Abstract Three species of herbaceous plantsAndropogon chinensis,Miscanthus sinensis Zebrinus and Panicum virgatum were grown on saline-alkali soil of the Haiwan Zone of Fengxian,Shanghai, and their surface and 20-cm-deep rhizosphere soils were determined in terms of such indexes as pH,organic matter content,salt content and readily available potassium content so as to study the rhizosphere soil changes after growing the herbaceous plants on saline-alkali soil.The results showed that compared with the exposed soil,growing the herbaceous plants decreased the pH,organic matter content and readily available potassium content of both surface and 20-cm-deep rhizosphere soils,but the salt content was increased by growing A.chinensis and P.virgatum and was decreased only by growing M.sinensis.From the measured data it was concluded that the 3 species of plants could adapt well to growing on this saline-alkali soil and have a certain effect on improvement of saline-alkali soil.
