Fertilizer additive capable of enhancing immunity of crops and preparation method of additive

Abstract

The invention discloses a fertilizer additive capable of enhancing immunity of crops and a preparation method of the additive. The additive is prepared from raw materials in parts by weight as follows: acrylic acid, starch, N,N'-methylenebisacrylamide, sodium naphthalene-1-acetate, an EM (effective microorganism) agent, dried cattle manure, saw dust of Melia azedarach, garlic straw, tobacco residues, attapulgite powder, corn bran, chaff, fresh ginger residues, itaconic acid, plant-sourced raw materials and a proper amount of water. The additive is resin particles containing liquid fermentation products and insect-resistant volatile substances of plants, main liquid fermentation products are produced by decomposing organic matters by the aid of microorganisms, most products are outer protecting substances such as antibiotics, toxins and hormone active ingredients, the immunity of the plants can be enhanced, threats caused by insects and diseases are avoided, extracted volatile ingredients of the plants have very good dispelling effects on insects of the crops, then resin is adopted for mixing, degradation of the resin can play a controlled-release role, and meanwhile, the resin is a very good protecting and storing unit for the active ingredients.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a fertilizer additive for improving crop immunity and a preparation method thereof. Background technique [0002] In nature, there are more than 100,000 known low-molecular-weight secondary metabolites synthesized and released by plants, of which volatile substances account for a large proportion, and most of them have a certain "smell". This kind of substance plays a very important role as a chemical signal of behavior hint between plants and between plants and insects. The control of pests and diseases through chemical pesticides not only damages the environment and wastes resources, but also improves the resistance of crop pests. Pesticides and serious pesticide residue problems affect human health and the management of pests is becoming more and more difficult. [0003] The volatile substances of plants belong to the secondary metabolites of plants. They are ...
