| 摘 要： | 对内蒙古节水农业工程研究中心实验基地土壤进行化学分析 ,并探讨了该盐碱化土壤对玉米的胁迫作用 .实验结果表明 ,基地土壤 p H>8.5 ,可溶性盐分含量在 1 0 .0 9g·Kg以上 ,钠离子和氯离子含量分别在 3.4 0 g· Kg和 2 .86 g· Kg以上 ,属于氯化物型盐碱化土壤 .在这盐碱化土壤的胁迫作用下玉米种子发芽指数和活力指数受到显著抑制 ,发芽时间明显推后 ,幼苗生长受抑制 ,而且根对盐胁迫的敏感性大于地上部分 .

| Abstract: | Analysised the soil chemical component of NeiMongol Water Saving Agriculture Project Research Center experimental base ,and the effect of the saline alkali soil stress on Zea mays L. was studied. The experiment results showed that the soil samples pH was over 8.5, soluble salts content were over 10.09g/Kg, sodium ion and chloride ion content were respectively over 3.40g/Kg and 2.86g/Kg.According to this results,the soil was belong to chloride saline alkali soil. The Zea mays L.seed germination index and vigor index was inhibited,germination time was delayed,seedling growth was inhibited by the saline alkali soils.The Zea mays L.seedling root was more sensitive to saline alkali soil stress than aboveground part. |
