Abstract: Compound fertilizer was synthesized with titanium-bearing blast furnace slag as a major raw material by heating method. Its solubility was enhanced so that the nutritional elements transform into the form which can be absorbed easily by plants. The effects of fertilizer on the character, yield, sugar content and nutritional elements of sugar beet were investigated by cultivation experiment. The results show that the dissolution rates of titanium, magnesium and iron from slag are 84%, 88% and 75% respectively. The fertilizer contains such nutritional elements as nitrogen, silica, sulfur, calcium, iron, titanium and magnesium, which can all be absorbed effectively by nurture plants. The fertilizer can increase significantly the plant height, root length, leaf weight and the chlorophyll content of sugar beet. The yield of sugar beet is increased by 22.03%, and its sugar content is increased by 15.57%, leading to a sugar yield increase of 41.03%. All these indicate that the fertilizer can promote the growth of sugar beet.
