摘要
连作障碍是马铃薯产业可持续发展亟待解决的问题,本文从土壤营养、土壤酶活、土壤微生物、根系分泌物4个方面综述了马铃薯连作障碍的研究现状,并阐述了作物复合型种植对土壤连作障碍的缓解作用。连作障碍可能是作物-土壤系统内部诸多因子综合作用的结果,单一因子的论述很难清楚解释其形成的原因,探究多因素复合影响机制有其必要性及意义,持续的研究有利于做出较合理的解释。复合型种植是一种有效缓解马铃薯连作障碍的调控技术。今后该领域的研究应注重多学科联合、完善研究方法、扩展研究领域,才能系统揭示连作障碍形成机理。
The obstacle for continuous cropping is a demanding prompt solution problem of potatoes industry sustainable development. From four aspects including soil nutrition, soil enzyme, soil microbes and root exudates, we summarized the research status of obstacles about potatoes continuous cropping and expounded the mitigation effects of integrated cultivation on the obstacles of soil continuous cropping. The obstacle of continuous cropping could be the both crop and soil systems interior a result of the complex interaction of multiple factors. It is very difficult for single factor discussion to make a clearly explanation it the cause formation, therefore to explore the multifactor composite effect mechanism is necessary and meaningful. There is the need for continuous research to comprehensively determine the mechanism of continuous cropping obstacle. The integrated cultivation is an effective mitiga- tion control technology of potatoes continuous cropping obstacle. Future studies on this domain should be emphasized on the combination of muhidisciplinary and perfecting research methods as well as enlarging research field, which can systematically reveal the formation mechanism of continuous cropping obstacles.
