Abstract：In order to select suitable calcium fertilizer for garlic in eastern Henan, an early-maturing garlic variety‘Cangbai No. 1’was used as test material, calcium sulfate, calcium carbonate and calcium chloride were applied, and non-calcium fertilizer was control, then the pythium root rot, soft rot and secondary growth were analyzed. The results indicated that the control efficiency of the root rot, soft rot and secondary growth of the garlic applied by 300 kg calcium sulfate per 667m2 were 89.69%, 84.50%and 70.59%respectively, were significantly higher than that of treatments. The prevention effect of calcium carbonate and calcium chloride on garlic pythium root rot were 74.80%and 49.03%, on garlic soft rot are 71.41%and 55.60%, on garlic secondary growth are 63.82%and 54.25%. The control efficiency of three treatments reached the sig?nificant level, as the order of calcium sulfate>lime>calcium chloride>control.
