施用生物钾肥后减少化学钾肥对烤烟致香物质和评吸质量的影响

采用大田试验研究了施用生物钾肥后减少化学钾肥施用量对烤烟致香物质和评吸质量的影响.结果表明,施用生物钾肥后减少化学钾肥不会降低烟叶中主要致香物质含量和总致香物质含量,以减少化学钾肥14％的处理烟叶总致香物质含量和主要致香物质含量较高;施用生物钾肥后减少化学钾肥处理烤烟评吸质量较好,经济效益较高.但研究也发现,上述结果具有不稳定性,因此,针对不同烟区生物钾肥的研制和施用还有待于进一步的研究.

Effects of Decreasing Chemical Potassium After Biotic Potassium Application on Aroma Components and Smoking Quality in Flue-cured Tobacco Leaves

The effects of decreasing chemical potassium after application of biotic potassium on content of aroma components and smoking quality in flue-cured tobacco leaves were studied by field experiments. The results showed that application of decreasing chemical potassium after biotic potassium application did not reduce contents of total aroma components and major aroma components and the treatment of decreasing chemical K2O by 14% was better. The application of decreasing chemical potassium after biotic potassium application also could obtain good smoking quality and high economic benefit, but this result was unstable and needs further study for developing and applying biotic-potassium fertilizer.
