黄河淤区节水灌溉技术研究与应用

黄河淤区节水灌溉技术研究,目的在于对黄河机淤固堤形成的淤区实行节水灌溉。机井提水、管道输水、沟灌滴灌相结合的试验研究表明,该技术用地埋管输水到地头,用塑料软管代替沟畦在田间输水,用水的自然落差低压输水和配水对树木能准确、适时适量灌溉,具有节水节电、节地节肥、自由灵便、简单易行等特点,有效地提高了单位水量产值,节约灌溉投资,有较大的经济效益。

Research and application of water-saving irrigation technique in silted area of Yellow River

The research on the technique of water-saving irrigation in silted area of the Yellow River aims at the implementation of water-saving irrigation in the silted area formed by the practices of strengthening levee by machinery sitation.Through pumping water by machine,transferring water by pipes,and the combination of furrow and drip irrigation,water is diverted to the farmland through pipes buried underground,while plastic and soft pipes are used instead of furrow,thus water transfer and allocation by natural drop is ensured.This technique has several advantages,such as accuracy in irrigating plants with proper quantity at proper time;saving water,electricity,land and fertilizer,and free,flexible,and easy to manipulate.It improves the water production of per unit effectively,thus saves the irrigation investment and has great economic benefits.
