摘要: 探討不同氮磷鉀施用量對(duì)烤煙紅花大金元產(chǎn)量和品質(zhì)的影響,，為涼山煙區(qū)紅花大金元的進(jìn)一步推廣示范提供科學(xué)依據(jù),。試驗(yàn)設(shè)N1（60 kg/hm ）、N2（82.5 kg/hm ）,、N3（105 kg/hm ）3 個(gè)處理水平,，采用正交L9（3 ）設(shè)計(jì)，田間調(diào)查了各處理煙葉的農(nóng)藝性狀、主要經(jīng)濟(jì)性狀和質(zhì)量,。結(jié)果表明,，各處理的產(chǎn)量、產(chǎn)值,、均價(jià),、上等煙比例和上中等煙比例均有顯著差異，處理N（82.5）P（105）K（210）的經(jīng)濟(jì)性狀較好,，煙葉化學(xué)成分較適宜,，煙葉評(píng)吸最好。涼山煙區(qū)土壤中等肥力下紅花大金元的氮磷鉀最佳施用量為N: P: K=82.5: 105: 210,。Abstract: The objective of this study is to investigate the effects of N, P, K rates on yield and quality of flue-cured tobacco Honghuadajinyuan and to provide a scientific basis for further extension of Honghuadajinyuan in Liangshan. An orthogonal L9（3 ） design with three N rates was employed for the field experiment. Agronomic attributes, major economical characters, yield, and quality of tobacco Honghuadajinyuan were measured. The results showed that significant difference existed between various treatments for yield, value, average price, ratio of high-quality leaf,，ratio of high-middle-quality leaf. The tobacco leaves of treatment N(82.5)P(105)K(210) had superior economic characters, chemical composition, and the highest sensory evaluation value. Applying NPK at this rate could get optimum effect for Honghuadajinyuan under medium soil fertility in the tobacco region of Liangshan.
