采用田间试验,以T1(普通钾肥)为对照,研究了缓释钾肥及其与普通钾肥、黄腐酸钾的配施对烤烟石油醚提取物和中性致香物质含量的影响。结果表明T4处理(缓释钾肥+普通钾肥+黄腐酸钾)上部叶石油醚提取物含量、各类型致香物质含量和中性致香物质总量均高于其它处理,中部叶石油醚提取物含量和中性致香物质总量仅低于T3(缓释钾肥+普通钾肥),且其上部叶和中部叶分别有24和16种致香物质含量高于其它处理,是最优施钾处理。
Field experiments were conducted to compare the effects of slow release potassium fertilizer and its combination with common potassium fertilizer and potassium fulvate on the contents of petroleum ether extract and neutral aroma of flue-cured tobacco with T1 (normal potassium fertilizer) as control. The results showed that the content of petroleum ether extract, the content of aromatics and the content of neutral aromatics in the upper part of T4 treatment (slow release potassium fertilizer + normal potassium fertilizer + potassium fulvate) were higher than those of other treatments. The middle petroleum ether extract The total contents of aromatics and neutral aroma compounds were only lower than that of T3 (slow release potassium + common potash), and the contents of 24 and 16 aroma components in the upper and middle leaves were the highest deal with.
