摘要：

<正> The effect of applying biological organic fertilizer(BOF)on bacterial wilt incidence of tomato and soil microbial community under continuous cropping was studied. The results showed that all the tomatoes were infected by bacterial wilt in the control. The infection rates of tomatoes in the treatments with un-composted BOF and decomposed BOF were 55 and 50% respectively. Fatty acid methyl esters(FAME)analysis indicated soil microbial community changed sensitively after applying BOF. Soil FAME total content, relative fungi content and ratio of fungi to bacteria were significantly increased in both BOF treatments. The soil odd-number fatty acid proportion changed after applying BOF, aC15 : 0, iC17 : 0 decreased, while cyC17 : 0 increased in soil odd-number fatty acid proportion. BOF application would strengthen soil health and disease suppression. The content of C16 : 1 11c in soil microbial community was obviously increased after decomposed BOF application. It indicated that the growth of AM fungi could b
