摘要
2013年，对湖北省自育烤烟新品系HB032、HB061和HB112，在清江流域设点试验，探讨了不同氮肥施用量对其农艺性状、经济性状和品质性状的影响。结果表明，HB032和HB112随着氮肥施用量的增加，其产量、产值和品质也随之提高，到氮肥施用量为97．5kg／hm^2表现最好，随后降低。而HB061随着氮肥施用量的增加，其产量、产值和上等烟比例提高，到氮肥施用量为105．0kge／hm^2表现最好，但吸食品质以氮肥施用量以90．0～97．5kg／hm^2表现最好。综合来看，3个品系的氮肥施用量均以97．5kz／hm^2为宜。
In 2013, new flue-cured tobacco strains HB032, HB061 and HB112 bred in Hubei Province were demonstrated in the Qingjiang area. The effects of different application rate of nitrogen fertilizer on agronomic trait, economic character and quality traits of the new flue-cured tobacco strains were studied. The results showed that the yield, output value and quality of HB032 and HB112 were improved with the increase of nitrogen fertilizer. The effect of nitrogen application amount with 97.5 kg/hm^2 was the best, then decreased. The yield, output value and the proportion of superior leaves of HB061 was in- creased with the increase of nitrogen fertilizer. The effect of nitrogen fertilizer application amount with 105.0 kg/hm^2 was the best. The smoking quality of nitrogen application amount with 90.0, 97.5 kg/hm^2 was the best. In general, it is recommended that the application rate of nitrogen fertilizer is 97.5 kg/hm^2 for HB032, HB061 and HB112.
