Abstract:
In the arid area after long-term drip irrigation, the accumulation of soil salinity has attracted a lot of attentions and concerns to researchers, which is also an important factor to limit the agricultural production and affect the oasis ecological stability and the sustain able application of drip irrigation. In order to elucidate the influence of applying drip irrigation technology on soil chemical properties, the percentage change of salinity and salt ions were monitored and analysed in a typical oasis area(Xiayedi irrigation area in Shihezi city of Xinjiang) from 2008 when the drip irrigation was first applied until to 2013. In mid April and mid October of every year, the change of salt ions were monitored in fixed-point soil layer. The total soluble salt content of soil samples were determined and then the content of Na
