Abstract：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.
