摘要
Abstract
In order to understand the fertilizer requirement characteristics of flue -cured tobacco new varieties Yuyan 7 and Yuyan 9 in western Henan , taking Yunyan 87 as the control , we carried out the field experiment with two treatments to study the effects of different nitrogen fertilizer application rates on the agronomic traits and economic traits of flue -cured tobacco , as well as the chemical compositions and quality of the baked tobacco leaves .The results showed that the growth vigor of Yuyan 7 and Yuyan 9 was better , their yield was higher , chemical compositions were coordinative , and the economic benefits and sensory quality were the best when 37.5 kg/hm2 nitrogen was applied .In the treatment of 52.5 kg/hm2 nitrogen application , the growth vigor of these two new varieties was stronger , and their yield was higher , but their proportion of middle -superior tobacco leaves was obviously de-creased, and their economic benefits and sensory quality were lower than those in the treatment of 37.5 kg/hm2 nitrogen application. The pure nitrogen requirement of two new varieties was 22.5~37.5 kg/hm2 less than that of Yunyan 87.关键词
