增施不同种类有机肥对烤烟KRK26生长发育的影响OACSTPCD

Flue-cured tobacco KRK26 was taken as the research object,and the effects of different organic fertilizers on the growth and development of flue-cured tobacco KRK26 were studied through field experiments.Four treatments were set up in the experiment,namely,the application of tobacco special organic fertilizer(CK),adding microbial inoculant(T1),organic fertilizer(T2)and biological organic fertilizer(T3).The effects of different fertilization types on the growth period,main agronomic traits,intrinsic chemical components and economic traits of flue-cured tobacco KRK26 in Longchuan tobacco-growing area of Dehong were comprehensively analyzed.The results showed that compared with CK,the growth period of flue-cured tobacco KRK26 under T1 and T3 was shortened by 7 and 5 days respectively.The agronomic characters of flue-cured tobacco KRK26 under T1 at 45 d,60 d and 75 d after transplanting were the best.In the aspect of economic characters,all treatments were better than CK.At the same time,the intrinsic chemical components of B2F,C3F and X2F tobacco leaves were improved in different degrees.In conclusion,T1 was the best for growth,development,yield and quality of flue-cured tobacco KRK26.
