Abstract

The invention discloses a preparation method of a biologically modified composite material. The biologically modified composite material is applied to the field of vegetable plant disease and insect pest prevention and treatment. Nonmetallic minerals are selected as raw materials, and are subjected to process processing of dry process purification, biocontrol bacterium screening, nonmetallic mineral mixture biocontrol bacterium fixation, granulation, drying and the like. The preparation method has the advantages that the raw materials are nonmetallic minerals; no toxicity and harmlessness aregenerated in the production process; no pollutant discharge can be realized; high efficiency, energy saving and environment protection are realized; green and harmless farm products can be produced; the economic value of the farm products is improved; meanwhile, the human body health is facilitated.

Description

technical field [0001] The invention relates to a preparation method of a biomodified composite material, which is used in the field of vegetable pest control. Background technique [0002] In the production of melons, fruits and vegetables, due to years of continuous cropping, blind fertilization, abuse of pesticides, and unreasonable field operations, the soil environment has deteriorated, leading to land compaction, severe pesticide residues, phytotoxicity, and repeated cropping diseases. Decrease, poor air permeability, reduced decomposition and reduction ability, and the yield and quality of fruits and vegetables have dropped significantly. In addition, in some areas, the awareness of environmental protection is weak and the dependence on chemical fertilizers is strong, which leads to the deterioration of the soil and serious water pollution, which leads to an increase in the incidence rate. Now the groundwater above 10 meters in the vast rural areas becomes astringent ...
