利通区是宁夏引黄灌溉、以种植业为基础、畜牧养殖业为发展的典型农业区域。近年来,随着全区冬麦北移和畜牧养殖业的蓬勃发展,保护性耕作技术在“免少耕种植冬小麦”和“麦后免少耕复种青饲玉米”生产应用中得到了长足的发展。2004至2005年,利通区通过农业部保护性耕作示范县建设项目,共推广免耕播种冬小麦、麦后免耕复种青饲玉米为主的保护性耕作技术模式4800hm2,2006年至2007年滚动发展两年,使该项技术得到进一步发展,2010年又通过农业部保护性耕作工程建设项 Litong is Ningxia Yellow River irrigation, based on planting, animal husbandry and aquaculture for the development of typical agricultural areas. In recent years, with the vigorous development of winter wheat and livestock husbandry in the whole region, the conservation tillage technology has been applied in production applications such as “less cultivation of winter wheat” and " Has made considerable progress. From 2004 to 2005, Litong District, through the construction project of conservation tillage demonstration counties under the Ministry of Agriculture, promoted the conservation tillage model of no-till sowing of winter wheat and wheat after no tillage and rehmannia maize 4800 hm 2 rolling development from 2006 to 2007 Two years, the technology has been further developed, in 2010 through the Ministry of Agriculture conservation tillage construction projects
