Garden selection and soil improvement nursery should choose fertile soil, adequate water, irrigation and drainage, groundwater table below 1.2 m, the soil salt content of less than 0.2% saline soil, poplar, black locust , Liaoning jujube, poinsettia, willow, mulberry, willow, Amorpha fruticosa and other tree seedlings, can achieve better results. Such as low-lying, poor drainage, salt heavier saline-alkali land can be used to build salt water table washing, table width of 10 to 20 meters, depending on the topography of the terrain, usually 100 to 300 meters. station
