Abstract:: With 11 years continuous cropping soil as research object，effects of two bio-control strains，Bacillus subtilis and Trichoderma harzianum，on cucumber seedlings and soil microbes population were tested under pot experiment with continuous cropping soil of cucumber.Two levels，106 or 109 of per millilitre，of each bio-control microbe were designed to obtain proper incubated concentration into soil.The results showed that cucumber growth factors increased stimulated significantly in high concentration of inoculation of Bacillus subtilis and Trichoderma harzianum，such as chlorophyll，photosynthetic rate，shoot dry weight，root length and root volume and so on.At the same time，the incidence of disease of leaves wilt decreased significantly with bio-control microbe than without (CK).There were significant correlation between microbial population with available phosphorus or potassium，as actinomyces and fungi.In short，incubation of bio-control Bacillus subtilis and Trichoderma harzianum stimulated cucumber seedling growth in continuous cropping soil and decreased incidence disease of leaves，especially in high concentration incubation.
