摘要: 为探明在干旱胁迫下4%赤霉素水剂、0.136%赤·吲乙·芸苔可湿性粉剂、0.01%芸苔素内酯可溶液剂、0.1% S-诱抗素水剂、6%抗坏血酸水剂共5种生物源植物生长调节剂对烤烟产质量的影响,通过田间试验,对烤烟农艺性状、经济性状、化学成分等指标进行测量分析。结果表明,团棵期喷施4%赤霉素水剂、0.01%芸苔素内酯可溶液剂后烟株生长最快,节距明显增大;喷施6%抗坏血酸水剂可增加叶数,达到21.6片,能够促进上部叶开片。植物生长调节剂可促进烟株对钾的吸收,烤后烟叶钾含量明显增加,6%抗坏血酸水剂在降低中下部叶烟碱含量上表现明显,4%赤霉素水剂在整体上降低烟碱含量表现较好。5种植物生长调节剂对烤烟经济性状有不同程度的影响,喷施6%抗坏血酸水剂经济性状最好。综合而言,在干旱胁迫下6%抗坏血酸水剂能够改善烟叶品质,提高烟叶经济效益。

Abstract: In order to investigate the effects of five plant growth regulators on the yield and quality of flue-cured tobacco, 4% GA3 water agent, 0.136% GA·IAA·BR wettable powder, 0.01% BR soluble agent, 0.1% S-inducer water agent and 6% ascorbic acid water agent were selected, field experiment was conducted to measure and analyze the agronomic characters, economic characters and chemical components. The results showed that after spraying 4% GA3 water agent and 0.01% BR soluble agent, the growth of tobacco plants was the fastest and the pitch increased significantly at resettling stage; spraying 6% ascorbic acid could increase the number of leaves to 21.6, which can promote the opening of topper leaves. Plant growth regulators could promote the absorption of potassium by tobacco plants. The potassium content of flue-cured tobacco leaves increased significantly. 6% ascorbic acid water agent decreased the nicotine content of middle and lower leaves significantly, and 4% gibberellin water agent decreased the nicotine content as a whole. Five plant growth regulators had different effects on the economic properties of flue-cured tobacco, and praying 6% ascorbic acid agent was the highest. Taken together, 6% ascorbic acid could improve the quality of tobacco leaves and increase economic benefits under drought stress.
