Bibliometric Analysis of Straw Return to Field Research on Soil Nutrients Based on CiteSpace

Abstract

Soil nutrients are one of the important factors affecting crop growth, and straw return to field is an effective method to improve the soil nutrient composition in agricultural ecosystems. To optimize agricultural production and enhance the resource utilization efficiency of agricultural waste, this paper conducts a comprehensive analysis of annual publication volume, collaborating authors, journal analysis, research institutions, and the frequency and centrality of keywords based on the research papers related to straw return to field and soil nutrients collected in the China National Knowledge Infrastructure (CNKI) database from 2004 to 2024. With the aid of CiteSpace visualization software and bibliometrics, the results show that the number of Chinese-related articles has generally shown an upward trend since 2009. The main authors include Huancheng Pang, etc. The primary publishing journals are mainly “Jiangsu Journal of Agricultural Sciences,” among others. The main institutions include the Institute of Agricultural Resources and Regional Planning, etc. The research hotspots are unfolded from two aspects of straw return to field and soil nutrients, and related soil enzyme activity, and crop yield may become future research hotspots, which also provide reference significance for further leveraging the resource utilization of straw return to field.
