Effects of cultivation of Puccinellia tenui flora on the chemical and physical characteristics of alkalinized soil in western areas of Jilin

摘要

Alkalinized soils are expanding over the western area in Jilin province of China and have been partially used as grasslands.Alkali‐grass ( Puccinellia tenui f lora), a perennial plant in the Poaceae f amily, grows well in those areas, unlike most grasses which do not grow in soils with very high levels of pH.It has been observed that some grasses become established after several years of cultivation of the alkali grass in these soils.Thus, it is expected that the grass could be used to improve alkalinized soil.Changes in soil characteristics from alkali‐grass cultivation, however, were not determined in detail in previous studies.The 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.
