摘要
养殖粪肥还田利用是解决畜禽养殖污染问题的根本出路,也是破解农业面源污染难题、践行绿色发展理念的重要举措。本文以固体粪肥和液体粪肥为主要研究对象,在充分查阅国内外文献的基础上,介绍了粪肥分类、标准及粪肥农田利用主要技术,重点分析了粪肥还田对农田土壤中有机质、氮、磷含量影响及抗生素、抗性基因污染水平,概述了固体粪肥和液体粪肥还田的主要机械设备,并针对粪肥还田技术创新、监测体系、环境与安全风险和还田补贴等提出了具体建议。
Returning breeding manure to agricultural land is a method that can solve the problems of livestock and poultry breeding pollution and agricultural non-point source pollution and practice green development.This paper focused on the utilization of livestock and poultry breeding waste on farmland and reviewed the research progress of returning livestock manure to the field by consulting internal and external documents.This paper analyzed the impact of manure application to farmland on the organic matter,nitrogen,and phosphorus contents and the pollution of antibiotics and level of resistance genes in the soil.The main mechanical equipment used for the return of solid and liquid manure to the field was also summarized.Specific suggestions regarding technical innovations,monitoring systems,environmental and safety risks,and subsidies for returning manure to farmland were provided.
