摘　　要：采用动态分析的方法,分析了北方水稻生产的现状。结果表明,1961年以来,北方水稻栽培面积、单产和总产都呈增长趋势。稻米品质同市场需求比有差距,高产优质品种较少,稻米食味值需要提高。应该选用优质高产品种,并采用营养土保温旱育苗、合理稀植、节水灌溉、平衡施肥、综合防治病虫草害等措施组成的配套栽培技术,来增加水稻产量,改善稻米品质。The north rice production status was studied using dynamic analysis method. The result indicated that the planting area, grain yield per unit area and output of rice in northern China were all increasing from 1961 to 2005, but the quality of rice was lower than that of consumers＂ demand. The eating quality needs improving. In high-yielding and fine quality rice production, multiple techniques composed of high-yielding rice varieties selection, sparse sowing and transplanting, nutrient equilibrium fertilizing, water-saving irrigation, comprehensive plant diseases, insect pests and paddy weeds control should be applied.
