Study on the Technique and Method of Amelioration and Forestation in Coastal Alkali-Saline Land

Because of natural factors and artificial factors,the problem of soil salinization in coastal area is becoming serious,and greatly restricts the development of local economy.The quality and quantity of forestation in the alkali-saline soil are affected greatly in virtue of low land conditions,few tree species,severe pests,the unqualified technique,and so on.Combining with field investigation and experiments,the measures of reducing soil salinity and forestation technique were put forward.The results indicated that using the basic salinity-declining measures,rational close planting and mixed afforestation when the tree have high salt-toerance or in light saline soils,and adding tiny measures when the trees have low salt-toerance or in the heavy saline.
