花生,又名落花生,以其开花落地结实而得名。在人类琳琅满目的栽培作物中,这种地上开花,入地结果的庄稼,是绝无仅有的。花生起源于南美洲热带亚热带地区,这是世界公认的,似乎无可非议。考古学家在沿秘鲁海岸狭长地带的史前遗址中,发现大量的古代印弟安人遗下的花生实物。在南美,从巴西北部、东北部至南纬35度,从安弟斯山麓到大西洋海岸,不论在草原牧场或在林间空地都能见到单独或成群分布的野生花生。 Peanuts, also known as peanuts, are named after their flowering floorings. Among the numerous cultivated crops in mankind, this kind of crop that blossom on the ground and land the result is unique. Peanut originated in tropical and subtropical South American regions, which is universally acknowledged and seems beyond reproach. Archaeologists found a large number of peanuts survived by ancient Indians in prehistoric sites along the Peruvian coast. In South America, from northern Brazil, northeast to 35 degrees south latitude, from Andes to the coast of the Atlantic Ocean, wild peanuts can be found individually or in groups, both in pasturelands and in open spaces.
