Abstract：Taking a bad saline-alkali soil by sea in the city of Tangshan as the research object,adopting some measures,such as sowing by seed-bases to breed seedlings,building stair-fields,digging open drains,constructing isolating layers,transplanting seedlings in carrying soil columns etc,and exploring a new technology of seed-base for afforestation on saline-alkali soil by sea.The results showed that the seed-bases had a certain function to anti-salinization.Vermiculite and pearlite had a better effect than peat in the rate of germination,and the seed-base that was made by carrying soil,peat,vermiculite and pearlite in the volume ratio of 5∶1∶2∶2 had the highest rate of germination.The isolating layer of slag was better than that one of construction waste in anti-salinization,and the stair-field with a slag layer in the shape of two stripes from south to north and one strip from east to west had the best effect.The carrying soil columns could prevent transplanting eedlings from the harmful effects of salinization,which made most of transplanting seedlings to survive.The results could provide a certain technical support for afforestion on saline-alkali soil by sea.
