摘要: [目的] 促进攀枝花烟区烤烟平衡施肥和新品种的推广应用。[方法] 在攀枝花烟区,以云烟97为供试材料,采用二次正交旋转设计,通过田间试验进行烤烟稳产增收的氮磷钾施肥优化研究。[结果] 氮磷钾肥都是影响云烟97产量的重要因素,氮磷钾肥用量整体水平提高,对增加云烟97的产值有明显的效应。增施氮肥能一定程度提高烤烟产量,过量则会降低产值;在一定范围内增施磷钾肥,有利于平衡协调烤烟产量和产值。[结论] 结合攀枝花烟区云烟97生产实际,确定最佳施肥方案为每667m2施入N 6kg,P2O5 7kg,K2O 25kg,能将产量稳定在175kg/667m2以上,产值增加到3500元/667m2以上。

Abstract: [Objective] In order to promote the application of balanced fertilization on tobacco and popularize the new varieties tobacco in Panzhihua area. [Method] Yunyan 97 was selected as the experiment materials, and the quadratic regressive orthogonal revolving design experiment was used to gain the optimum application ratio of NPK fertilizer for stable yield and output of Yunyan 97 in Panzhihua tobacco area. [Results] The results showed that the change of application ratio of NPK fertilizer had significant effect on the yield and output of Yunyan 97. With the rising of nitrogen dosage, the yield of Yunyan 97 was raised in a certain range, while excessive use of nitrogen would reduce the output. With the use of phosphorus and potassium fertilizers could balance the yield and output of Yunyan 97 within a certain range. [Conclusion] Considering the realities of Panzhihua tobacco area, the best ratio of fertilizers application for Yunyan 97 was N 6 kg/667 m2, P2O5 7 kg/667 m2, K2O 25 kg/667 m2, which can obtain the stable yield of 175 kg/667 m2 and the output can reach to 3 500 yuan/667 m2.
