摘　　要：美国是花生收获机械化最早也是技术最先进国家,花生生产与出口一直保持世界强国地位。为探明美国花生收获机械化高水平发展主要动因,发现可供借鉴的经验和教训,运用文献研究法、社会调查法、经验总结法和一般科学思维方法等,系统地回顾了美国20世纪40年代以来花生收获方式和机械化收获技术衍变历程,深入分析了两段收获方式的选择和农机农艺紧密融合过程及其在花生收获机械化发展中的关键作用。结合中国花生生产与机械化现状,提出了因地制宜确立各主产区适宜的花生收获方式和技术路线,建立区域性花生种植技术体系,处理好花生花生机械技术引进与研发的关系,加强花生收获机械关键技术、产地干燥技术和花生秸秆收获技术研发等建议。Peanut is a very important crop forfood and edible oil in the world. China is the largest peanut producer in total annual production accounted for about 40.26% and the second-largest in peanut planting area accounted for about 16.68% in the world. China, India and Nigeria, United States, Argentina and Brazil all are major important peanut exporters in the world. In the United States, the peanut area planted only accounted for about 2.46%, but total annual peanut production accounted for about 6.11% and export peanut accounted for 16.03% in 2016, which make the United States become a leading country of peanut production and exportation nation in the word. Based on comprehensively analysis, the main reasons why a country becomes strongest peanut production nation is that high level harvest mechanization plays an important role for peanut production. Harvesting is a key part in peanut production, it accounts for more than 50 percent labor employment of the whole process. However, in the USA, the application of peanut harvest mechanization was implemented in 1950＇s that dramatically changed peanut harvesting practices. The peanut harvest mechanization mode has two stages in USA. Two pieces of equipment developed in the late 1940＇s contributed to the major changes in harvesting practices in the USA, those include a peanut shaker-windrower and peanut combine. A peanut shaker-windrower was further advanced to Digger-Shaker-Inverter in the early 1970＇s, which can turn the plants upside down and place two rows together in a windrow to cure. The second piece of equipment is a peanut combine that picks up the peanuts plants from the windrow after they are dried to a safe moisture level, picks off the pods, and deposits the cleaned pods into bulk tanks. After combining, the peanuts are placed in a curing facility where low humidity air is forced through the peanuts to evaporate the excess moisture. With the advances of peanut harvest mechanization technology, the United States has been leading its peanut production wi
