中文摘要:

本研究系统分析了烤烟新品种中烟特香301与中烟100干物质累积及养分吸收规律的异同。结果表明，两者地上部干物质累积趋势基本一致，均符合S型Logistic曲线：前者栽后0 ~ 35 d干物质累积较缓慢；36 ~ 95 d 快速累积，平均累积速率为 129.91 kg/hm²·d，之后趋于平缓。中烟特香301的干物质累积量与养分累积量均高于中烟100，且叶片钾含量显著高于中烟100，表明中烟特香301的养分需求量更多，尤其是钾肥需求量。

英文摘要:

This study systematically compared the patterns of dry matter accumulation and nutrient uptake between the newly bred flue-cured tobacco cultivar 'Zhongyan Texiang 301' and 'Zhongyan 100'. The sults showed that the aboveground dry matter accumulation in both cultivars followed an S-shaped logistic curve. For 'Zhongyan Texiang 301', accumulation was relatively slow during 0 to 35 days after transplanting, accelerated markedly from 36 to 95 days, with an average accumulation rate of 129.91 kg/hm²·d and then gradually slowed. Both dry matter and nutrient accumulation in 'Zhongyan Texiang 301' were greater than those in 'Zhongyan 100', and the potassium concentration in its leaves was significantly higher, indicating a greater demand for nutrients, especially potassium fertilizers, in 'Zhongyan Texiang 301'.
