Calcium amino acid composite fertilizer and preparation thereof

Abstract

The invention discloses an amino calcium compound fertilizer and a manufacture method thereof; a finished product is manufactured by mixing raw material, zeolite, with carbamide, monoammonium phosphate and agricultural lemery after the zeolite is crashed; then feeding the mixture into a liquid melt storage slot; adding self-produced compound amino complex compound mixture after melting, fully anduniformly stirring the mixture, using a rotary nozzle pelletizer to pelletize; dropping spherical materials after pelleting in a prilling tower, drying and cooling the spherical materials by the air in the tower, and then carrying out sieving, measuring and packaging. The technique of the invention is simple, the manufacture cost is low and the prepared amino calcium compound fertilizer has the following advantages of: stimulating the plants to grow and improving crop output; upgrading crop quality and increasing the contents of protein, vitamin and sugar; having the effect of pesticide, reducing pesticide amount and reducing pesticide remnant amount; improving soil environment and promoting fertilizer soil productivity; improving and activating the soil; adjusting the vital movements of the plants and enhancing crop resilience such as drought resistance, cold resistance and lodging resistance, etc.; besides, the fertilizing cost is low, the ratio of output to input is high and economic benefit is good.

Description

Amino acid calcium compound fertilizer and preparation method thereof Technical field The invention belongs to the technical field of compound fertilizers, and specifically relates to an amino acid calcium compound fertilizer and a preparation method thereof. Background technique At present, most of our domestically produced compound fertilizers only contain the macronutrient elements nitrogen, phosphorus, and potassium, which are essential for plant growth, and do not contain water-soluble and easily absorbed secondary elements such as calcium, and do not contain trace elements such as iron, zinc, copper, and manganese. , Boron, molybdenum, cobalt, and no agricultural rare earth elements cerium and lanthanum. Although a few compound fertilizers contain minor elements calcium, trace elements (iron, zinc, copper, manganese, boron, molybdenum, cobalt), and agricultural rare earth elements (cerium, lanthanum), most of them exist in the form of inorganic salts. It rarely exists i...

Problems solved by technology

EDTA and citric acid chelating agents have strong chelating ability, but the price is high; although humic acid chelating agents are low in price, they have low concentration, large molecular weight, and poor chelating ability; amino acid chelating agents have good chelating ability and price , but the production of amino acids and their chelates by traditional techniques is time-consuming and labor-intensive

In domestic and foreign research on the effects of trace elements and rare earth elements on crop growth, there are effect tests of the two alone, but the number is small, and there is a lack of effect tests of the two at the same time.
