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.

@@@@Effects of different combinations of slow-release potassium fertilizer (SRPF), conventional potassium fertilizer (CPF) and fulvic acid potassium (BSFA) on petroleum ether extracts and neutral aroma constituents in flue-cured tobacco leaves were studied with treatment T1 (CPF) as control. Results showed that T4 (SRPF, CPF and BSFA) led to the highest level of petroleum ether extracts, various types of aroma constituents and total neutral aroma constituents in upper leaves, and the second highest level in middle leaves. It was concluded that T4 was the optimum treatment.
