摘 要：正Introduction Alkalinized soils are expanding over the western area in Jilin province of China and have been partially used as ***-grass（Puccinellia tenui flora）,a perennial plant in the Poaceae family,grows well in those areas,unlike most grasses which do not grow in soils with very high levels of *** has been observed that some grasses become established after several years of cultivation of the alkali grass in these ***,it is expected that the grass could be used to improve alkalinized *** in soil characteristics from alkali-grass cultivation,however,were not determined in detail in previous *** present study,therefore,was conducted to clarify the effects of alkali-grass cultivation on the chemical components and physical characteristics of alkali soil in Jilin.
