从1983 年开始,在黄土高原长城沿线风沙区东部的榆林地区进行水稻节水灌溉及配套技术试验,先后围绕水稻生产中的灌溉、良种、育秧、密度、施肥等主要技术问题开展了一系列研究和优选组配,形成适合于当地生产的节水技术,从1993 年起大面积推广应用,较常规技术可节水10440~14745 m 3/hm 2,增产11.1 % ~24.2 % 。1996 年推广这一配套技术 5800 hm 2,平均单产 8356.5kg/hm 2,较常规生产增产11.1 % 。
Starting from 1983, experiments on rice water-saving irrigation and its supporting technologies were conducted in Yulin area, east of the wind-blown area along the Great Wall along the Great Wall of the Loess Plateau. A series of studies were carried out on major technical issues such as irrigation, seed quality, seedling raising, density and fertilization in rice production And the preferred combination to form a water-saving technology suitable for local production. Since 1993, it has been popularized and applied in a large area. Compared with the conventional technology, the water-saving technology can save 10440 ~ 14745 m 3 / hm 2 and increase the yield by 11.1% ~ 24.2%. In 1996 to promote this matching technology 5800 hm 2, the average yield of 8356.5kg / hm 2, 11.1% increase over conventional production.
