Abstract: Coastal saline land in Tangshan City was taken as the research object, and some experiments were carried out in Nanbao salt field. Seed-base technique and some measures of site preparation were applied to test the survival rate and growing state of Morus alba Linn seedling when planting in serious saline soils. Results indicated that the seed-base technique performed better effects on improving soil and cutting off the salt flow. After the seed-base technique was employed, most of the seedlings survived and grew well in heavy saline soils compared to the control. This experiment implies that the seed-base technique could create better growing environment for Morus alba Linn seedlings, which will increase survival rate and improve trees growing. It can be concluded that the integrated technique is effective and practical in serious coastal saline land in gulf of Bohai Sea, which will offer afforestation technique for Tangshan City and advance the afforestation development in heavy saline soils.
