Effects of combined application of zinc，molybdenum and humic acid on chlorophyll content，antioxidant，garlic yield and soil physical，chemical and biological indicators were studied in this paper. The experiment consists of 4 treatments，including regular fertilizing（CK），regular fertilizing +zinc+molybdenum（T1），regular fertilizing+humic acid（T2），regular fertilizing+ zinc+molybdenum+humic acid（T3）. The results indicated that T3 could not only increase the plant height，stem diameter，garlic diameter and yield，but also significantly increase the chlorophyll content of garlic leaf blades，improve the activities of POD，SOD and CAT.T3 was also beneficial for strengthening soil enzyme activity，improve soil physical and chemical properties. The garlic plant treated by T3 could yield 20.13 t·hm-2，which was 14.83% more than that by traditional fertilizing at locality. To put it short，T3 has very good effect on increasing garlic yield and improving soil fertility in Henan Province.
