(0、50、75、100、125kg/hm2)在攀枝花烟区开展大田随机区组试验。[结果]施镁水平在75~100kg/hm2范围内,烟叶中各项化学成分趋于协调平衡,最接近优质烟叶适宜含量范围。施镁水平为100~125kg/hm2时,上部叶和中部叶中非挥发性有机酸含量比对照分别增加9.31%和7.06%;上部叶和中部叶中高级脂肪酸含量比对照分别增加11.5%和16.1%。[结论]当攀枝花烟区施镁水平为100kg/hm2时,有利于改善烟叶中化学成分的协调性,促进烟叶有机酸含量的增加,为今后攀枝花地区烤烟施镁提供参考。

Abstract

[Purpose] In this work, the effect of magnesium fertilizer on the main chemical compositions and organic acids content in flue-cured tobacco leaves was investigated in Panzhihua tobacco planting areas.[Method] The field experiment was randomly divided different small field, which was setup five levels of magnesium (0, 50, 75, 100, 125kg/hm2).[Results] The results indicated that when magnesium application level was 75-100kg/hm2, the content of the main chemical compositions of tobacco leaf were suitable and most close to the appropriate content of high quality tobacco. Compared with CK, the content of the non-volatile organic acids in upper and middle leaves increased by 9.31% and 7.06%, respectively, when magnesium application level was 100-125kg/hm2. Moreover, the content of the higher fatty acids in upper and middle leaves increased by 11.5% and 16.1%, respectively.[Conclusion] Thus, the application of 100kg/hm2 magnesium fertilizer had positive effect on coordinating the chemical compositions and promoting the increase of the organic acids content. This study will provide the scientific basis for the application of magnesium fertilizer in Panzhihua area.
