The invention discloses an embedded compound insecticidal probiotic and a preparation method and application thereof. In the preparation method, two kinds of inoculants, EM inoculants and BT mixed bacteria, are firstly rejuvenated together, and then through embedding The process encapsulates two bacterial agents in a selectively permeable membrane to form spherical microcapsules. In the embedding process of the present invention, an inner and outer two-layer embedding wall structure is adopted, the inner layer wall adsorbs and fixes the bacteria, and the outer wall provides strength and a protective layer, which fully guarantees the structural strength of the embedded body and the activity of the inner bacteria. It also provides slow-release properties to ensure the long-term effect of the inoculum. In the production process of the inoculum, the use of low-temperature freeze-drying and the addition of a protective agent ensures the maintenance of the activity of the inoculum and facilitates the improvement of the biomass of the inoculum after use. , so that the functional effect of the bacterial agent is more significant. In the construction of high-rise courtyards, it can be inoculated into the courtyard garden soil according to a certain proportion, which can promote the degradation of courtyard garbage, resist insects, and inhibit the activities of pests such as mosquitoes and flies. |
