摘　　要：为探索适宜皖南地区烟稻轮作的粳稻新品种,进一步明确不同施氮量下优质光身稻嘉58的种植表现,在大田下研究了不同施氮量(100.0kg·hm-2:LN、200.0kg·hm-2:MN、300.0kg·hm-2:HN)对嘉58的影响。结果表明,嘉58比较适合中等氮素,可以最大程度地发挥其叶片的光合功能,从而有利于大库的形成及产量构成。The objective of this study was to exploring Southern tobacco japonica rice about new varieties of crop rota-tion,to further clarify planting performance about“Jia 58”under different nitrogen fertilization in southern Anhui. Ef-fects of different nitrogen fertilization on＂Jia 58＂were studied（100.0 kg·hm-2：LN,200.0 kg·hm-2：MN,300.0 kg·hm-2：HN）in the field. The results showed Jia 58 is more suitable for moderate nitrogen,can maximize their photosynthet-ic function of the blade,which is conducive to the formation and production of large libraries constitute.
