不同肥料配施对烤烟生长发育及产质量的影响

摘要

通过开展田间试验,研究无机肥、有机肥及农家肥配施对烤烟生长发育及产质量的影响.结果表明,无机肥、有机肥及农家肥配施对提升烟叶质量效果好于单一施用无机肥;同时不同肥料配比对烟叶产值的影响也不相同,专用肥(公顷施纯氮105 kg)+菜饼(公顷施150 kg)+农家肥(公顷施7.5 t)的总体表现最佳.这可作为重庆烟区打造山地特色烟叶的施肥参考依据.%Field experiments were conducted to study the effects of inorganic fertilizer,organic manure and farmyard manure on growth and output value of Flue-cured tobacco.The results showed that combined application of the inorganic fertilizer,organic fertilizer and manure fertilizer to improve the quality of tobacco was better than the single application of inorganic fertilizer.At the same time,the effects of different fertilizer proportion on tobacco production was not the same,the best overall performance was the treatment of special fertilizer(hectare of pure nitrogen 105 kg) + vegetable cake(150 kg/hm2) + farmyard manure (7.5 t/hm2).This can be used as reference for fertilization in Chongqing tobacco area building mountain characteristic tobacco leaf.
