| 摘 要： | 为了确定南平烟区种植红花大金元品种的适宜施氮量,2006~2008年在福建南平大横镇试验农场进行了红花大金元品种不同施氮量的小区对比试验,结果表明,不同氮肥用量对红花大金元的主要生育期影响不大,随着施氮量的增加,烟株茎围、最大叶面积、根系和地上部干物质积累量、产量、产值也随之增加,但是当施氮量超过82.5 kg/hm2后,增加氮肥用量,烤烟均价、上等烟叶比例、原烟外观和感观质量反而下降。综合结果表明,施纯氮82.5 kg/hm2处理的烤烟产质量处于最佳效果。

Effects of Different Nitrogen Application Rates on Yield and Quality of Hongda Flue-cured Tobacco in Nanping |

| Abstract: | In order to make sure the suitable application rate of nitrogen for "Honghuadajinyuan" flue-cured tobacco in Nanping area,the field experiments in the application of nitrogen were conducted in Nanping Branch of Fujian Tobacco Agricultural Sciences Research Institute during 2006~2008.The results showed that there were no significant differences in growth duration among different treatments.Leaf area,yield,output value,accumulation of dry roots,stems and leaves all increased along with the increase of nitrogen application rate,but when the application rate of pure nitrogen was more than 82.5 kg/hm2,the average price,high grade leaves,seeming and smoking quality of flue-cured tobacco were decreased.Therefore,applying 82.5 kg/hm2 pure nitrogen was the best to Hongda flue-cured tobacco in Nanping area. |
