摘　　要：为探讨有机无机复合肥对烤烟产质量的影响,采用常规肥料干施和有机无机复合肥大穴环施,以‘K326’为材料,2015年在湖南省浏阳市淳口镇进行了对比试验。结果表明,有机无机复合肥大穴环施,对烤烟生长发育及其生理生化特性指标、烟叶经济性状和产质量有明显促进和提高作用;正常用量有机无机复合肥,移栽30、45、60、75和90 d后根系活力和硝酸还原酶活性最大,移栽60、75和90 d后烟叶净光合速率最大,产量产值最高,分别为2066.15 kg/hm^2和51 393.68元/hm^2。有机无机复合肥大穴环施,有利于促进烤烟生长发育和烟叶经济性状及产质量提高。In order to study the effects of organic - inorganic compound fertilizer on the yield and quality of flue - cured to-bacco ,experiment was carried out with the treatments of traditional fertilizer under dry application and organic - inorganic compound fertilizer under the big hole circulating application,K326 was used as material. The result was showed as fellow： the treatment of big hole circulating application of the organic - inorganic compound fertilizer obviously promoted tobacco growth and development, increased tobacco physiological and biochemical characters indexes, improved its economic traits and its yield and quality. The max root activity and NR activity of tobacco occurred at 30 to 90 days after transplanted with the treatment of application normal rate of the organic - inorganic compound fertilizer, and the biggest Pn value of tobacco occurred at 60 to 90 days after transplanted, and the highest yield and yield value reached at 2066. 15 kg/hm^2 and 51 393. 68 yuan/hm^2 respectively. The method of organic - inorganic compound fertilizer under the big hole circulation is fa-vor of the flue - cured tobacco growth and development, increasing its economic traits, yield and yield value.
