AUTOMATIC FERTILIZING SYSTEM USING THE RECYCLING OF AGRICULTURAL WATER AND PURIFICATION TECHNOLOGY OF POLLUTED DRAINAGE WATER

摘要

PURPOSE: An automatic fertilizing system is provided to save water and to reduce the fertilizer application amount remarkably by using the recycled agricultural drainage water. CONSTITUTION: An automatic fertilizing system comprises a water-collection place(10); a water supply channel(20) provided with a water inlet hole(21); and a drainage channel provided with a water outlet hole. The water-collection place comprises a measuring device(11) measuring the flux and water quality at the position connected with the water supply channel; a fertilizer inlet port(12); a pump(13) connected with the water supply channel for pumping the water mixed with a fertilizer to the farmland(1); a guide hole(15) collecting the water from the drainage channel; and a supplemental water supply channel supplying water from a river(2) to the water-collection place.
