摘 要:为探究雪茄烟楚雪10号品种的适宜氮、磷、钾肥用量,采用田间“3414”试验,研究不同氮、磷、钾肥料处理对雪茄烟楚雪10号农艺性状及产量的影响。结果表明:施肥可不同程度提高雪茄烟株高、茎粗、叶长、叶宽、有效叶片数等农艺性状,且雪茄烟对氮的依赖性最强,施氮能显著提高雪茄烟单位面积产量,而磷、钾对雪茄烟产量影响不明显;氮、磷、钾对雪茄烟产量的影响有互作效应,低磷、中钾水平利于氮肥效果的发挥,中氮、低钾水平利于磷肥效果的发挥,中磷、低氮水平利于钾肥效果的发挥;根据产量和农艺性状等得出最大产量下的施肥量为纯N 180 kg/hm^(2)、P2O560 kg/hm^(2)、K2O 360 kg/hm^(2)。说明适当控制氮肥和钾肥施用量,增加磷肥施用量,同时将三者进行合理配比,对提高雪茄烟产量有重要意义。In order to explore the suitable amount of nitrogen,phosphorus and potassium fertilizer for cigar Chuxue 10,the field"3414"experiment was conducted to study the effects of different nitrogen,phosphorus and potassium fertilizer treatments on the basic agronomic characters and yield of Chuxue 10.The results showed that fertilization could promote the agronomic characters of cigar in varying degrees,such as plant height,stem diameter,leaf length,leaf width and the number of effective leaf.The cigar had the strongest dependence on nitrogen,and nitrogen application could significantly increase cigar yield per unit area,while phosphorus and potassium had no significant effect on cigar yield.The effects of nitrogen,phosphorus,and potassium on cigar yield had an interactive effect.Low phosphorus and medium potassium levels were conducive to the effectiveness of nitrogen fertilizer.Medium nitrogen and low potassium levels were conducive to the effectiveness of phosphorus fertilizer.Medium phosphorus and low nitrogen levels were conducive to the effectiveness of potassium fertilizer.According to the yield and agronomic characters,the fertilizer application amount under the maximum yield was N 180 kg/hm^(2),P2O560 kg/hm^(2),and K2O 360 kg/hm^(2).It indicated that proper control of nitrogen and potassium fertilizer application,increasing phosphorus application,and reasonable matching of the three were of great significance for improving cigar yield.
