密集烤房低温慢烤对烤烟经济效益的影响

Effects of Bulk Curing Barn Soft Temperature and Slow Curing Speed on Economic Benefit of Flue-cured Tobacco

[目的]研究密集烤房低温慢烤技术对烟叶的外观质量和经济效益的影响,为烟叶产区提供更科学的新烘烤技术。[方法]以"三段六步式"烘烤工艺为对照,研究了低温慢烤"新三段六步式"烘烤工艺烤后烟叶的外观质量、等级结构和经济效益。[结果]试验表明,与对照相比,低温慢烤新烘烤工艺烘烤的烟叶成熟度提高,油分增加,橘黄烟比例提高了21.54个百分点;上等烟比例增加了18.37个百分点,其中C2F烟叶的比例大幅增加,提高了23.73个百分点,相同等级相比,达到了极显著水平(α=0.01);每炕干烟(550 kg/炕)烟农增加净收益可达654元。[结论]低温慢烤"新三段六步式"烘烤工艺具有较强的实用价值,可在大部分烟叶产区推广使用。

[Objective] To study effects of bulk curing barn soft temperature and slow curing speed on appearance quality and economic benefit of tobacco leaf,and provide a more scientific curing technology for tobacco producing area.[Method] With ＂three stages of six steps＂ curing technique as the control,the appearance quality,grade structure and economic benefit of tobacco leaf after curing by soft temperature and slow curing speed were studied.[Result] The results showed that compared with the control,soft temperature and slow curing speed can improve tobacco leaf maturity degree and oil.The proportion of the orange leaves increased by 21.54 percent,and the superior leaf increased by 18.3 percent,among of them,grade C2F increased by 23.73 percent at the same level and the difference between them is extremely significant （α =0.01）.An extra profit increased 1.19 yuan per kilogram weight of cured leaf for tobacco grower compared with ＂three stages of six steps＂ curing method.[Conclusion] Soft temperature and slow curing speed technique has a strong practical value,which can be applied in most area of tobacco growing area.
