| Research Abstract |
In order to recover the growth of the pasture in the sodic alkaline soil of North-eastern district of China, the chemical characteristics of the soil and tolerance of the gramineous plants growing there were investigated. The result showed that the soil had high pH around 10 and electron conductivity (EC). It was shown that much amount of Fe and Al was eluted by water. It was shown that the tolerance to high EC, especially to bicarbonate rather than sodium ion is more prerequisite in the tolerant plant. Furthermore, it was shown that the plant had higher activity to release phytosiderophore in its roots.
