为了研究增施有机肥对烤烟上部烟叶产质量的影响,以K326为供试材料,进行了施肥试验。结果表明:在施纯氮、P2O5和K2O比例相同的情况下,增加有机肥的用量、降低复合肥的用量对烟叶生育期,打顶15天后烤烟主要农艺性状,以及上等烟和上中等烟叶比例等的影响无显著差异,但能够显著提高烟叶等级,改善烟叶品质,提高烟叶的均价,以弥补其在烟叶产量上的不足。建议烟叶生产中在使用复合肥保障产量的同时,增加腐熟的牛羊粪、饼枯等有机肥的施用量,以提高烟叶的品质。
In order to study the effects of organic manure on the yield and quality of tobacco leaves in the upper part of flue-cured tobacco, K326 was used to test the fertilization. The results showed that under the same proportion of pure nitrogen, P2O5 and K2O, the main agronomic traits of flue-cured tobacco increased with the increase of organic manure and the dosage of compound fertilizer, Proportion and other effects were not significantly different, but can significantly improve the grade of tobacco, improve the quality of tobacco, raise the average price of tobacco to make up for its lack of yield on the leaf. Proposed tobacco production in the use of compound fertilizer to protect the yield at the same time increase the maturity of cattle and sheep dung, cakes and other organic fertilizer application rate in order to improve the quality of tobacco.
