磷、钾在甜菜生育活动过程中起着重要作用。根据苏北平原沙碱土的特点,我们研究用磷酸二氢钾复合肥料来提高甜菜产量,改善其品质,以期进一步发展苏北甜菜生产。本试验通过不同时期,不同浓度施用磷酸二氢钾对甜菜的效果,了解其茎叶、块根的生长和糖分积累的规律,以及产量影响。为合理施肥,获得大面积丰产提供科学依据。 Phosphorus and potassium play an important role in the process of sugar beet fertility. According to the characteristics of the sandy soils in the northern Jiangsu plain, we studied the use of potassium dihydrogen phosphate fertilizer to improve sugar beet yield and improve its quality, in order to further develop the production of sugar beet in northern Jiangsu. In this experiment, the effects of potassium dihydrogen phosphate on sugar beet in different periods and different concentrations were studied to understand the rules of stem and leaf, root growth and sugar accumulation and the effects of yield. To provide a scientific basis for fertilization, large-area yield.
