为了寻求研制优质、高效、环保的烟草控释肥料所需的参考依据,采用田间试验研究了控释肥和烟草专用复合肥对烤烟光合特性、产量与质量及氮钾利用率的影响。结果表明:(1)当施氮量由90 kg/hm~2提高到150 kg/hm~2时,烤烟产量和产值均显著增加,上等烟比例和均价略有下降,各叶位烤后烟叶全钾含量提高或显著提高,烟碱含量显著提高,总糖与还原糖含量显著下降;(2)与烟草专用复合肥相比,控释肥可提高烤烟旺长期以后的叶片叶绿素含量,提高旺长期烟叶净光合速率、气孔导度、胞间CO_2浓度,但对蒸腾速率无明显影响;(3)与烟草专用复合肥比较,控释肥能使烤烟产量提高3%~7%,产值提高9%~16%,各叶位烤后烟叶全钾含...

In order to provide the reference for research and development of high-quality, high-efficiency and environmentally harmless controlled release fertilizers for tobacco, the effects of controlled release fertilizer (CRF) and tobacco-specific compound fertilizer (TCF) on photosynthetic characteristics, yield, quality of flue-cured tobacco, and N and K use efficiency were investigated. The results showed that (1) when the nitrogen application rate increased from 90 to 150 kg/ha, yield and output value of flue-cured tobacco significantly increased, the ratio of first-grade tobacco leaves and avera...
