摘　　要：The amount of phenol compounds in the soil increased after adding organic material into the soil. It was found that p-hydroxybenzoic acid, p-coumaric acid and frulic acid alleviated Fusarium wilt of cucumber, the alleviating effect of p-hydroxybenzoic acid was the best, followed by p-coumaric acid and frulic acid. The total amount of bacterial, actinomyces and fungus in high phenol compounds treatment decreased than that of control treatment, while the microorganisms’ amount in low phenol compounds treatment increased. Phenol compounds inhibit the growth of pathogen.The amount of phenol compounds in the soil increased after adding organic material into the soil.
