Abstract:: By the impact of the Yellow River alluvial water，the soil of Zhongmu County take on weakly alkaline reaction.Due to the local farmers planting garlic all the year round on the soil，causing the poor plant growth，and bring down the yield and quality.Taking garlic as test material in this experiment，adoptting the contrast test of calcium sulfate (gypsum powder),calcium chloride，calcium superphosphate，calcium magnesium phosphate fertilizer，without calcium fertilizer (CK) to find out a calcium fertilizer which was suitable for local production，and provided the basis for the scientific application of fertilizer.The results showed that the calcium fertilizer treated plants were balanced function，calcium sulfate，chloride，calcium superphosphate，calcium magnesium phosphate processing plant were higher than the control average plant dwarfism 0.98%，3.57%，1.95% and 2.79%，and the plant height was dealt with calcium sulfate were in the optimum range，and the plants were beefiest；chlorophyll SPAD value respectively，compared to the control increased by 10%，8%，7% and 8%；after three trials of calcium treatment，garlic fruit weight and yield increment showed that calcium sulfate was the highest，calcium chloride was the second，superphosphate was the third，calcium-magnesium-phosphorus was the fourth，the control was the fifth.
