美国是资本主义世界农业高度发达的国家。战后,美国农业生产已经实现了机械化、电气化和化学化,并且广泛地应用现代科学技术的成果,使得农业的单位产品率和劳动生产率都具有很先进的水平,一些重要农产品的产量和出口量均占资本主义世界的第一位。美国农业生产,达到目前的现代化水平,经历了将近一个世纪的发展过程。早在十九世纪后期,美国农业就随着资本主义生产关系的确立以及科学技术和工业生产的进展,开始走上资本主义大生产的道路。但是二十世纪初,美国农业生产基本上还是粗放经营,当时农业的技术水平远远落后于工业。到了第一次世界大战期间,由于国内外对农产品需求的增加,扩大耕地面积又缺乏劳动力,于是大农场尽力采用农业机器,降低生产成本,增强自己的竞争能力,以便获取更多的利润。1920年
The United States is a highly developed country in the capitalist world. After the war, the agricultural production in the United States has achieved mechanization, electrification and chemicalization, and the results of modern science and technology have been extensively applied. As a result, both the unit product rate and the labor productivity rate in agriculture are very advanced. The output and export volume of some important agricultural products All account for the first place in the capitalist world. The U.S. agricultural production has reached the current level of modernization and has undergone nearly a century of development. As early as the late nineteenth century, American agriculture began to embark on the path of capitalist mass production with the establishment of the capitalist relations of production and the progress of science, technology and industrial production. However, at the beginning of the 20th century, the agricultural production in the United States was still largely operated in a rough manner. At that time, the technical level of agriculture lagged far behind that of industry. During the First World War, due to the increasing demand for agricultural products both at home and abroad, there was a lack of labor to expand the cultivated area. Therefore, the large farms tried their best to use agricultural machinery to reduce production costs and enhance their competitiveness in order to obtain more profits. 1920 years
