Abstract: This paper is to make a comprehensive and systematic review of research progresses and future directions of the study on microplastics in the farmland environment, to introduce morphology, sources and accumulation of microplastics (MPs), and effects of MPs on structure and function in the soil both in China and in other countries as well. This paper also elaborates ecological effects of MPs on organisms, plants and the effects of MPs and cadmium compound pollution on plants. In the end, the paper puts forward views and prospects of future researches on microplastics in the farmland environment. This paper is expected to be able to provide information and scientific guidance for comprehensive understanding of the presence and future of microplastics in the farmland environment.
