在甜菜营养生产期中,蔗糖在叶片中合成,但主要积累在块根中,收获后送至糖厂加工制得蔗糖。根颈是甜菜块根上叶柄着生的部位,收获时常将它全部或部分地切除,因为其中含有相对较多的化学杂质,包括K~+和N_a~+,它们不利于加工制糖。地上部分在国外常留在 In the sugar beet nutrition production period, sucrose is synthesized in the leaves, but mainly accumulated in the roots of the tubers, which is then sent to the sugar mill for sugar production after harvesting. The root of the root is the part of the beetroot rooted above the petiole. It is often harvested when it is harvested, because it contains relatively large amounts of chemical impurities, including K ~ + and N_a ~ +, which are detrimental to sugar processing. The aerial parts are often left abroad
