不同有机肥及施肥量对初烤烟产质量的影响

为探讨正安烟区不同有机肥的合理施用量,将自制有机肥和商品有机肥各设300、600、900 kg/hm2 3个处理,对烤后烟叶经济性状、化学成分、香气成分、感官质量进行分析,比较不同施肥处理对烤烟产质量的影响.结果表明,自制有机肥和商品有机肥施肥量600 kg/hm2,烟叶经济性状最好;自制有机肥施肥量300～600 kg/hm2,商品有机肥施肥量600 kg/hm2,感官质量较好;自制有机肥和商品有机肥施肥量900 kg/hm2,化学成分较适宜.综合考虑两种有机肥对初烤烟主要性状的影响,兼顾有机肥施用成本,自制有机肥和商品有机肥施肥量以600 kg/hm2较合适.

Effect of different organic fertilizers and fertilization on flue-cured tobacco yield and quality

To explore the rational application of different organic fertilizer in zhengan tobacco-growing area, three fertilization treatments of each 300kg/hm2,600 kg/hm2 and 900kg/hm2 were set up by homemade and commodity organic fertilizer. Tobacco economic characters, chemical composition, aroma components and smoking quality were analyzed. The effect of flue-cured tobacco yield and quality by different fertilizer treatment was compared. The result showed that tobacco best economic characters were rate 600 kg/hm2 of Homemade and commodity organic fertilizer application. The better smoking quality was rate 300~600 kg/hm2 of homemade organic fertilizer application, or rate 600 kg/hm2 of commodity organic fertilizer application. The more appropriate chemical composition was rate 900 kg/hm2 of Homemade and commodity organic fertilizer application. The effect of flue-cured tobacco main characters by two kinds of organic fertilizer and the influence of both organic manure application cost were considered, homemade and commodity organic fertilizer with 600 kg/hm2 was more appropriate.
