To study the influence of complex formulation of �WoFengKang� compound microbial community and bio-organic fertilizer on allelopathic effect of cucumber fusarium wilt and field growth traits, in this experiment, different indoor treatments were taken to cultivate cucumber fusarium wilt using soil leaching liquor and Cucumis sativus growth index, fusarium wilt disease index were determined, so that allelopathic control effect of different dosages of compound microbial community on cucumber fusarium wilt can be investigated. The results showed that: compared with conventional CK, cucumber fusarium wilt cultured in different soil leaching liquor had smaller diameter. Where, colony diameter in treatment 3 was the smallest, which was 36.72 mm. Compound microbial community had certain allelopathic effect on cucumber fusarium wilt, and inhibition effect was shown with allelopathic effect reaching 27.13~43.91%. The above differently-treated soil was loaded to seedling-raising pot for Cucumis sativus planting. Cucumber fusarium wilt (FOC) was inoculated in the rough leaf stage of Cucumis sativus, thus reducing the disease index of cucumber fusarium wilt with obvious control effect reaching 55.94~72.63%. Where, treatment 3 demonstrated the best effect and allelopathic control effect reached 72.63% after 15d inoculation. The complex formulation of the two promoted vegetative growth of Cucumis sativus, lowered node of the first female flower bud, increased the number of female flowers within 30 nodes, so that 3.25d early flowering and 4.75d delayed seedling raising were achieved. Therefore, application of microbial community amid and after Cucumis sativus field planting has certain allelopathic control effect on cucumber fusarium wilt, which can effectively reduce the incidence of cucumber fusarium wilt and provide a scientific basis for the allelopathic prevention and control of soil-borne diseases in Cucumis sativus.

Cucumber Fusarium Wilt

Crop monocropping usually results in an enrichment of soil-borne pathogens in soil. Crop rotation is an environmentally friendly method for controlling soil-borne diseases. Plant rhizosphere microorganisms, especially plant-beneficial microorganisms, play a major role in protecting plants from pathogens, but responses of these microorganisms to crop rotation remain unclear. Here, we evaluated the effects of rotations with Indian mustard (Brassica juncea) and wild rocket (Diplotaxis tenuifolia (L.) DC.) on cucumber Fusarium wilt disease caused by Fusarium oxysporum f.sp. cucumerinum Owen (FOC). Cucumber rhizosphere bacterial community composition was analyzed by high-throughput amplicon sequencing. Bacteria, Pseudomonas spp., 2,4-diacetylphloroglucinol (an antifungal secondary metabolite) producer and FOC abundances were estimated by real-time PCR. Rotations with Indian mustard and wild rocket suppressed cucumber Fusarium wilt disease and cucumber rhizosphere FOC abundance. Crop rotations increased cucumber rhizosphere bacteria, Pseudomonas spp. and 2,4-diacetylphloroglucinol producer abundances. Moreover, crop rotations changed cucumber rhizosphere bacterial community composition and increased bacterial community diversity. However, crop rotations decreased soil inorganic nitrogen content and inhibited cucumber seedling growth. Overall, rotations with Indian mustard and wild rocket suppressed cucumber Fusarium wilt disease, which might be linked to the increased rhizosphere bacterial diversity and abundances of potential plant-beneficial microorganisms (such as Pseudomonas spp. and 2,4-diacetylphloroglucinol producer).
