[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。
[Objective] The research aimed to study the prevention and control effect of arbuscular mycorrhizal fungi (AMF) and chloropicrin on the continuous cropping obstacle of strawberry. [Method] The effects of AMF on the growth, yield, quality and occurrence of Fusarium oxysporum f.sp. [Result] Chloropicrin fumigation soil could improve the AMF infection rate in strawberry root system and increase the biomass accumulation of strawberry. At the initial flowering and harvesting stages, the control effect of AMF on Fusarium wilt was 91.4% and 78.0% respectively after fumigation of soils with the recommended dose of chloropicrin at 80%, which was not obvious with the recommended dose of fumigation. The yield of strawberry treated by this treatment was 1509.7 kg / 667m2, the rate of increase was 3.9% higher than the recommended dose, and the fruit quality did not change obviously. [Conclusion] Inoculation of AMF with 80% of the recommended dose of chloropicrin fumigated soils had a good effect on obstacle of continuous cropping of strawberry.
