有机-无机复混肥对烤烟生长及产质量的影响

Effect of Organic-inorganic Compound Fertilizer on Growth,Yield and Quality of Flue-cured Tobacco

研究不同类型有机-无机复混肥对烤烟产质量的影响,筛选出适合云南昭通市烤烟生产上施用效果好的肥料品种及最佳施肥量,试验结果表明：施用有机-无机复混肥能促进烟株早生快发,叶片开片好,进入旺长期快,以＂珍发＂牌有机-无机复混肥田间表现较好,施用有机-无机复混肥烟叶产量提高0.79%～7.60%,产值提高4.48%~10.58%。以50%烟草专用肥＋50%有机-无机复混肥施肥处理的各项指标较好,其中以50%烟草专用肥＋50%＂珍发＂牌有机-无机复混肥处理最佳,产量、产值、均价及上等烟比例分别为2 989.35 kg/hm2、40 007.85元/hm2、13.39元/kg、44.88%。施用有机-无机复混肥能大幅提高烟叶的经济效益。

The effect of different types of organic-inorganic compound fertilizer on yield and quality of flue-cured tobacco was studied,in order to screen the best fertilizer varieties and the optimum amount of fertilization for tobacco production of Yunnan Zhaotong City.The results showed that： the application of organic-inorganic fertilizer could promote tobacco plant＇s growth and development,promote the leaves＇ growth,enter the vigorous growing period fast.The ＇Zhenfa＇ organic-inorganic fertilizer was better in the field performance,yield increased by 0.79%~7.60%,output value increased by 4.48%~10.58% using the organic-inorganic compound fertilizer.Fertilier amount with 50% tobacco special fertilizer and 50% organic-inorganic fertilizer showed good performance in each index.The yield,output value,price and the proportion of high-quality leaves reached respectively 2 989.35 kg/hm2,40 007.85 yuan/hm2,13.39 yuan/kg,44.88% using ＇Zhenfa＇ fertilizer.Application of organic-inorganic compound fertilizer could greatly improve the economic benefit of tobacco.
