| 摘 要： | 为研究膜下滴灌施肥技术对攀枝花烤烟烟叶产量和品质的影响,本试验以6种不同施肥技术,3次重复开展大田随机区组试验。结果表明：与常规施肥(T1)技术相比,膜下滴灌施肥技术可明显缓解攀枝花烟区生产中遭遇的前期干旱问题,促进烟株的生长发育,改善烟株的农艺性状。采用膜下滴灌施肥氮、磷施肥总量分别减少15 、18kg/hm2(T5)时对烤烟产量产值的影响不大。但同时减少氮磷钾肥施用量(T4)或氮、磷施肥总量分别减少23 、21kg/hm2(T6)时会造成较明显的减产减值效果。T2和T5处理烟叶中各项化学成分趋于协调平衡,更接近优质烟叶适宜含量范围。因此,综合考虑建议攀枝花烟区膜下滴灌施肥方案为：在常规施肥量基础上,钾肥用量不变,氮、磷施肥总量分别减少15、18 kg/hm2。

Drip Fertilization Under Plastic Film Affects Yield and Quality of Flue-cured Tobacco in Panzhihua |

| Abstract: | The study aims at the effect of drip fertilization under plastic film on yield and quality of flue-cured tobacco in Panzhihua, Sichuan Province. A field experiment of random blocks with six kinds of fertilization and three repeats was conducted. The results indicated that compared with conventional fertilization (T1), drip fertilization under plastic film could relieve the drought problem encountered in tobacco production of Panzhihua, and promote the growth and agricultural characteristics of tobacco plant. By adopting drip fertilization under plastic mulch, the cut of N and P fertilizer by 15 and 18 kg/hm2 (T5), respectively, will not cause the decrease of yield and output value. However, the simultaneous cut of N, P and K fertilizer(T4) or the reduction of N and P fertilizer by 23 and 21 kg/hm2(T6) will cause the reduction in yield and output value. By adopting the treatment T2 and T5, the content and ratio of chemical compositions of tobacco leaves are coordinated and closer to the appropriate one of high quality tobacco. Therefore, on the basis of the conventional application rate of fertilizers, the cut of N and P fertilizer by 15 and 18 kg/hm2 is the suitable scheme of drip fertilization under plastic film in Panzhihua. |
