Effects of water-nitrogen coupling on growth and yield of densely planted maize in the Hexi Oasis irrigation area

Abstract

 In order to explore the influence of different water-nitrogen coupling models on the growth and development, yield formation and water-nitrogen utilization efficiency of densely planted maize, a total of 10 treatments were set up by setting up three irrigation levels and three nitrogen application gradients , and a contrast treatment CK, to study the influence of different water-nitrogen coupling models on the growth condition of densely planted maize, yield, and to provide theoretical basis for the establishment of a densely planted maize water-fertilizer integration and efficient irrigation nitrogen application scheme and the rational utilization of water-nitrogen resources. It will provide theoretical basis for the establishment of efficient irrigation and nitrogen application program and rational utilization of water and nitrogen resources in closely planted maize.
