摘要
为了确定中烟100合适的施肥水平及烟叶产量,通过1年2地点(山东沂水、费县)的田间试验,研究了高、中、低及零肥量对中烟100产量和质量的影响。结果表明,烟叶产量、均价等随施肥量的增加而提高,当施氮量达到105 kg/666.7m2时,上等烟比例和均价最高;高肥力下施氮75 kg/hm2、中等肥力下施氮142.5 kg/hm2时,烟叶感官质量最佳;中烟100需要较高的营养供应水平,获得较佳质量的产量低限为2250 kg/hm2。
Field experiments at two locations （Yishui and Feixian of Shandong Province） were conducted to investigate the effect of fertilizer application rates（high, medium, low, and null） on tobacco （var. zhongyan100） leaf yield and quality. The results showed that tobacco leaf yield and average price increased with the increase of fertilizer application levels. The superior leaf proportion and average price reached highest under the nitrogen level of 105 kg/ha. The best smoking test results were observed when nitrogen rate was 75 and 142.5 kg/ha for high and middle fertile soils, respectively. The results suggested that Zhongyan100 required high level of nutrient supply. To produce higher quality tobacco, the minimum yield of Zhongyan100 should be 2 250 kg/ha.
