A field experiment was conducted to study the effects of Zinc fertilizer on corn growth and yield on the light salinized soil of Datong basin. The results showed that basal dressing of zinc fertilizer had the best effect on corn growth and yield . Comparing to CK, the time of heading moved up 4 d and maturing 5 d, the height of corn plant increased 4 cm, the seeds per ear increased 63.2 seeds, the weight of thousand seeds increased 2 g, and the yield increased 12.5%. Seed dressing and seedling spraying of zinc fertilizer moved up heading 2 d and maturing 3 d, increased height of corn plant 2 cm, increased seeds each ear 29.1 and 19.2 seeds, increased weight of thousand seeds 0.5 g and 1.0 g, and increased yield 7.6 % and 4.8 %. Seed soaking of zinc fertilizer moved up heading 2 d and maturing 4 d, increased height of corn plant 1.0 cm and seeds pre ear 11.8 seeds, weight of thousand seeds 1.0 g and yield 4.4%.
