不同施肥量对闽烟9号、FL57产质量的影响

Effects of Different Fertilization Amounts on Yield and Quality of Flue-Cured Tobacco Varieties Minyan 9 and FL57

为探讨赣州烟区生态环境下闽烟9号、FL57的适宜施肥量,试验采用列区设计,设高、中、低3种施肥水平,施肥量为主处理,品种为副处理,共12个处理组合,研究不同施肥量对不同品种烟叶产质量的影响。结果表明:在试验区土壤肥力条件和3种施肥水平下,烤烟的产量、均价、产值、上等烟率和上中烟率等主要经济性状,存在品种与施肥量显著的互作效应。闽烟9号高肥处理产量、产值最高,但原烟的化学成分协调性不及中肥处理;FL57在高肥处理时,中部原烟的化学成分协调性较好。闽烟9号以中肥~高肥最适宜,FL57以高肥最适宜。

To explore the suitable fertilization amounts for two flue-cured tobacco varieties Minyan 9 and FL57 under the ecological environment of Ganzhou tobacco growing area,the experiment was conducted in a split-plot design with three fertilization levels(high,medium and low);fertilization amount was defined as the main treatment,and variety as the secondary treatment;a total of 12 treatment combinations were used to study the effects of different fertilizer rates on tobacco yield and quality.The results showed that at three fertilization levels based on the same soil fertility,there were significant interaction effects between various varieties and fertilizer amounts in the main economic traits including yield,average price,output value,premium and medium-premium tobacco rates.The yield and output value of Minyan 9 were the highest at the high fertilization level,but the chemical constituents coordination of its original fluecured tobacco was not as good as that at the medium fertilization level.At the high fertilization level,FL57 got a better coordination of chemical constituents in original flue-cured tobacco from the middle part of stems.Medium to high fertilization level was the most suitable for Minyan 9,and the high for FL57.
