| 摘要 | [Objectives] To evaluate the effects of deep vertical rotary tillage combined with organic carbon fertilizer on the improvement of acidic mountain soils. [Methods] A field experiment was conducted comparing three treatments: deep vertical rotary tillage, deep vertical rotary tillage combined with liquid organic carbon fertilizer, and traditional cultivation. The impacts of these treatments on the growth, biomass accumulation, yield, and quality of flue-cured tobacco were investigated. [Results] Deep vertical rotary tillage enhanced the growth of tobacco roots and aerial parts, as well as the accumulation of dry matter, nitrogen, phosphorus, potassium, and nicotine. The combination of vertical deep rotary tillage with organic carbon fertilizer promoted tobacco root development, increased leaf area, and facilitated the accumulation of dry matter, nitrogen, phosphorus, potassium, nicotine, and chlorine, thereby leading to an increase in the yield of flue-cured tobacco. The application of liquid organic carbon fertilizer enhanced the potassium and sugar content of flue-cured tobacco, but it also resulted in an increased nicotine content. Therefore, flue-cured tobacco cultivation is recommended under acidic soil conditions in mountainous regions, employing deep vertical rotary tillage. [Conclusions] The application of liquid organic carbon fertilizers at the time of transplanting, combined with rooting solution irrigation, and again 20 d after transplanting combined with topdressing, effectively promotes the growth and dry matter accumulation of flue-cured tobacco. |
