preparation example Construction

[0046] The preparation method of the biochar used in the following: After cleaning and air-drying a certain amount of corn stalks, put them in a carbonization furnace, pyrolyze them at 500-700° C. for 30 minutes, take them out after cooling, crush and sieve, and prepare biochar powder.

[0047] The following kelp solid extract is a solid extract prepared from kelp by enzymatic hydrolysis, provided by Stanley Agricultural Group Co., Ltd.

Embodiment 1

[0049] A fertilizer synergist, which is composed of the following raw materials in parts by weight: 40 parts of biochar, 1 part of n-butyl thiophosphoric triamide, 1 part of ammonium thiosulfate, 1 part of humic acid, 0.5 parts of polyglutamic acid 0.5 parts of ammonium polyphosphate, 0.5 parts of kelp solid extract, 0.5 parts of chitosan, 0.5 parts of potassium feldspar, 0.5 parts of calcium carbonate, and 4 parts of filler.

[0050] The present embodiment also provides the preparation method of this fertilizer synergist, comprising the following steps:

[0051] 1) granulating the biochar powder;

[0052] 2) Mix n-butyl thiophosphoric triamide, ammonium thiosulfate, humic acid, polyglutamic acid, ammonium polyphosphate and filler according to the proportion, then add granulated biochar, mix and granulate, Make a particle mixture of uniform size;

[0053] 3) The kelp solid extract, chitosan, potassium feldspar, and calcium carbonate are mixed according to the proportion, spr...

Embodiment 2

[0055] A fertilizer synergist, consisting of the following raw materials in parts by weight: 25 parts of biochar, 3 parts of n-butyl thiophosphoric triamide, 3 parts of ammonium thiosulfate, 5 parts of humic acid, 2 parts of polyglutamic acid 2 parts, ammonium polyphosphate 2 parts, kelp solid extract 2 parts, chitosan 2 parts, potassium feldspar 1 part, calcium carbonate 1 part, filler 4 parts.

[0056] The preparation method of the fertilizer synergist of this embodiment is the same as that of Embodiment 1.

Abstract

The invention belongs to the technical field of synergistic fertilizers, and particularly relates to a fertilizer synergist as well as a preparation method and application thereof. The fertilizer synergist comprises the following effective components: biochar, a urease inhibitor, a nitrification inhibitor, humic acid, amino acid, ammonium polyphosphate, a seaweed extract, chitosan, potassium feldspar and calcium carbonate. The fertilizer synergist provided by the invention has strong pertinence and stable synergism, can be applied by being mixed with fertilizers to further improve the fertilizer effect, increase absorption and utilization of nutrients by crops and improve the yield and quality, and is worthy of popularization and application.

Description

technical field [0001] The invention belongs to the technical field of synergistic fertilizers, in particular to a fertilizer synergist and its preparation method and application. Background technique [0002] Chemical fertilizers have played an irreplaceable role in promoting the development of my country's food and agricultural production, but there are still problems such as excessive and blind application of chemical fertilizers, which have brought about increased costs and environmental pollution. Therefore, the development of safe and efficient new fertilizers, the improvement of fertilization methods, and the improvement of fertilizer utilization rate play an important role in promoting the sustainable development of agriculture. Fertilizer synergists are a class of substances that can increase nutrient availability, promote crop nutrient absorption, and improve fertilizer utilization efficiency. In recent years, they have also received more and more attention and use...
