摘　　要：田间试验研究了生物有机肥对烤烟体内氮、磷、钾积累、吸收和含量的影响。结果表明,烤烟施用生物有机肥提高了烟株体内氮、磷、钾的积累;烤烟对氮素的积累为T3>T2>T1>CK,单株分别积累氮素5.29、4.84、4.20、3.55 g;对钾素的积累为T2>T1>T3>CK,分别积累钾素4.92、4.59、4.58、3.92 g。施用生物有机肥对烤烟氮素吸收速率的影响是50d前较对照明显升高;对磷素为50 d前施用50%生物有机肥的处理较对照增加,而75%生物有机肥的处理则较对照低;对钾的吸收速率团棵后逐渐增加,50 d时达到高峰。施用生物有机肥增加了旺长期烟株体内氮、磷、钾的含量,促进了烟株生长,提高了烤后烟叶含钾量。A field experiment was conducted to study the effect bio-organic fertilizer application on accumulation, uptake and contents of N, P and K in flue-cured tobacco. The results showed that application of bio-organic fertilizer could improve the accumulation of N, P, K in tobacco plants. The accumulation in flue-cured tobacco plant, from high to low, was T3 （75% bio-organic fertilizer） 〉T2 （50%） 〉T1 （25%） 〉CK （0%） for N, and T2〉T1〉T3〉CK for K. For accumulation in separate plants, it was 5.29, 4.84, 4.20, 3.55 g for N, and 4.92, 4.59, 4.58, 3.92 g for K, respectively. In 50 days after transplantation, regarding uptake rate, it was definitely improved for N in all treatments of bio-organic fertilizer application, and for P it was improved in treatment of 50% but decreased in treatment of 75% bio-organic fertilizer application. For K, it gradually increased in rosette stage and reached peak around 50 days after transplantation. It is concluded that application of bio-organic fertilizer can improve the contents of N, P and K in tobacco plants of active growth stage, enhancing the growth and development of flue-cured tobacco in fields, and resulting in increased potassium contents of cured tobacco leaves.
