甜菜为高产作物,根系庞大,入土深广,需要从土壤中摄取大量营养物质才能满足地上茎叶生长,并将合成的有机物质(主要为蔗糖)运往地下块根中贮藏。甜菜需肥多、吸肥时间长、吸收营养全面,不但需要大量肥料,而且也要相应地吸收适量的微量营养。 Beet is a high-yielding crop with a large root system and deep soil. It needs a large amount of nutrients from the soil to meet the growth of shoots and leaves on the ground, and the synthetic organic matter (mainly sucrose) is transported to underground tubers for storage. Beet needs fat, long fat absorption, absorption of nutrients in a comprehensive, not only requires a lot of fertilizer, but also to absorb the appropriate amount of micronutrients.
