    有機肥料定位還田對煙葉品質(zhì)及土壤性狀的影響

    The Effects of Applying Organic Fertilizers on the Leaf Quality of Flue-cured Tobacco and Soil Characteristics

    • 摘要: 通過5年田間定位試驗研究了有機肥料連續(xù)還田對煙葉產(chǎn)量,、質(zhì)量及土壤理化性狀的影響,。結(jié)果表明，煙田連續(xù)4年使用有機肥料,，土壤容重降低0.1 g/cm3,，土壤中放線菌、硝化細菌,、亞硝化細菌數(shù)量分別增加6.1倍,、12.2倍、11.5倍,；煙田連續(xù)5年使用有機肥料,，煙葉產(chǎn)量增加38.9%,，產(chǎn)值增加23.9%，煙葉化學成分更趨協(xié)調(diào),，煙葉感官評吸質(zhì)量得到明顯改善,，土壤有機質(zhì)含量提高0.26個百分點；有機肥料連續(xù)還田土壤,、煙葉中氯離子含量略有增加并穩(wěn)定在適宜范圍內(nèi),，煙葉能夠正常成熟。煙田長期使用有機肥料效果明顯,。

       

      Abstract: A five year field experiment was conducted to investigate the effects of returning organic fertilizers to field continuously on leaf quality of flue-cured tobacco and soil physical and chemical properties. The results showed that, after applying organic fertilizers for 4 years, soil bulk density decreased 0.1 g/cm3. The number of actinomycetes, nitrifier, and nitrosobacteria in soil increased 6.1, 12.1, and 11.5 times, respectively. After applying organic fertilizers for 5 years, the yield of tobacco leaf increased 38.9%, the value increased 23.9%, the leaf composition became more harmonized, the sense and smoking tests results improved remarkably, and the soil organic matter increased 0.26%. By returning organic fertilizers to field continuously, the Cl content of the soils and tobacco leaves increased slightly and then stabilized in the appropriate ranges, and tobacco leaves could mature normally. In conclusion, long term application of organic fertilizers have remarkable effects on tobacco production.
