不同氮素形态烤烟专用基肥与追肥配合施用对不同品种烟叶产质量的影响

The Effects on Different Varieties Tobacco Yield and Quality by Using Different Forms of Specific Nitrogen Basal and Top Dressing Fertilizer

采用正交试验设计,通过田间小区试验,对不同硝态氮含量基肥、不同追肥类型及不同基、追肥比例与不同烤烟品种的研究,结果表明,在9个处理中,处理A1B1C1D1表现最佳,在产、质量方面均居于首位。从品种上来看,云烟85品种底肥宜使用硝态氮含量占50%,铵态氮含量占50%的复合肥,云烟87品种底肥宜使用硝态氮含量占30%,铵态氮含量占70%的复合肥,K326品种底肥宜使用硝态氮含量占40%,铵态氮含量占60%的复合肥,追肥均以使用硝酸钾为宜。

Using orthogonal experimental design to the field experiment, it was studied on different basal nitrate content, different type of top dressing, different proportion of base dressing and different varieties of flue-cured tobacco. The results showed that A1B1C1D1 was the best and its yield and quality was at the top in the nine processing. Viewing from the varieties, the base fertilizer used for Yunyan85 should be accounted for 50% nitrate content and 50% ammonium nitrogen content,Yunyan 87 should be accounted for 30% nitrate content and 70% ammonium nitrogen content, K326 should be accounted for 40% nitrate content and 60% ammonium nitrogen content. The top dressing was appropriated for using potassium nitrate fertilizer.
