Progress of Research on Alleviating Obstacles of Continuous Cropping by Soil Sterilization and Arbuscular Mycorrhizal Fungi
The continuous cropping obstacles have been widespread in horticultural production,and the reasons were complicated.It has done serious harm to the ecosystem consisting of soil,plants and rhizosphere microorganisms.The economical and convenient soil sterilization technologies effectively alleviate the obstacles,among the sterilization technologies,high temperature sterilization and reductive soil disinfestation improve soil environment.Meanwhile,symbiotic associations between arbuscular mycorrhizal(AM)fungi and plant root systems is helpful to reconstruction of rhizosphere ecosystems.Focused on the continuous cropping obstacles,this paper reviewed the effect of high temperature sterilization,reductive soil disinfestation and arbuscular mycorrhizal fungi on the obstacles alleviation and their mechanisms.Furthermore,meaningful research works in this field were prospected.The review provided a theoretical and technical basis for the alleviation of continuous cropping obstacles in horticultural production.
