摘要:

为探究叶面喷施钾肥与鼠李糖脂混合液对烟叶油分含量和产质量的影响,以喷施清水为对照(CK),设置6个处理:T1,叶面喷施0.06 mol·L-1 K2HPO4;T2,叶面喷施0.06 mol·L-1黄腐酸钾;T3,叶面喷施120 mg·L-1鼠李糖脂;T4,叶面喷施0.06 mol·L-1 K2HPO4+120 mg·L-1鼠李糖脂;T5,叶面喷施0.06 mol·L-1黄腐酸钾+120 mg·L-1鼠李糖脂。测定各处理对烟叶碳氮代谢酶活性、油分品质、中性致香物质和产质量的影响。结果表明,喷施叶面钾肥可促进腺毛发育并提高烟叶油分,且与鼠李糖脂混合喷施效果优于单独喷施。其中,黄腐酸钾与鼠李糖脂混合喷施效果最佳,喷施后烟叶腺头饱满、发育完善,分泌能力增强,烤后烟叶腺毛分泌物含量和石油醚提取物含量均有所提高。同时,叶面喷施钾肥可协调烟叶碳氮代谢,以黄腐酸钾与鼠李糖脂混合喷施效果最好,其蔗糖合成酶活性较CK提高21.85%,硝酸还原酶活性较CK降低23.52%。此外,该处理还能协调烤后烟叶常规化学成分,提升中性致香物质含量,其中中性致香物质总量较CK提高43.27%;烤后烟叶总糖、还原糖和钾含量分别较CK提高3.96、3.86和0.34百分点,烟碱和总氮含量分别降低0.35、0.26百分点。叶面钾肥与鼠李糖脂混合喷施效果优于单独喷施,其中黄腐酸钾与鼠李糖脂混合喷施效果最佳。该研究结果为利用叶面钾肥与鼠李糖脂混合喷施提升烟叶油分和产质量提供了依据。

Abstract:

To investigate the effects of foliar spraying of potassium fertilizers mixed with rhamnolipid on tobacco leaf oil content, yield, and quality, with spraying clear water as the control (CK), six treatments were set up: T1, foliar spraying of 0.06 mol·L-1 K2HPO4; T2, foliar spraying of 0.06 mol·L-1 potassium fulvate; T3, foliar spraying of 120 mg·L-1 rhamnolipid; T4, foliar spraying of 0.06 mol·L-1 K2HPO4+120 mg·L-1 rhamnolipid; T5, foliar spraying of 0.06 mol·L-1 potassium fulvate+120 mg·L-1 rhamnolipid. The effects of each treatment on carbon and nitrogen metabolism enzyme activities, oil quality, neutral aroma components, yield, and quality of tobacco leaves were determined. The results showed that foliar spraying of potassium fertilizers promoted glandular hair development and increased tobacco leaf oil content, and the effect of mixed spraying with rhamnolipid was superior to spraying alone. Among them, mixed spraying of potassium fulvate and rhamnolipid yielded the best results. After spraying, tobacco leaf glandular heads were plump and well-developed, with enhanced secretion capacity. The content of glandular hair secretion and petroleum ether extract in cured tobacco leaves increased. Meanwhile, foliar spraying of potassium fertilizers coordinated carbon and nitrogen metabolism in tobacco leaves, with the mixed spraying of potassium fulvate and rhamnolipid showing the best effect. Its sucrose synthase activity increased by 21.85% compared with CK, while nitrate reductase activity decreased by 23.52% compared with CK. Additionally, this treatment coordinated the conventional chemical components of cured tobacco leaves and increased the content of neutral aroma components, with the total amount of neutral aroma components increasing by 43.27% compared with CK; the contents of total sugar, reducing sugar, and potassium in cured tobacco leaves increased by 3.96, 3.86, and 0.34 percentage points, respectively, compared with CK, while the contents of nicotine and total nitrogen decreased by 0.35 and 0.26 percentage points, respectively. Mixed foliar spraying of potassium fertilizers and rhamnolipid was more effective than spraying alone, with the combination of potassium fulvate and rhamnolipid yielding the best results. This study provides a basis for using mixed foliar spraying of potassium fertilizers and rhamnolipid to enhance tobacco leaf oil content, yield, and quality.
