Abstract: [Objective and Method]The field experiment was conducted to study the effect of sulphur fertilizer using garlic plant height, stem diameter, leaf area per plant,rate of rust diseased plant, yield of the bulb and the flower stalk of garlic by use of the Xinjiang White Garlic as material.[Result]The result showed that sulphur fertilizer could accelerate the garlic's growth and development in Xinjiang Aheqi garlic area, increase garlic plant height, the stem diameter and the leaf area per plant, enhance the capacity of rust resistance,increase yield of the bulb and the flower stalk of garlic. It is better that the application of sulphur fertilizer was 12 kg/667m~2. To compare with no sulphur , the garlic plant height was increased by 7.8;, the stem diameter increased by 17.5;, the leaf area increased by 33.3;, the rate of rust diseased plant reduced by 80;, the bulb yield per unit area increased by 14.1;, the yield of the flower stalk of garlic increased by 16.1;. When the sulphur was within 0-12 kg/667 m~2,[Conclusion]the yield of the garlic was increased with the increasing of sulphur fertilizer.However, when the sulphur was exceeded by 12 kg/667 m~2, the yield was decreased.
