摘要
为了提高香料烟的产量、产值和品质,采用田间小区试验研究了有机氮部分替代无机氮(取代比例分别为0、25%、50%)对香料烟产值及品质的影响。结果表明,有机氮取代部分无机氮对烤烟的产量、产值、上等烟比例和化学成分协调程度及矿质营养元素含量有很大的影响。其中,产量、产值和上等烟比例以有机氮取代50%无机氮处理最高,分别达到2 212.00kg/hm2、53 362.00元/hm2和70.22%。有机氮部分取代无机氮对香料烟叶片中化学成分、矿质元素的影响比较复杂,不同部位叶片以及不同化学成分的响应不同,但总体表现为有机氮取代无机氮改善了烤烟化学成分的协调程度,促进了有益矿质元素的积累。总之,对浙江省绍兴香料烟烟区来说,在施氮水平为105kg/hm2情况下,有机氮取代50%的无机氮时香料烟的经济产量、产值和烟叶品质较好。
In order to improve quality,yield and product value of oriental tobacco,a field plot experiment was conducted in Shaoxing,Zhejiang province,China,to investigate the effect of combined use of organic and inorganic nitrogen fertilizer on yield,economic value and quality of oriental tobacco.The results indicated that the ratio of organic nitrogen and inorganic nitrogen affected the yield,economic value,chemical constituent and mineral element.In this study,yield,economic value and fine tobacco ratio in the treatment of 50% ratio of organic nitrogen,achieved 2 212.00 kg/ha,53 362.00 yuan/ha and 70.22% respectively.However,the change of chemical constituents and mineral elements differed according to the tobacco leaf position and element types.As a whole,the 1∶1 ratio of organic nitrogen and inorganic nitrogen was the best fertilization among all the treatments for the oriental tobacco in Shaoxing of Zhejiang.
