| 摘 要： | 在不同的施氮水平下，对湘东烟区烤烟干物质的积累规律进行了初步的研究。结果表明，在每公顷施纯氮127．5kg的水平下，根、茎、叶干物质积累量较高，到圆顶时分别为78．20，74．66和128．48g，相对增长量分别是不施氮处理的4．33，2．967和1．355倍，相对增长速度分别为2．060，1．819，2．198g／d，说明在当地的气候条件下，在每公顷施127．5kg纯氮的条件下，撂烟有较高的生物学产量。

| Abstract: | A preliminary research on dry matter accumulation trend of flue-cured tobacco was conducted under different nitrogen application rate in East Hunan. The results showed that dry matter accumulation amount of roots,stems and leaves were greater under condition of N 127.5 kg/hm^2,and they were 78.20,74.66 and 128. 48 g/plant respectively at roundshape stage. The relative increment was 4. 33,2. 967 and 1. 335 times to that of no N treatment respectively,and the relative increasing speed was 2. 060, 1. 819 and 2. 198 g/d respectively. So application N 127. 5 kg/hm^2 could bring flue-cured tobacco a higher biological yield under conditions of local climate. |
