| 摘 要： | 连作可短时间内带来经济效益，满足日益增长的粮食等农产品需求，但长期连作会加速土壤退化，导致作物减产和病害率增高，破坏土壤微生物结构平衡，不利于土壤生态系统的可持续发展。良好的土壤生态系统中有益微生物、有害微生物及植物间维持着相对平衡。微生物群落结构直接指示整个土壤生态系统的转化方向。通过总结前人在连作对土壤微生物菌群的影响及其修复连作土壤障碍方面的研究结果，探讨修复方式的利弊及其未来的研究方向，旨在为连作障碍土壤修复和植物生长发育创造良好条件，为保持土壤微生物群落结构平衡、保证土壤生态系统的可持续发展提供理论依据。

| Abstract: | Continuous cropping can bring economic benefits and meet the growing food demand in the short run, but it is not conducive to the sustainable development of soil ecosystem. Long term of continuous cropping can cause a lot of problems such as soil degradation, crop yield reduction, disease rate increase and destroy the balance of soil microbial structure. In a healthy soil ecosystem, beneficial microorganisms, harmful microorganisms and plants maintain a relatively balanced interaction. Microbial community structure often directly implies the development of the whole ecosystem. This article summarizes the effects of continuous cropping on soil microbial community and the previous experience of repairing continuous cropping soil obstacles, discuss the advantages and disadvantages of current remediation methods, in order to provide some suggestions for repairing continuous cropping obstacles and ensuring the sustainable development of soil ecosystem. |
