摘　　要：[目的]研究丛枝菌根真菌(AMF)与氯化苦对草莓连作障碍的防控作用。[方法]通过小区试验测定氯化苦熏蒸土壤后接种AMF对连作草莓生长、产量、品质及枯萎病发生情况的影响。[结果]氯化苦熏蒸土壤可提高AMF在草莓根系内的侵染率,增加草莓生物量累积。在始花期和收获期,氯化苦80%推荐剂量熏蒸土壤后接种AMF对枯萎病的防效分别为91.4%和78.0%,均与推荐剂量熏蒸防效差异不明显;该处理草莓产量为1509.7 kg/667m2,增产率比推荐剂量熏蒸高3.9%,且果实品质未发生明显变化。[结论]氯化苦80%推荐剂量熏蒸土壤后接种AMF对草莓连作障碍有较好缓解效果。[Aims] The research aims to study the control effect of inoculating arbuscular mycorrhizal fungi after the soil was fumigated with chloropicrin on continuous cropping obstacle of strawberry. [Methods] The plot experiment was conducted to determine the effects of inoculating arbuscular mycorrhizal fungi after the soil was fumigated with chloropicrin on the growth, yield, quality and occurrence of wilt disease of strawberry. [Results] The infection rate of arbuscular mycorrhizal fungi in strawberry roots and the biomass accumulation both increased after the soil was fumigated with chloropicrin, significantly. At the beginning of flowering stage and harvest stage, the control effects of inoculating arbuscular mycorrhizal fungi were 91.4 and 78.0%, respectively, with no significant difference with the control, after the soil was fumigated with chloropicrin at the eight percent of recommended dosage on wilt disease. The yield of the treatment was 1509.7 kg/667m2 with a higher increase rate 3.9% than that of controls and a good quality. [Conclusions] The control effect of inoculating arbuscular mycorrhizal fungi after the soil was fumigated with chloropicrin at the eight percent of recommended dosage on continuous cropping obstacle of strawberry was good.
