Abstract

Abstract: The vertical distribution of nitrogen content in maize canopies exhibits spatial heterogeneity. Clarifying its distribution patterns is conducive to improving nitrogen fertilizer promotion and control technologies,protecting the ecological environment of farmland and promoting sustainable agricultural development. This paper summarizes the measurement methods for nitrogen content in maize canopies and the research methods for vertical distribution of canopy nitrogen,and analyzes the characteristics,mechanisms and influencing factors of its vertical distribution,with the aim of providing a reference for research on vertical distribution of nitrogen in maize canopies.

Key words: Maize canopies, Nitrogen content, Vertical distribution, Influencing factors
