摘要/Abstract

摘要： 以含钛高炉渣、硫酸氢钾、柠檬酸、尿素和氧化镁为原料，采用熔融和螯合法制备叶面肥，并通过大田栽培实验研究了该叶面肥对甜玉米生长状况、产量、性状及籽粒的氮、镁、糖和重金属质量分数的影响.结果表明，该叶面肥含有植物营养元素氮、硫、钾、镁、铁和钛；该叶面肥的施用使甜玉米生育期缩短2d；产量、株高、茎粗、穗粗、穗粒数、单穗重、单株有效穗数、叶片中叶绿素的SPAD值、籽粒中氮和镁的质量分数明显增加，籽粒中糖、钛、钒和铬的质量分数无明显变化，且重金属元素钒和铬的质量分数符合国家标准.

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
