拉丁美洲的一些科学工作者,正在对古印卡人曾经种植过的一种作物——昆诺阿藜(chenopodium quinoa Willd.)进行多方面的研究。昆诺阿藜是藜属植物,通常种植在海拔2,000—4,000米的高地,耐严寒,能在土壤贫瘠、年雨量300—400毫米的干旱条件下旺盛生长。它的种子蛋白质含量平均达14％左右,赖氨酸占6％,这就使它的营养价值超过大多数粮食作物。它还含有维生素C,以及由硫胺素、核黄素和菸酸组成的维生素B复体。正因为如此,秘鲁、玻利维亚和智利都很重视这种作物。玻利维亚甚至通过一项法令,要求在商用面
Some scientific workers in Latin America are conducting multi-faceted research on the chenopodium quinoa Willd., a crop that was once planted by ancient Incas. Aunt Quinaud is a member of the genus Polygonum, and is usually planted on highlands at altitudes of 2,000 to 4,000 meters above sea level. It is extremely tolerant to cold and can thrive under conditions of poor soil and annual rainfall of 300-400 mm. Its seed protein content averages about 14%, and lysine accounts for 6%, which makes it more nutritious than most food crops. It also contains vitamin C, as well as vitamin B complexes consisting of thiamine, riboflavin, and niacin. Because of this, Peru, Bolivia and Chile attach great importance to this crop. Bolivia even passed a decree requiring commercial
