英文摘要	Biochar has the potential to decrease salinity and nutrient loss of saline soil. We investigated the effects of biochar amendment (0-10 g kg(-1)) on salinity of saline soil (2.8 parts per thousand salt) in NaCl leaching and nutrient retention by conducting column leaching experiments. The biochar was produced in situ fromSalix fragilisL. via a fire-water coupled process. The soil columns irrigated with 15 cm of water showed that biochar amendment (4 g kg(-1)) decreased the concentration Na(+)by 25.55% in the first irrigation and to 60.30% for the second irrigation in sandy loam layer over the corresponding control (CK). Meanwhile, the sodium adsorption ratio (SAR) of soil after the first and second irrigation was 1.62 and 0.54, respectively, which were 15.2% and 49.5% lower than CK. The marked increase in saturated hydraulic conductivity (Ks) from 0.15 x 10(-5) cm s(-1)for CK to 0.39 x 10(-5) cm s(-1), following 4 g kg(-1)of biochar addition, was conducive to salt leaching. Besides, biochar use (4 g kg(-1)) increased NH4+-N and Olsen-P by 63.63% and 62.50% over the CK, but accelerated NO3--N leaching. Since 15 cm hydrostatic pressure would result in salt accumulation of root zone, we would recommend using 4 g kg(-1)of biochar, 30 cm of water to ease the problem of salt leaching from the surface horizon to the subsoil. This study would provide a guidance to remediate the saline soil in the Yellow River Delta by judicious application of biochar and irrigation.
