摘要
粉煤灰是燃煤电厂产生的固体废弃物,年排放量巨大,其资源化利用主要集中在建材、环保、化工及农业等方面。粉煤灰中含有多种利于植物生长的元素,且基于其特殊的理化性质,可作为潜在的土壤改良剂应用于农业,对改良土壤酸碱性、提高土壤质量、促进植物生长等表现出积极的作用。本文综述了粉煤灰在农业方面的应用进展,并对其农业应用中存在的问题及未来的发展进行了分析和展望,以期为粉煤灰在农业领域的资源化利用提供参考。
Fly ash is a solid waste generated by coal-fired power plants,with huge annual emissions.Its resource utilization mainly focuses on building materials,environmental protection,chemical industry and agriculture.Fly ash contains a variety of elements that are beneficial for plant growth,and based on its specially physical and chemical properties,it can be used as a potential soil conditioner in agriculture,which plays a positive role in improving soil acidity and alkalinity,improving soil quality and promoting plant growth.This paper summarized the application progress of fly ash,analyzed the problems in agriculture application and prospected the future development,so as to provide references for the resource utilization of fly ash in agriculture.
