摘要
研究不同施肥方式对烤烟生长发育及烟叶产量、质量的影响。结果表明,相比其他施肥处理,硝酸钾用作追肥,其余肥料作基肥处理综合表现最优。与全部肥料作基肥施用相比,将硝酸钾用作追肥,能够促进旺长及平顶期烟株发育,烟叶产量、产值分别提高12.80%和9.70%;中、上部烟叶颜色、油分及总分得分分别提高了2.50%~3.90%、4.83%~9.43%和1.68%~2.86%;中、上部烟叶钾含量提高了14.29%和16.89%,且烟叶内在化学成分更加协调。
A field experiment was designed to study effect of different fertilization mode on development of tobacco,yield and its quality.The results showed that compared with other fertilization treatments,potassium nitrate as topdressing and other fertilizers as basal fertilizer had the best comprehensive performance.Compared with the application of all fertilizers as basal fertilizer,potassium nitrate as topdressing can promote the development of tobacco plants in the growing and flat-topped periods,and the tobacco yield and output value are increased by 12.80% and 9.70%,respectively.The color,oil content and total score of middle and upper tobacco leaves increased by 2.50%~3.90%,4.83%~9.43% and 1.68%~2.86%,respectively.The potassium content of middle and upper tobacco leaves increased by 14.29% and 16.89%,and the internal chemical composition of tobacco leaves was more harmonious.
