施用生物炭、黄腐酸钾对云烟87烤烟产质量的影响

Effects of Increasing Application of Biochar and Fulvic Acid Potassium on Yield and Quality of Flue-Cured Tobacco Variety Yunyan 87

以云烟87为材料,采用田间小区试验法,研究在常规施肥的基础上配施生物炭、黄腐酸钾对烤烟产质量的影响。结果表明,增施生物炭和黄腐酸钾能够显著提高烟叶产量、产值和上等烟比例,改善烟叶的物理特性,化学成分更协调,致香物质含量和评吸质量也得到提高。总体效果以在常规施肥的基础上同时增施生物炭和黄腐酸钾的效果最好。

The field experiment was conducted to study the effects of the increasing application of biochar and fulvic acid potassium on the yield and quality of flue-cured tobacco. The results showed that with increasing application of biochar and fulvic acid potassium at the same time,the yield,output value and superior tobacco proportion of flue-cured tobacco could be significantly improved,the physical properties,aroma constituent contents and smoking quality also were improved,and the chemical components were more appropriate. Overall,the optimal treatment was to increasingly apply biochar and fulvic acid potassium at the same time.
