烟草施用硒矿粉等硒肥对烟叶生长及品质的影响

Effect of Selenium-rich Organo-mineral Fertilizers on Yield and Quality of Tobacco Leaves

通过田间试验研究了施用硒矿粉、含硒复合肥和叶面肥对烟叶生长、内在品质和硒含量的影响。结果表明,硒矿粉、含硒复合肥和叶面肥对烟株农艺性状、烟叶产量和产值没有显著影响,但施用硒矿粉、含硒复合肥可提高烟叶硒的含量,改善烟叶的外观质量和内在品质。当硒矿粉的用量达到50 kg/667m2左右时烟叶硒含量达到最高,进一步增加用量对烟叶硒含量没有明显的影响。

We conducted field experiments in an attempt to access various impacts of using Selenium-rich Organo-Mineral Fertilizers on the roots of tobacco, especially the production quantity of tobacco, ,internal quality and selenium concentrations of tobacco. The results indicated that Selenium-rich Organo-mineral Fertilizers did not have negative effects on tobacco growth. On the contrary, they increased the output, improved the appearance and internal qualities of tobacco, and increased the concentration of selenium in tobacco. We did two plot experiments from 2009 to 2010, and one field experiment in 2010. The plot experiment in 2009 showed that the concentration of selenium in tobacco increased by 35.3% in treatment 3, as well as by 37.3% in treatment 4 compared to CK. Also, the selenium concentration increased by 45.8% in field experiment in 2010. The appropriate amount of selenium-rich Organo-mineral fertilizer was 750 kg/ha.
