硒矿粉对烤烟经济性状、化学成分及硒含量的影响

Effects of Selenium Ore Powders Application on the Economic Characters, Chemical Constituent and Selenium Content of Flue-cured Tobacco

采用土壤施用硒肥的方法,研究了硒矿粉不同用量对烤烟农艺性状、经济性状、化学成分及烟叶硒含量的影响。结果表明,施用硒矿粉对烟株各个时期农艺性状无明显影响,对经济性状和化学成分协调性的影响明显,对烟叶硒含量增加的效果显著。在试验条件下,适宜的硒矿粉用量为1.0 kg/(66m2)。

Effects of different rates of selenium ore powders on agronomic characters,economic characters,chemical constituent and selenium content of flue-cured tobacco were studied by applying selenium ore powders in soil.The results showed that application of selenium ore powders had no obvious effect on agronomic characters during different stages,but significantly improved the economic characters and coordinated chemical constituent,increased the selenium content of cured tobacco.Under the conditions of this study,it was proper to apply selenium ore powders at 1.0 kg /（66 m2）.
