摘要
探讨了腐植酸溶液、柠檬酸螯合微量元素溶液、聚天门冬氨酸溶液及鱼内脏腐熟液对烟草生理及产量、品质的影响，以期找出适合烟草生长发育的叶面喷施肥，为提高烟草产量及品质提供依据。结果表明，施用叶面喷施肥有助于增强烟叶抗氧化酶活性，提高根系活力。烟叶抗氧化酶活性以腐植酸溶液、鱼内脏腐熟液处理较高，根系活力以鱼内脏腐熟液、聚天门冬氨酸溶液处理较高。施用叶面喷施肥有助于提高烟叶的产量和品质，产量增加幅度为3．18％～36．72％，其中喷施腐植酸溶液提高烟叶产量效果最好，烟叶品质指标也在优质烤烟要求范围内。综合以上因素，烟草用叶面喷施肥以腐植酸溶液最佳。
The effects of humic acid solution,chelated-trace element solution,poly-aspartic acid solution and the rotten fish-innard liquid on physiological indexes,yield and quality of tobacco were studied,so as to find out the suitable foliar fertilizer to improve the tobacco yield and quality.The results showed that spraying foliar fertilizer enhanced the antioxidant enzyme activities and root activity of tobacco, and the antioxidant enzyme activities of the treatments spraying humic acid solution and rotten fish-innard liquid were higher,root activities of the treatments spraying rotten fish-innard liquid and poly-aspartic acid solu-tion were higher;spraying foliar fertilizer improved the quality and yield of tabacco,the yield increased by 3.18%—36.72%,the treatment spraying humic acid solution had the highest yield,and the quality of which was also within the range of the high quality flue-cured tobacco.Based on the above factors,the hu-mic acid solution was the best foliar fertilizer for tobacco.
