农业作为国家经济的基础，其发展状况对粮食安全、农村经济和生态环境保护至关重要。然而，农业生产中不合理的肥料使用会降低作物产量和品质，同时造成土壤和水体污染，威胁农业生态可持续发展。在中国，农村农户的肥料选择行为是影响农业生产及环境的关键因素之一。因此，研究农户肥料选择偏好及其影响因素对于指导科学施肥、提高生产效率和改善环境污染具有重要意义。本文尝试以农户风险偏好为核心变量，结合中国农户施肥选择多样性，基于农户调查数据，跨学科探索农户施肥行为，并从异质性角度进一步探讨。旨在为农户施肥行为研究提供新颖细致的解释，并为中国农业环境污染的跨学科研究提供融合进路与经验借鉴，有助于促进农业生产的可持续发展，改善农业环境。

Agriculture, as the foundation of the national economy, is of great importance to food security, rural economy, and ecological environmental protection.However, irrational use of fertilizer in agricultural production can reduce crop yields and quality, and cause soil and water pollution, threatening the sustainable development of agricultural ecology.In China, farmers' fertilizer selection behavior is one of the key factors to affect agricultural production and the environment.Therefore, the analysis of the farmers' fertilizer preference and its influencing factors is of great significance for guiding scientific fertilization, improving production efficiency, and improving environmental pollution.This paper attempts to explore farmers' fertilizer application behavior across disciplines, based on farmer survey data, with farmers' risk preference as the core variable, which takes into account the diversity of fertilizer choices in China.The aim is to provide a novel and detailed explanation for farmers' fertilizer selection behavior research and provide a fusion approach and experience for interdisciplinary research on agricultural environmental pollution in China, which is conducive to promoting sustainable agricultural development and improving agricultural environment.
