| 中文摘要: |
| 采用盆栽试验方法,以石膏为对照,探讨硫磺对宁夏平罗盐碱土的改良效果。结果表明:施用硫磺能有效降低土壤pH值,增大EC值;土壤中Ca2+、Mg2+和SO2-4含量增加明显,交换性Na+有一定程度的降低;玉米生物量增加,其中低硫用量效果最为明显,增加了18.4%。 |
| 英文摘要: |
| 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． |
