摘要
为揭示黄腐酸钾对烤烟提质增效的作用,采用田间试验研究了不同用量黄腐酸钾对烤烟生长发育、烟叶钾含量以及产量品质的影响。结果表明,施用黄腐酸钾,最大叶叶面积比对照增加9.9%~23.0%,烤后烟叶评吸得分提高0.9%~8.8%,中上等烟比例提高8.5%~14.0%,产值增加22.3%~31.6%。施黄腐酸钾能促进烤烟叶片发育,改善烤后烟叶评吸质量,提高经济效益。
A field experiment was conducted to investigate the effect of different application amounts of potassium ful- vic acid on growth, potassium contents, yield and quality of flue-cured tobacco. Compared with control group, experi- mental group in the maximum leaf area, smoking score, proportion of superior tobacco, the output value were increased by 9.9%-23.0%, 0.9% -8.8%, 8.5%-14.0% and 22.3%-31.6% respectively. The application of potassium fulvic acid could promote the development of flue-cured tobacco leaves, improve the quality of tobacco smoking and improve the economic benefit.
