精准施肥对农田养分流失的影响及其优化策略
摘 要
随着现代农业的快速发展，农田养分管理成为保障作物产量与品质、维护生态环境平衡的关键环节。本研究旨在探讨精准施肥对农田养分流失的影响及其优化策略。首先，通过梳理精准施肥理论、农田养分流失理论以及环境经济学与农业可持续发展理论，为后续研究奠定理论基础。随后，分析精准施肥对土壤养分含量、水体富营养化及大气环境的影响，揭示精准施肥在减少农田养分流失方面的作用机制。针对当前精准施肥实施过程中存在的技术推广、监测评估、政策法规及社会认知等方面的问题，本研究提出了一系列优化策略，包括加强技术推广与培训、完善监测与评估体系、强化政策与法规支持以及提升社会认知与参与度等。研究成果将为精准施肥技术的广泛应用提供科学依据，为农田养分管理政策的制定提供参考，推动农业向更加绿色、高效、可持续的方向发展。

EFFECT OF PRECISION FERTILIZATION ON FARMLAND NUTRIENT LOSS AND ITS OPTIMIZATION STRATEGY
ABSTRACT
With the rapid development of modern agriculture, farmland nutrient management has become the key link to ensure the crop yield and quality and maintain the balance of ecological environment. The aim of this study was to investigate the effects of precision fertilization on farmland nutrient loss and its optimization strategies. First of all, through the analysis of precision fertilizer application theory, farmland nutrient loss theory, environmental economics and agricultural sustainable development theory, it laid a theoretical foundation for the subsequent research. Subsequently, the effects of precision fertilization on soil nutrient content, water eutrophication and atmospheric environment were analyzed, and the mechanism of precision fertilization in reducing nutrient loss in farmland was revealed. In view of the current precision fertilization in the process of technology promotion, monitoring, policies and regulations and social cognition problems, this study puts forward a series of optimization strategy, including strengthening technology promotion and training, improve the monitoring and evaluation system, strengthen the policy and regulations support and improve social cognition and participation, etc. The research results will provide a scientific basis for the wide application of precision fertilization technology, provide a reference for the formulation of farmland nutrient management policies, and promote the development of agriculture to a more green, efficient and sustainable direction.
