| 摘 要： | 研究不同施铜量对烤烟生长、产量及养分吸收的影响。结果表明:施铜能提高烟叶的产量、产值、均价和上等烟比例,且与对照之间的差异达到显著水平,以1.35 kg/hm2处理最高。在0.45～1.35 kg/hm2施铜水平范围内可改善烟叶的品质。施铜对烟叶中铜含量有显著的影响,当施铜水平为0.45~0.90 kg/hm2时,烟叶中铜含量为最佳。因此,从烤烟的农艺性状、经济性状、品质和养分吸收方面综合考虑,建议云南省滇中优质烤烟合理的施铜水平以0.45～0.90 kg/hm2为宜。 |

| Abstract: | The effects of different copper application level on growth,yield and nutrient absorption of flue-cured tobacco was researched.The results showed that copper application level could increase yield,output value and ratio of high grade leaves.The yied,output value and ratio of high grade leaves had significant different with them of CK.When copper application level was 1.35 kg/hm2,the highest yield,output value and proportion of superior grade of leaves could be obtained.The quality was improved with copper application level being 0.45～1.35 kg/hm2.The content of copper in tobacco leaves was improved with copper application level being 0.45 ~0.90 kg/hm2.Comprehensively considering agronomic characters,economic characters,quality and nutrient absorption,the optimum copper application level should be 0.45~0.90 kg/hm2 for high-quality flue-cured tobacco growth in Dianzhong city of Yunnan province. |
