Abstract:: In order to investigate the simple and practical afforestation patterns on saline land which can reduce the waste of large-scale new soil, variety of reform measures were applied to clay salinization soil including hole-based padded film and configuring hole-based with new soil, etc. At same time, water-salt dynamic data was collected at points of inside and outside hole in the platformⅠ, Ⅱ, Ⅲ with different salinity. Results showed that: moisture content and conductivity of the platformⅠ, Ⅱ, Ⅲ in the hole compared with the outer, the average moisture content inside the hole was higher than outside, and soil moisture content at 20-40 cm of the seedling root reached the maximum value; the average conductivity inside the hole was lower than outside, and soil conductivity at 60-80 cm met the minimum because of the gravel layer draining and preventing salt. Hole-based padded film with new soil effectively reduced water infiltration and evaporation in the planting hole, and prevented the infiltration of soil salinity outside. It played a role in preventing the infiltration of salt and reducing the evaporation. So, it provided a good local soil environment for seedling growth. Therefore, the model can reduce soil salinity, as well as improve seedling survival and preservation rate. In addition, it has a lower cost than completely new soil, is simple to operate and is easy to implement, and will be broad prospects.
