Abstract: This article reviewed the research progress of several physical and chemical methods that can reduce the emission of fumigation gases during soil fumigation to prevent soil-borne harmful organisms, such as covering plastic films, increasing application depth, increasing soil moisture content, increasing soil bulk density, adding biochar, using drip irrigation systems, developing new fumigant formulations, and adding organic and inorganic fertilizers to the soil surface. Although using the above single method can reduce the emission loss of fumigation gas to varying degrees, combining the above technologies can achieve more ideal emission reduction effects. At the same time, it is recommended that relevant government management departments, researchers, and growers work together to promote the practical application of alternative emission reduction technologies besides plastic films covering. This effort aims to the use of plastic films while achieving a reduction in fumigation gas emissions, thereby minimizing the adverse impacts on the ecological environment.
