木薯(Manihot esculenta)广泛种植于热带非干旱地区,在发展中国家里,有5亿多人以此为主要食物来源。人们种植木薯主要是为了获取其根茎部分,而薯叶则通常被当作蔬菜来食用。薯根主要由碳水化合物所组成,而叶子却是蛋白质和维生素的极好资源。薯叶的产量主要取决于降雨量、种植密度和品种。此外,采摘叶子的次数对薯叶与薯根的总产量也产生直接影响。据研究,在木薯种下去四至五个月后,每月摘一次叶子可获得薯 Manihot esculenta is widely planted in tropical and arid regions, with more than 500 million people in developing countries as its main source of food. People grow cassava mainly to obtain parts of their rhizomes, while potato leaves are often eaten as vegetables. Roots are mainly composed of carbohydrates, while leaves are excellent sources of protein and vitamins. The yield of potato leaves depends mainly on rainfall, planting density and variety. In addition, the number of leaves picked also has a direct impact on the total yield of potato leaves and roots. According to the study, after four to five months of cassava farming, the leaves can be picked once a month
