Abstract: In recent years, the problem of soil continuous cropping obstacles has attracted widespread attention from scholars worldwide. This problem has severely restricted the sustainable development of the agricultural economy. Soil steam disinfection technology that is important for preventing and controlling soilborne diseases can effectively alleviate the problems caused by continuous cropping obstacles. This technology has the advantages of high efficiency, environmental protection, and cleanliness. This paper first introduces the basic principles and research status of soil steam disinfection technology. Secondly, it discusses the research progress of soil steam disinfection technology from the aspects of disinfection methods and terminal disinfection mechanism parameters. It points out the existing problems of the soil steam disinfection technology and its equipment, that is, not only failed to select a reasonable disinfection method and optimize the design of terminal disinfection mechanism according to the soil type but also lacked the research on the relationship between soil temperature field and harmful bacteria and viruses, the causes of continuous cropping obstacles caused by different crops, and the application of soil steam disinfection technology in facility agriculture. Finally, this paper points out the key research directions of soil steam disinfection technology in the future, that is, developing new disinfection methods, optimizing terminal disinfection mechanism, carrying out the research on the relationship between soil temperature field and harmful bacteria killing rate, deepening the research on continuous cropping obstacles in different crops, and carrying out the application of soil steam disinfection technology in facility agriculture.

摘要： 近年来，土壤连作障碍问题引起国内外学者广泛关注，该问题严重制约农业经济的可持续发展，而土壤蒸汽消毒技术可以有效地缓解土壤连作障碍问题，该技术具有高效、环保和清洁等优点。首先介绍土壤蒸汽消毒技术的基本原理和研究现状；其次，从土壤蒸汽消毒方式和末端蒸汽消毒机构的参数方面论述土壤蒸汽消毒技术的研究及应用进展，从而指出土壤蒸汽消毒技术及其机具现存的问题，即不仅未能根据土壤类型选择合理的消毒方式和优化设计末端消毒机构，而且缺乏对土壤温度场与有害菌和病毒之间关系、不同作物引起连作障碍原因的研究，同时也缺乏对土壤蒸汽消毒技术在设施农业中的应用；最后，指出未来土壤蒸汽消毒技术的重点研究方向，即研发新型消毒方式、优化末端消毒机构、开展土壤温度场和有害菌灭杀率二者关系的研究，并且要加深针对不同作物中连作障碍问题的研究和开展土壤蒸汽消毒技术在设施农业中的应用。
