摘要:

为明确烤烟新品种中川208在攀西烟区的适宜钾肥施用量,本研究设置了叶面喷施钾肥处理,通过比较不同钾肥处理下中川208的农艺性状、烤后烟叶经济性状、化学成分及感官质量,综合评价其施钾效果。结果表明,在旺长期后喷施1次钾肥可有效缓解中川208旺长期叶片的缺钾症状。在攀枝花试验点,喷施2次和3次钾肥处理的产量与产值较高,喷施1次钾肥处理的烤后烟叶化学成分协调性最佳,感官质量最优。在西昌大兴基地,增施钾肥增强了中川208的长势,喷施2次和3次钾肥处理的产量高于不喷施钾肥处理和喷施1次钾肥处理,而喷施1次钾肥处理的产值最高。在西昌农户试验点,喷施钾肥提高了中川208的产量,其中喷施1次钾肥处理的产值和上等烟比例均最高。综合3个试验点的结果,于中川208旺长期喷施1次钾肥,不仅能有效缓解缺钾症状,还有助于提高产值,并较好地保持烤后烟叶的评吸质量。

Abstract:

To determine the optimal potassium fertilizer application rate for the new flue-cured tobacco variety Zhongchuan 208 in the western Panzhihua tobacco-growing area, this study implemented foliar potassium fertilizer treatments. The effects of potassium application were comprehensively evaluated by comparing the agronomic traits, economic characteristics, chemical components, and sensory quality of tobacco leaves under different treatments. The results showed that one application of potassium fertilizer after the vigorous growth stage effectively alleviated potassium deficiency symptoms in Zhongchuan 208 leaves. At the Panzhihua trial site, treatments with two and three applications of potassium fertilizer resulted in higher yield and output value, while one application led to the most harmonious chemical composition and the best sensory quality of cured tobacco leaves. At the Xichang Daxing base, additional potassium application enhanced plant growth; treatments with two and three applications produced higher yields than those with zero or one application, while one application achieved the highest output value. At the Xichang farmer trial site, potassium application increased tobacco yield, with one application resulting in the highest output value and proportion of high quality tobacco. Overall, across the three trial sites, one application of potassium fertilizer during the vigorous growth stage of Zhongchuan 208 not only effectively alleviated potassium deficiency symptoms but also helped increase output value while maintaining good sensory quality of the cured tobacco leaves.
