The increasing severity of soil contamination, salinization and alkalization make soil solute transport one of the key issues in soil science study. With the increasing demands of growing population for food and water, saline water utilization and saline-alkaline soil amelioration are of great importance. Based on the review of national and international research results of soil solute transport, saline water utilization and improvement of alkaline soil with drip irrigation under film, both theoretical anal...
