木霉制剂对土壤微生物数量和香蕉枯萎病的影响

采用稀释分离法研究木霉菌在土壤中的定殖动态及木霉制剂对土壤微生物数量的影响情况。结果显示：在含有基质的情况下,木霉菌在土壤中的存活数量呈先上升后下降的趋势;并且木霉菌在灭菌土中的存活量明显高于自然土。蕉园施入木霉制剂后,香蕉根围土壤中真菌的数量显著提高,枯萎病的发病率明显降低,处理区最高防效达63.5%。...

The colonization of Trichoderma in the soil and the effect of Trichoderma preparations on the amount of soil microorganism by dilution isolation were studied.The results showed that,in the case of containing substrate,the amount of Trichoderma in the soil tended to increase first and then decreased.The amount of Trichoderma in sterilized soil was significantly higher than that in natural soil.The number of fungi was increased significantly in the banana rhizosphere when the Trichoderma preparation was applied to banana plantations,and the incidence of banana wilt was significantly reduced.The highest control efficiency reached to 63.5 %.
