比利时的甜菜播种面积为10～15万公顷。甜菜种植的集中程度为世界第一,单位面积产糖量也最高;每公顷为6.5～7.2吨。这是因为他们有很高的耕作水平,大量的施肥和高质量的良种等条件保证。化肥的施用量按计划的产量来确定。例如,要获得每公顷50吨的产量,则每公顷施有效成分 N—200～250公斤,P—75～100公斤,K—250～400公斤。根据近三年比利时六个点的品种试验资料,块根产量为59.7～68.7吨/公顷。含糖 Belgian sugar beet sown area of ​​10 to 150,000 hectares. The concentration of beet cultivation is the highest in the world and the highest yield of sugar per unit area is 6.5-7.2 tons per hectare. This is because they have a high level of farming, a lot of fertilization and high-quality seeds and other conditions guarantee. Fertilizer application rate according to the planned output to determine. For example, to obtain a yield of 50 tons per hectare, apply N-200 to 250 kilograms, P-75 to 100 kilograms, and K-250 to 400 kilograms per hectare of active ingredient. According to the test data of six varieties in Belgium in recent three years, the yield of tuberous roots is 59.7-68.7 tons / ha. Sugary
