摘要： 为提高云南缺硼烟区的烟叶产质量,通过大田试验研究了叶面喷施硼肥对烤烟品种K326、云烟87的生长发育和产质量的影响。结果表明:叶面喷施硼肥后,K326、云烟87的叶面积系数、叶片干物质积累均显著增加;叶片中的硼、钾含量均增加,其中云烟87的钾含量增加比例较高;化学成分较协调,评吸总分增加。说明在土壤缺硼的区域,叶面喷施补充硼肥是促进烟株生长和改善烟叶品质的有效途径。

Abstract: It is recognized that boron is one of the essential trace elements on tobacco growth and development.In this work,the impact of boron fertilizer leaf spray on growth, yield and quality of flue-cured tobacco varieties namely 326 and Yunyan 87,was investigated in soil boron deficit soil located in Yunnan. The results showed that boron fertilizer leaf spray significantly increased the leaf area index and leaf dry material of K326 and Yunyan 87,whereas it did not significantly increased B and K concentrations. Spraying boron,tobacco aroma quality, aroma amount aftertaste becomes good,odor and irritant to reduce tobacco aroma and taste improve to smoking total scores improve. The results suggested that boron fertilizer leaf spray may provide an effective approach to promote the growth of tobacco and leaf quality.

Key words: Flue-cured tobacco, Boron, K326, Yunyan 87, Potassium content, Yield and quality
