Abstract

The invention discloses a preparation method of a crop disease-resistant immune fertilizer, and belongs to the technical field of crop fertilizers. The preparation method comprises the following steps: separately culturing lactic acid bacteria, bacillus and penicillium bilaiae, then mixing to form mixed bacterial liquid a, filtering, adding xanthan gum, polyvinyl alcohol resin, tea seed powder andcaramel color, and stirring to prepare film forming bacterial liquid b for future use; taking organic matter and nitrogen, phosphorus, potassium, silicon, calcium, magnesium, iron, boron and inert viscous materials, mixing in proportion, preparing into a material c, spraying water on the material c, and extruding; polishing the extruded material c, placed in high-temperature drying equipment, andsieving material particles c1; transferring the material particles c1 to a rorate-drum stirring tank, adding the standby film forming bacteria liquid b, stirring and uniformly mixing to prepare coated particles d; and dying the coated particles d to prepare the disease-resistant immune fertilizer. The invention solves the problem that the existing immunological preparation has a single function.

Description

technical field [0001] The invention belongs to the technical field of crop fertilizers, and in particular relates to a preparation method of a crop disease-resistant immune fertilizer. Background technique [0002] When plants are stimulated by the outside world or under adverse conditions, they can produce immune responses by regulating their own defense and metabolic systems. This defense response or immune resistance response of plants can delay or alleviate the occurrence and development of diseases in plants and reduce chemical stress. Reduce the use of pesticides and chemical fertilizers, thereby reducing pesticide residues in agricultural products. However, most of the basic principles of creating and controlling plant disease drugs are to target pathogenic bacteria, and then further develop drugs that can quickly and comprehensively kill the target into pesticides according to the requirements of pesticide registration, ignoring the host plant itself that is harmed ...
