Abstract:The effects of different sulfur contents on physiological characteristics and
absorption of nitrogen, phosphorus and potassium were studied by nutrient solution. The results showed that the plant height, leaf length, leaf area and stem diameter of garlic(Allium sativum L.)treated by sulfur were higher than those without sulfur treatment. When sulfur content was 2.25 mmol·L-1, the photosynthetic parameter(Pn)and SOD activity in garlic leaf were higher. The POD, CAT and NR activity reached maximum when sulfur content was 1.50 mmol·L-1. The analysis showed that the total nitrogen and total sulfur contents in bulb and in bolt positively correlated very significantly with sulfur content in nutrient solution. When sulfur content was 2.25 mmol·L-1, the total phosphorus and total potassium contents in bulb and in bolt were higher.
