我们与呼和浩特糖厂及内蒙农研所土肥系协作研究和示范的结果表明,以磷为主,磷氮肥料配合作种肥,对促进甜菜增产增糖,效果十分显著。增产幅度为10.3—34.7%,含糖率提高0.4—1.6%,产糖量增加22.5—32.5%,这项措施已在区内外推广应用。磷氮肥配合比例,在目前生产条件和肥料数量情况下,一般土壤每亩 The results of our collaborative research and demonstration with the Department of Soil Science and Technology, Hohhot Sugar Plant and Inner Mongolia Agricultural Research Institute have shown that phosphorus-based fertilizers and phosphorus-nitrogen fertilizers are effective in promoting sugar beet production. The yield increase is 10.3-34.7%, the sugar content increased by 0.4-1.6% and the sugar yield increased by 22.5-32.5%. This measure has been widely applied in and out of the region. Phosphorus and nitrogen fertilizer with the proportion of the current production conditions and the amount of fertilizer, the general soil per acre
