为明确有机肥与无机肥的最佳配比,通过有机肥梯度对比试验,比较研究了有机肥与无机肥不同施用配比对烤烟‘K326’农艺性状、外观质量、内在化学成分、感官评吸及经济效益的影响。结果表明:在有机肥用量为30%和无机肥用量为70%时,能促进烟株的生长发育,农艺性状最好;烤后烟叶的叶片结构、油分及色度均有改善,烟叶的外观质量达到最优;烟叶的总糖和还原糖含量增加,总氮和烟碱含量有所降低,同时各项化学成分指标更趋于协调;增加了烟叶的香气质和香气量,减小了刺激性和杂气,改善烟叶吃味;中上等烟比例提高7.7%,均价提高8.9%,净产值提高9.1%。综合考虑有机肥投入产出效益,建议在生产中施用30%的有机肥和70%的无机肥,以提高烟叶工业可用性和烟农的种烟效益。
In order to clarify the best proportion of organic fertilizer and inorganic fertilizer, through organic fertilizer gradient contrast test, the effects of different application proportion of organic fertilizer and inorganic fertilizer on the agronomic characters, appearance quality, internal chemical composition, sensory evaluation of flue-cured tobacco ’K326’ And the impact of economic benefits. The results showed that when the amount of organic fertilizer was 30% and the amount of inorganic fertilizer was 70%, the growth and development of tobacco plants were promoted and the agronomic characters were the best. The leaf structure, oil content and chroma of tobacco leaves were improved after roasting, The quality reached the optimal; the total sugar and reducing sugar content of tobacco increased, total nitrogen and nicotine content decreased, at the same time the chemical composition of the indicators tend to be more coordinated; increase the aroma quality and aroma of tobacco, reducing irritation And miscellaneous gas to improve the tobacco taste; middle and upper smoke increased 7.7%, the average price increased 8.9%, net output increased 9.1%. Considering organic fertilizer input-output benefits, it is recommended to use 30% organic fertilizer and 70% inorganic fertilizer in the production to improve the industrial availability of tobacco leaf and the tobacco planting tobacco farmer’s benefit.
