烟秆生物质燃烧灰分替代烟草部分化学钾肥应用研究

Applied Research of Partial Substitution of Chemical Potassic Fertilizer with Burning Ash of To⁃bacco Stem Biomass

在烟秆生物质能源烟叶烘烤过程中,生物质颗粒燃料燃烧后产生的灰分,经检测钾含量为7.23%。田间试验表明,燃烧灰分替代部分化学钾肥后,烟株农艺性状、烟叶产量产值及烟叶化学成分的协调性都没有大的改变。因此,生物质燃烧灰分可作为钾肥替代部分化学钾肥在烟草生产中应用。

After the flue curing process of tobacco leaves with tobacco stem biomass, the potassium concentration was 7.23%. This field trial showed that partial substitution of chemical potassic fertilizer with burning ash of tobacco stem biomass would not change the agronomic trait, the yield, and the chemical constituent harmony of tobacco too much. Therefore, the burning ash of tobacco stem biomass could be applied as a partial substitution of chemical potassic fertilizer in the tobacco production.
