为了确定生物有机肥 GSJ －1对连作马铃薯土壤疮痂病病原菌分布影响及对马铃薯疮痂病的防治效果，本试验进行了土壤疮痂病病原菌含量测定、马铃薯疮痂病病情田间调查。结果表明，连作土壤疮痂病病原菌在盛花期之前向根际富集，盛花期之后向匍匐茎和薯块富集。施用生物有机肥 GSJ －1显著降低了土壤疮痂病病原菌含量，比对照下降了19．6％～74．9％，且改变了土壤中疮痂病病原菌原有的分布规律：从连作处理的根际多于非根际改变为生物有机肥 GSJ －1处理的根际少于非根际，且对疮痂病的防效达到47．2％。

To evaluate effects of bio-organic fertilizer GSJ -1 on distribution of soil potato scab pathogens ,and also on the potato scab bio-control ,the content of soil scab pathogens was determined ,and the disease observation in field was carried out .The results showed that the potato scab pathogens of continuous cropping soil (CK) were concentrated to rhizosphere before flowering period ,and then moved to stolon and tuber consequently .The bio-organic fertilizer GSJ -1 significantly reduced the content of soil scab pathogens by 19 .6% ~ 74 .9% compared with the continuous cropping soil , and also changed the orders of the distribution of potato scab pathogens in soil .The order in continuous cropping soil had been as the following :rhizosphere > non rhizosphere ,which was turned into rhizosphere < non rhizosphere with GSJ - 1 treatment .In addition ,the prevention effect of GSJ -1 application on potato scab-control reached 47 .2% .
