Sustainable plant production and salinity control in farm land under desertification

On the basis of regional natural resources and plant physiological functions found in the arid land, we proposed a farming model for sustainable and highly profitable plant production. The proposed farming model consists of the sustainable crop rotation in a field and the sustainable greenhouse cultivation of highly profitable vegetables. The sustainable crop rotation involves corns as the major crop, beets with uniquely high salt absorbing power and cover crops such as clover, where the soil salinity control can retard salt accumulation in the soil and the ground water. The sustainable and profitable greenhouse cultivation involves the soilless culture of high-sugar tomatoes by applying the salinized groundwater and the simple solar desalination system for the salinized groundwater.
