Abstract

Abstract: The foliar fertilizer was synthesized with the titanium-bearing blast furnace slag， potassium bisulfate， citric acid， urea and magnesium oxide as raw materials by melting and chelating methods. The field cultivation experiments of sweet corns were carried out in order to evaluate the effects of the foliar fertilizer on the growth， yield， characters and the SPAD value of nitrogen， magnesium， sugar and heavy metal in grains. The results showed that the foliar fertilizer contained nutritional elements such as nitrogen， sulfur， potassium， iron， titanium and magnesium. The application of the foliar fertilizer shortened the growing period of the sweet corn by 2 days， and also made the yield， plant heights， diameters of the stem and ears， grain number per panicle， weight of single spike， and the number of efficient panicles per plant， together with the SPAD value of chlorophyll in leaves， nitrogen and magnesium in grains significantly increase. However， there was no difference in the mass fraction of sugar， titanium， vanadium and chromium in the sweet corn. In addition， mass fractions of the heavy metal elements like vanadium and chromium in the sweet corn were below the maximum residue limit set by National Standards of China.

Key words: titanium-bearing blast furnace slag, foliar fertilizer, nutritional element, sweet corn, yield
