摘要
采用田间试验,研究了不同缓释钾肥对烤烟农艺性状和品质的影响。结果表明:相比普通钾肥,缓释钾肥可以在不同程度上促进烟株的生长发育,但差异不显著。缓释钾肥可以提高烤后烟叶石油醚提取物含量,促进常规化学成分的协调,提高烟叶的钾含量,其中添加生物质炭的缓释钾肥的效果要明显优于添加腐殖酸的缓释钾肥。
A field experiment was conducted to investigate the effect of different slow -release potassium fertilizers on agro-nomic traits and quality of flue -cured tobacco.The results showed that compared to common potassium fertilizer,slow -release potassium fertilizers could promote the growth of flue -cured tobacco,but the difference was not significant.The slow -release potassium fertilizers could heighten the content of petroleum ether extract and promote the coordination of conventional chemical compositions,and improve the content of potassium in tobacco leaves.The effects of slow -release potassium fertilizer which be added biomass charcoal were clearly better than those of slow -release potassium fertilizer which be added humic acid.
