畜禽粪肥还田全盐量限值研究

Study on the Total Salt Content Limit for Returning Livestock and Poultry Manure to Fields

摘要:

本研究主要聚焦于畜禽粪肥还田全盐量限值展开分析，针对畜禽粪肥的特点，深入分析了其内部盐分来源与含量特征，明确其施用对土壤盐分的影响，且施用后对盐碱土区域、地下水环境质量以及植物等方面的影响。在此基础上，根据我国土壤与农业生产实际情况，优化农业生产模式、制定科学合理的畜禽粪肥还田全盐量限值。通过科学制定肥料盐分相关标准，能够平衡农业生产与生态环境保护之间的关系，为农业可持续健康发展提供保障。

Abstract:

This research focuses on the total salt content limit for returning livestock and poultry manure to fields.Aiming at the characteristics of livestock and poultry manure, it conducts an in-depth analysis of the sources and content characteristics of salt in manure, clarifies the impact of manure application on soil salt content, as well as the impacts on saline-alkali soil areas, groundwater environmental quality and crops. On this basis, according to the actual conditions of soil and agricultural production in China, it is necessary to optimize agricultural production modes and formulate scientific and reasonable total salt content limits for returning livestock and poultry manure to fields. By scientifically formulating standards related to fertilizer salt content, the balance between agricultural production and ecological environmental protection can be achieved, and the sustainable, green and healthy development of agriculture can be ensured.
