烤烟栽培保水抗旱技术研究

Application of Water Conservation Technique in Cultivation of Flue-cured Tobacco

为了研究不同栽培保水措施对烤烟水分利用效率以及对烟叶产质量的影响程度,根据烤烟生育期内烟地畦面进行施用保水剂、施用秸秆、秸秆覆盖、地膜覆盖和对照等保水处理试验对比,分析了不同保水抗旱栽培措施对土壤含水率、农艺性状和产量产值的影响。结果表明,施用秸秆能很好地保水抗旱,对提高烟叶的总产量,提升中上等烟比例,增加产值等大有好处。

Four water conservation patterns of water-keeping agent, applying straw, mulch by straw and mulch with plastic film were tested in cultivation of flue-cured tobacco to study the effects of different water conservation patterns on soil water content and agronomic characters, yield and output value of flue-cured tobacco. The results showed that applying straw could raise soil water-holding capacity, improve tobacco yield and increase its output value by raising proportion of tobacco leaves with middle and first rank.
