Abstract
Fengxiang District is located in the Weibei Dry Plateau with scarce water resources and frequent seasonal droughts during the critical growth period of wheat and maize.Conventional flood irrigation leads to severe loss of wa-ter and fertilizer,with low resource utilization efficiency.Combined with local farming characteristics of scattered small plots and coexistence of smallholders and large-scale farms,this paper sorts out supporting parameters of drip irriga-tion,micro-sprinkler irrigation and reel sprinkler irrigation,and establishes a compound cultivation mode of wide-nar-row row maize planting coupled with drip irrigation and integrated water-fertilizer management.Matching irrigation and fertilization quotas,field laying standards and equipment operation specifications are formulated for different crops and growth stages,and the comprehensive benefits of water saving,fertilizer reduction and yield increase are quantified.The localized practical technical system is suitable for Weibei Dry Plateau,and can provide technical support for drought resistance,stable grain yield and large-scale popularization of water-saving irrigation technology.关键词
