  摘要 [目的]為了探討不同類型有機肥與無機肥配施對攀枝花煙區(qū)主栽品種云煙85農藝性狀、經濟性狀及品質的影響。[方法]選取農家肥、油枯、氨基酸有機肥、海藻有機肥4種有機肥與無機肥合理配施,開展田間試驗。[結果]不同種類有機肥與無機肥配施對烤煙株高、莖圍、葉面積系數等農藝性狀的影響明顯,對節(jié)距的影響不明顯,氨基酸有機肥處理效果最優(yōu),海藻有機肥處理效果較優(yōu)。施用不同類型的有機肥對烤煙各經濟性狀指標有不同程度的提高,其中,氨基酸有機肥處理產量、產值最高,分別達到3 062.25 kg/hm<sup>2</sup>、58 446.45元/hm<sup>2</sup>,農家肥處理次之;中上等煙葉比例以油枯處理最高,氨基酸有機肥處理次之。各處理煙葉主要化學品質差異明顯,氨基酸有機肥處理的各項主要化學品質之間協調性最佳。[結論]有機無機肥配施對提高烤煙農藝性狀、經濟性狀和改善煙葉化學品質具有明顯作用,尤其氨基酸有機肥與無機肥的配合施用效果最優(yōu)。

  Abstract [Objective] The research aimed to discussion the effects of combined application of the organic and chemical fertilizers on agronomic characters, economic characters and quality of Yunyan85. [Method] According to current situation of Panzhihua tobacco fertilization, manure, oil cake, amino acid organic fertilizer and seaweed organic fertilizer were combined with inorganic fertilizer reasonably.[Result] The effects of different types of organic fertilizer and chemical fertilizer on fluecured tobacco plant height, stem girth and leaf area index were obvious. There was no significant effect on the pitch. The effect of amino acid organic fertilizer treatment was the best of all, followed by seaweed organic fertilizer treatment. Applying different kinds of organic fertilizer on fluecured tobacco could improve the yield, output value, and the proportion of fine tobacco. The yield and output value of the amino acid organic fertilizer treatment was the highest, followed by manure organic fertilizer. The main chemical quality of each treatment was significantly different, and the coordination among the major chemicals of the amino acid organic fertilizer treatment was the best. [Conclusion]Combined application of organic and inorganic fertilizers could improve the fluecured tobacco agronomic traits, economic traits and the quality of tobacco leaf chemistry significantly, especially combined application of amino organic fertilizer and inorganic fertilizer optimal.
