| Abstract: |
| It has been well known that interplanting could reduce plant diseases. In this experiment, the effects of allium tuberosum interplanting and bio-organic fertilizer application on banana Fusarium wilt disease, soil microorganisms and soil enzyme activities were examined under field conditions. Results showed that banana disease index was significantly reduced by applying bio-organic fertilizer and interplanting allium tuberosum. Compared with A1B1, the disease controlling efficiency was 13.60%, 18.70% and 45.23% for A1B2, A2B1, and A2B2, respectively. Banana growth was significantly promoted by both interplanting allium tuberosum and applying bio-organic fertilizer. The greatest treatment effects were observed in A2B2, with stem length, leaf width, stem girth, and banana yield being increased by 20.01%, 6.58%, 10.56% and 55.56%, respectively, relative to the control. Applications of bio-organic fertilizer increased the population of bacteria and actinomyces in soil, but decreased that of soil fungi and Fusarium oxysporum. Interplanting banana with allium tuberosum increased the number of bacteria in soil, while significantly reduced that of fungi, actinomyces and Fusarium oxysporum. Soil enzyme activities were higher under allium tuberosum interplanting than banana alone. Bio-organic fertilizer could further increase the activities of soil enzymes. |
