| Abstract: | The fertigation technology was a new integrated water-fertilizer management technoliogy based on the water and nutrient requirements of crops, and it maintained the water and nutrient stabilization of root layer according to the real-time quantitative irrigation. The fertigation technology solved the problems involving irregular water-fertilizer supply and soil secondary salinization in traditional soil cultivation. In addition, it realized the goals of simplification, labor-saving, automation and high efficient use of water-fertilizer. To provide references for the extension and application of the fertigation technology, this article reviewed its technology principle, the main equipment and system-construction, technological basis and application examples both in China arid abroad in detail. |
