Abstract:

In order to clarify the synergistic effect of trehalose alcohol,phosphate-solubilizing microorganisms and trace elements on the yield and quality of flue-cured tobacco,a field experiment was carried out with Yunyan 87 as the test material.The control(S1),trehalose alcohol(S2),trehalose alcohol+compound phosphate-solubilizing bacteria(S3),trehalose alcohol+compound phosphate-solubilizing bacteria+compound trace elements(S4)were set up to study the effects of different fertilization treatments on agronomic traits,conventional chemical components and aroma substances of flue-cured tobacco.The results showed that compared with S1,S3 and S4 could improve the effective leaf number and leaf width of flue-cured tobacco.S4 treatment was more helpful to coordinate the chemical composition of cured tobacco leaves.The contents of total sugar,total nitrogen and nicotine were increased by 12.18%,70.00% and 20.30%,respectively,and the contents of aroma substances such as carotenoids,phenylalanines and brown-reacting species.The results of comprehensive index analysis showed that the comprehensive indexes of S1-S4 treatments were 21.06,23.22,24.66 and 27.08,respectively,and the comprehensive indexes were ranked as S4>S3>S2>S1,indicating that the comprehensive performance of flue-cured tobacco under the treatment of trehalose alcohol combined with trace elements and microbial agents was the best,indicating that the synergistic effect between trehalose alcohol,phosphate-solubilizing bacteria and compound trace elements was obvious,which could be used as the optimal formula of trace elements and microbial special fertilizer for tobacco leaves.

Key words: Flue-cured tobacco, Trehalitol, Double micro fertilizer, Quality, Aroma substances
