The invention provides a bio-control bacterium foliage
fertilizer, and preparation and application thereof. The bio-control bacterium foliage
fertilizer is prepared from the following materials in parts by weight: 1-3 parts of core bio-control
bacteria, 35-85 parts of biochemical
fulvic acid potassium, 10-50 parts of active SiO2, 2-6 parts of an
enzyme activity substance, and 2-6 parts of a
plant surfactant. The core bio-control
bacteria contain bio-control promoting
bacteria and
protein decomposing bacteria; the bio-control promoting bacteria comprise
bacillus subtilis and
trichoderma harzianum. The core bacteria in the bio-control bacteria foliage
fertilizer can rapidly grow on the surface of a
plant in a field planting manner and form a 'bio-control membrane' so as to prevent infection of
pathogenic bacteria at the surface of the
plant; the substances, such as
antibiotics and phytohormone, are generated in the processes of interaction with the
pathogenic bacteria and hyperparasitism, and a plurality of diseases of crops can be prevented, resisted or directly killed; the bio-control bacteria foliage fertilizer enables the crops to have
solid plant cell wall tissue, so that the ability of plant epidermis for directly resisting incursion of the
pathogenic bacteria and
insect pests is enhanced, and healthy growth of the crops is facilitated; the target of using a little of
pesticide or not is achieved, and the environmental
pollution is alleviated. Thus, the yield and the quality of the crops are improved.
