| Abstract: |
| Through the pot-culture method with the gypsum as the comparison we discussed the effect of applying sulfur on the alkal-i saline soil in Pingluo Ningxia Hui Autonomous Region．The results indicate that applying sulfur can effectively reduce the soil pH and enhance the soil EC．The exchangeable Ca2+ Mg2+ and SO2-4— content increase significantly while the exchangeable Na＋ reduces significantly．The application of sulfur can also promote the corn’s growth． |
