| 摘 要： | 2001-2003年,分别在威宁、道真、安龙、瓮安、独山进行了不同施氮量(无机氮60 kg/hm2、90 kg/hm2和120 kg/hm2)与烟叶质量关系的研究.结果表明,施氮量对不同生态烟区烟叶产量、品质影响较大.在增施有机肥的基础上,随施氮量增加,烟叶产量提高;施无机氮为90 kg/hm2处理对改善烟叶香气、吃味等感官评吸质量有明显影响;高海拔的威宁施无机氮量应控制在60-90 kg/hm2范围内,其他烟区以施无机氮90-120 kg/hm2、密度为16 500株/hm2、单株留叶20片为宜. |

| Abstract: | The experiments were conducted to study the relationship between tobacco leaf quality and nitrogen application level in counties of Weining,Daozhen,Anlong,Weng'an and Dushan of Guizhou Province in 2001-2003.The results showed that tobacco yields could increase with the increase of organic fertilizer and N rates.High-grade tobacco leaves were observed in the N application of 90 kg /hm2.The results also indicated that with the plant population of 16 500 per acre and 20 leaves per plant,the N fertilizer rates of 60-90 kg /hm2 and 90-120 kg /hm2 was desirable in Weining of high altitude and other counties respectively. |
