牛粪用于盐碱地改良的风险与防控
Analysis of Risks and Prevention Strategies of Cow Manure Applied to Saline-Alkali Land
摘要
Abstract
As an important organic fertilizer resource,cow manure has broad application prospects in farmland soil improvement and green agricultural development.Nevertheless,the potential risks of salts and alkaline sub-stance input during its agricultural utilization are in urgent need of systematic evaluation.This paper reviews and analyzes the characteristics of soluble salts and alkaline substances in cow manure and their effects on saline-alkali land,with a focus on exploring the sources of salt in cow manure,the significance of electrical conductivity characterization,and the application risks of cow manure with different salt contents.From the per-spective of risk prevention and control,this paper puts forward measures such as regulating feed structure and drinking water quality at the source,implementing graded application of cow manure,and adopting fermentation for desalination combined with synergistic regulation of adsorbent materials during the composting process,so as to reduce salt-related risks and improve the safety of resource utilization of cow manure.The findings can pro-vide references for the scientific application of cow manure organic fertilizer in saline-alkali land and the revi-sion of relevant technical standards.关键词
