甜菜（糖萝卜）的叶一般都被用作动物饲料，或被作为废物抛弃。最近美国塔斯基吉大学的科学家指出，甜菜的叶可用作蔬菜。科学家们利用营养膜技术，将甜菜种植在半浓度的Hoagland营养液中，以检测甜菜的生物学产量和营养品质。结果表明，6个月后甜菜的贮藏很重和叶重分别为493 Beets (sugar beet) leaves are generally used as animal feed, or abandoned as waste. Recently, scientists at Tuskegee University in the United States pointed out that the leaves of beet can be used as vegetables. Using nutrient membrane technology, scientists planted beets in a half-strength Hoagland nutrient solution to test their biological yield and nutritional quality. The results showed that, after 6 months, the sugar beet was stored at a weight of 493 leaf weight
