再过14年人们跨入了21世纪。到那时,农业发展情况将怎样?就农作物的种植而言,在很大程度上与现在大致一样。但由于计算机技术、遗传改进、生长调节剂和水利资源的充分利用,农业将更加发展、更加进步。在过去的50年中,遗传改进每亩作物年产量增加了1.4蒲式耳,美国衣阿华大学的最近研究表明:人们没有理由不相信作物产量仍能继续提高,特别是遗传工程和作物育种在农业上的应用将使产量提高得更快。新杂交品种或本世纪末所种植的各种作物将更能抗庄稼疾病,籽苗将更加充满活力而更不易受外界环境的各种影响。农作物的抗生力
In another 14 years people entered the 21st century. By that time, what will happen to agricultural development? To a large extent, the cultivation of crops will be largely the same now. However, due to advances in computer technology, genetic improvement, growth regulators and water resources, agriculture will be more developed and more advanced. In the past 50 years, the annual genetic improvement yield per acre crop has increased by 1.4 bushels. Recent studies by the University of Iowa in the United States have shown that there is no reason not to believe that crop yields will continue to rise, especially in genetic engineering and crop breeding in agriculture On the application will increase the yield faster. New hybrids or crops planted at the end of this century will be more resistant to crop diseases and the seedlings will be more vibrant and less susceptible to various external influences.
