Abstract

The invention belongs to the technical field of fertilizers. The invention discloses a novel fertilizer slow-release long-acting agent. The agent is prepared from the following raw materials: 30% of aurease inhibitor composition, 20% of a nitrification inhibitor composition and 40% of an auxiliary material composition, wherein the urease inhibitor composition comprises thiophosphoric triamide andhydroquinone, the nitrification inhibitor composition comprises thiourea and dicyandiamide, the auxiliary material composition comprises a phosphorus activator humic acid papermaking black material,a plant physiological activator, complex rare earth, modified rare earth and nutrient element adsorbent zeolite powder; the ratio of the thiophosphoric triamide to the hydroquinone is 1: 10; the ratioof the thiourea, dimethyl pyrazole phosphate and the dicyandiamide is 1: 5: 6; the phosphorus activator humic acid papermaking black material, the plant physiological activator, the complex rare earth, the modified rare earth and the nutrient element adsorbent zeolite powder are proportioned according to the ratio of 1: 1: 1: 1. The problems that the fertilizer efficiency is low, and existing market fertilizer slow-release agents are few in variety and high in cost are solved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a novel slow-release long-acting fertilizer for fertilizers. Background technique [0002] Slow-release fertilizers, also known as slow-available fertilizers or control-release fertilizers, contain nutrient-containing compounds that are released slowly in the soil or the nutrient release rate can be controlled to a certain extent for continuous absorption by crops. use. [0003] At present, the existing long-acting fertilizers on the market are as follows: one is coating, that is, coating and fertilizer; Because of many factors such as cost and technique, the agent is not convenient for promotion and use in the market. Contents of the invention [0004] In order to solve the above-mentioned problem that prior art exists, the object of the present invention is to provide a kind of. [0005] The technical scheme adopted in the present invention is: a novel sust...
