【摘要】 分析了近年来吉林省水稻生产的现状,稻作科技不断进步,水稻产量逐年提高,从20世纪60年代总产56.9万t、单产4005kg·hm-2,到2011年总产623.5万t、单产9019kg·hm-2,但同时水稻生产面临现实单产不同程度的下降、自然灾害严重、技术集成度不高和互补性不强等问题,制约了水稻产量提高和水稻生产可持续发展。针对上述问题,分析了从单产、品种、区域优势等方面挖掘增产潜力的措施,并讨论提高水稻产量的策略。更多还原

【Abstract】 We analyzed rice production status in Jilin Province in in recent years.With the inceasing progresses of science and technology in the rice cultivation the rice yield has increased year by year.The total out put was 263500 tons,per unit area yield was 4005kg·hm-2 during 1960s,while the total yield was 656000 tons,per unit area yield was 9019kg·hm-2 in 2011,at the same time rice production faced with problems of area reduce,yield decrease in different degree,serious natural calamity,much lower degree of integration and complementarity in technology which restricted the rice yield and the sustainable development of rice production.To deal with the above problems the measures were proposed for developing potentialities of yield in aspects of area yield,variety,regional advantage,and the strategy of improving the yield of rice.更多还原
