对北疆甜菜地块不同土壤养分和前茬进行养分分析测定试验，结果表明：不同土壤和前茬中养分发生明显变化，使含糖率下降１０５７～３８ 个百分点，特别是速效磷和速效锌含量较对照地块下降１８５４～１６３４ ｍ ｇ／ｋｇ 和１６０５～１３３８ｍ ｇ／ｋｇ。在甜菜块根分化形成期和块根增长期补充速效磷和速效锌将会促进糖分转化，提高含糖率和防治腐烂病发生。 The results showed that the nutrients in different soils and the previous crop changed obviously, the sugar content decreased 1057 ~ 38 percentage points, especially the quick effect Phosphorus and available Zn decreased 1854 ~ 1634 m g / kg and 1605 ~ 1338 m g / kg compared with the control plots. Supplementation of available phosphorus and quick-acting zinc in rooting and rooting stage of beet root will promote sugar conversion, increase sugar content and prevent rot disease.
