Fertilizer additive having dual slow-release effect and preparation method thereof

Abstract

The invention discloses a fertilizer additive having a dual slow-release effect and a preparation method thereof; the fertilizer additive is prepared from the following raw materials in parts by weight: acrylic acid, starch, N,N'-methylene bisacrylamide, triadimefon, a urease inhibitor, fly ash, medical stone, itaconic acid, activated carbon, a plant source raw material and a proper amount of water. The invention belongs to the fertilizer additive having the dual slow-release effect, the fertilizer additive is prevented from being mixed with chemical nutrient addition ingredients but is alone used as an addition ingredient and has the advantages that the additive has the slow-release effect, affects fertilizer fast-acting property, and also contains a variety of active adsorption particles; along with decomposition of resin, particles enter soil, and the fertilizer additive has the functions of retaining the fertilizer and absorbing water, and belongs to a long-term effective and protective substance; the fertilizer additive also has the plant volatile ingredients, has aversion effect on pests, and reduces threat of diseases and insect pests; and with use of starch for grafting, the resin is effectively molded.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a fertilizer additive with double slow-release effects 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...
