Effect of organic materials in controlling cucumber seedling diseases
有机物料减轻设施连作黄瓜苗期病害的微生物效应

In this work,pot experiments with organic materials were carried out to study the alleviation of Fusarim wilt and Rhizictonia wilt of cucumber and the changes of soil microorganism.The results showed that rice straw,pig feces and wood chip could alleviate Fusarium wilt and Rhizoctonia wilt of cucumber,and the effect of rice straw was most significant,followed by pig feces and wood chip.The amount of soil microbes was higher in organic materials treatments than in control. The total amount of actinomyces and epidhyte which can inhibit the growth of pathogen was the highest in rice straw treatment,followed by pig feces treatment.No significant change of soil microbial amount was found in wood chip treatment.
