Spatial and Temporal Changes of Cultivated Soil Fertility in Hebei Plain from 2019 to 2024 and Fertil-ization Strategies
摘要
Abstract
Studying the spatiotemporal variation characteristics of the main indicators of soil fertility can provide data support for the formulation and implementation of soil fertilization strategies.Taking the Hebei Plain as the research area,the spatial and temporal changes in soil fertility of cultivated soil in recent 5 years were clarified through quantitative analysis and Kriging spatial interpolation analysis,using soil organic matter,total nitrogen,available phosphorus,available potassium content,and pH value from 620 monitoring points for cultivated soil quality in the Hebei Plain from 2019 to 2024.The results showed that in 2024,the organic matter,total nitro-gen,available phosphorus,and available potassium contents in cultivated soil were 19.1 g/kg,1.17 g/kg,29.9 mg/kg,and 184 mg/kg,respectively,which in creased by 0.8 g/kg,0.04 g/kg,5.6 mg/kg,and 5 mg/kg compared to 2019.Overall,the cultivated soil in Hebei Plain is characterized by relatively low organic matter content,high total nitrogen content,insufficient available phosphorus content,and high available potassium content.The regional soil fertility is generally on the rise,but the spatial distribution heterogeneity is significant,with key fertility indica-tors such as organic matter,total nitrogen,and available phosphorus showing particularly significant spatial differentiation.It is recommended to implement classified policies for different regions to carry out fertil-izer management,implement actions to improve soil organic matter,and promote technologies for reducing fer-tilizers and increasing efficiency,in order to lay a solid foundation for the high-quality development of regional agriculture.关键词
