Abstract：To study the application effect of calcium fertilizer in garlic cropland in calcareous soil , a completely randomized block design of 5 treatments were set up with calcium sulfate ( gypsum ) amount of 0 (CK), 75, 150, 225 kg/hm2 and 300 kg/hm2 respectively.Then the growth period, bulb yield and single bulb weight of garlic were measured .The results showed that the application of calcium sulfate fertilizer made the seedling stage , scaly bud differentiation stage , stem elongation stage and bulb hypertrophy stage be 0~2 days in advance , while the maturation stage delayed 0~3 days.With the increase of fertilization amount , the resistance to diseases and insects had the trend from infection to lighter and then better resistance ; the single garlic bulb weight increased by 8.74%, 13.29%, 18.91% and 25.30% respectively compared to that of control, and the differences were highly significant; the yield increased by 8.73%, 13.27%, 18.90% and 25 .29%respectively , and the differences were highly significant .
