摘要
【目的】研究饼粕肥与烟草专用肥配施对烟叶生长发育及烟叶品质的影响,为打造郴州浓香型特色烟叶品牌和加快烟草专用基肥更新换代提供依据。【方法】以不同比例饼粕有机肥与烟草专用基肥作基肥配施,调查烟株不同生育时期相关农艺性状,并对与烟叶品质密切相关的几种化学成分进行分析。【结果】不同比例饼粕肥与烟草专用肥配施处理与CK相比,烟草株高可提高3.01%～5.84%,有效叶片数增加5.56%～20.39%,烟叶糖碱比更趋近于10±1,氮碱比更趋近于1±0.1。【结论】750kg/ha的烟草专用基肥与292kg/ha饼粕肥配施对改善烟株农艺性状、提高烟叶品质指标效果最好。
[Objective]To build an enriched-flavor special tobacco brand in Chenzhou and develop fertilizers used in tobacco cultivation, the effects of cake fertilizers in combination with special tobacco fertilizer on the growth and development as well as the quality of tobacco leaves were investigated. [Method]Different ratios of cake organic fertilizer and special fertilizer were applied as base fertilizer and several agronomic traits and leaf quality determining chemical components were measured and analyzed at different growing stages. [Result]Compared to control, all treatments resulted in 3.01-5.84% increase in plant height and enhancement in effective leaf number from 5.56-20.39%. Further, the sugar/nitrogen ratio in leaves was closer to 10±1, and nitrogen/nicotine ratio in leaves was closer to 1±0.1. [Conclusion]The combined treatment （T2） of special tobacco base fertilizer （750 kg/ha） and cake organic fertilizer （292 kg/ha） proved to be the best fertilizer pertinent to the improvement of agronomic traits and leaf quality of tobacco.
