摘要
为探究增施不同有机肥料对烤烟KRK26生长发育的影响,以烤烟KRK26为研究对象,通过大田试验,综合分析了施用烟草专用有机肥(CK)和增施微生物菌剂(T1)、有机肥(T2)、生物有机肥(T3)对德宏陇川烟区烤烟KRK26生育期、主要农艺性状、内在化学成分和经济性状的影响.结果表明:相较于CK,T1、T3处理下烤烟KRK26的大田生育期分别缩短了7、5 d;移栽后45、60、75 d烤烟的农艺性状以T1处理的表现最佳;各处理的经济性状均较CK有所提高;不同处理下的B2F、C3F和X2F烟叶的内在化学成分均有不同程度的改善.综上,T1处理对烤烟KRK26生长发育和产质量的作用效果最佳.
Abstract
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.
