Abstract :
By means of experimental study on saline-alkaline soil in the western of Jilin Province, samples of different salinity were collected in the areas of planting Melilotus Offcinalia (MO) in Jiangjiadian pasture. Soil bulk density, soil moisture content and field moisture capacity were determined. Based on the above data analysis, range and trend of change about these indicators after cultivating MO were discussed. The results indicated that MO may significantly improve the soil structure and increase water retention ability. Soil bulk density was reduced 0.02 ~ 0.45 g/cm3, field moisture capacity increased 0.03 ~ 9.56%. The study provided a more effective biological technology to improve the degraded vegetation and saline-alkaline field production in semi-arid area.
