除了品种间差异之外,甜菜的含糖率与栽培条件有密切关系。许多农业措施,如留苗密度、施肥、灌水、病虫防治等对甜菜含糖率高低有显著影响。1.适当增加密度。密度增加,相对缩小了单株的营养面积。甜菜糖分含量与根重呈负相关,个体营养面积越小,根重量越低,含糖率越高。反之,营养面积越大,单株根重量越高,含糖率就越低。因此,应根据当地的土壤、气候条件以及肥水等状况,因地制宜地加大种植密度。 In addition to the differences between varieties, the sugar content of sugar beet is closely related to the cultivation conditions. Many agricultural measures, such as the density of seedlings, fertilization, irrigation, pest control and other beet have a significant impact on the sugar content. 1. Appropriate to increase the density. Increased density, relative to narrow the nutritional area of ​​the plant. Beet sugar content and root weight were negatively correlated, the smaller the individual nutrient area, the lower the root weight, the higher the sugar content. Conversely, the larger the nutrient area, the higher the root weight per plant, the lower the sugar content. Therefore, according to the local soil, climatic conditions and fertilizer and other conditions, according to local conditions to increase planting density.
