Embodiment 1

[0012] Raw material (parts by weight): monoammonium phosphate (containing N: 11%, containing P 2 O 5 : 44%) 10 parts, ordinary calcium (also known as superphosphate containing P 2 O 5 : 16%) 56.9 parts, ammonium sulfate (containing N: 21%) 10 parts, ammonium bicarbonate (containing N: 17%) 15 parts, potassium sulfate 8 parts, appropriate amount of water, diethyl aminoethyl hexanoate (also called caproic acid) Diethylaminoethanol ester, DA-6) 0.04 parts, talc 0.7 parts, carbofuran (2,3-dihydro-2,2-dimethylbenzofuran-7-ylmethyl carbamate) 0.1 part.

[0013] After mixing a proper amount of monoammonium phosphate, general calcium, ammonium sulfate, ammonium bicarbonate, and water (the mixture feels damp when grasped by hands), stack it for 48 hours, then mix it with potassium sulfate and diethyl aminoethyl hexanoate and send it to the manufacturing plant. The granulator is sprayed with water vapor for granulation, and after drying, it is made with a mixed puff powder of talc and carbo...

Embodiment 2

[0015] Raw material (parts by weight): ordinary calcium (including P 2 O 5 : 16%) 1 part, monoammonium phosphate (containing N: 11%, P 2 O 5 : 44%) 50 parts, ammonium sulfate (including N: 21%) 19 parts, ammonium bicarbonate (including N: 17%) 10 parts, appropriate amount of water, potassium sulfate (including K 2 O: 50%) 20 parts, 0.05 parts of diethyl aminoethyl hexanoate, 0.8 parts of talc, and 0.15 parts of carbofuran.

[0016] After mixing a proper amount of calcium, monoammonium phosphate, ammonium sulfate, ammonium bicarbonate, and water (the mixture feels damp when grasped by hand), stack it for 48 hours, and then mix it with potassium sulfate and diethyl aminoethyl hexanoate and send it to the manufacturing plant. The granulator is sprayed with water vapor for granulation, and after drying, it is made with a mixed puff powder of talc and carbofuran (the process is shown in the figure), that is, N: 12%, P 2 O 5 : 24%, K 2 O: 10% seed fertilizer.

Embodiment 3

[0018] Raw material (parts by weight): ordinary calcium (including P 2 O 5 : 16%) 1 part, monoammonium phosphate (containing N: 11%, P 2 O 5 : 44%) 70 parts, ammonium sulfate (including N: 21%) 1 part, ammonium bicarbonate (including N: 17%) 14 parts, appropriate amount of water, potassium sulfate (including K 2 O: 50%) 13.1 parts, diethyl aminoethyl hexanoate 0.04 parts, talc 0.7 parts, carbofuran 0.13 parts.

[0019] After mixing a proper amount of calcium, monoammonium phosphate, ammonium sulfate, ammonium bicarbonate, and water (the mixture feels damp when grasped by hand), stack it for 48 hours, and then mix it with potassium sulfate and diethyl aminoethyl hexanoate and send it to the manufacturing plant. The granulator is sprayed with water vapor for granulation, and after drying, it is made with a mixed puff powder of talc and carbofuran (the process is shown in the figure), that is, N: 12%, P 2 O 5 : 35%, K 2 O: 7% seed fertilizer.

Abstract

This invention discloses a method for preparing functional fertilizer for maize seeds. The functional fertilizer comprises: monoammonium phosphate 10-70 parts, calcium superphosphate 1-60 parts, potassium sulfate 8-20 parts, ammonium sulfate 1-20 parts, ammonium bicarbonate 5-15 parts, diethyl aminoethyl hexanoate 0.04-0.05 part, carbofuran 0.1-0.15 part, and talcum powder 0.7-0.8 part. The method comprises: reacting ammonium bicarbonate, monoammonium phosphate, calcium superphosphate, ammonium sulfate, and free acids to obtain weak acidic fertilizer, mixing with potassium sulfate and diethyl aminoethyl hexanoate, granulating, drying, coating with mixed powder of carbofuran and talcum powder, and packaging. The functional fertilizer can contact maize seeds without any influence on the budding rate. The functional fertilizer can kill pests and promote maize growth.

Description

Technical field [0001] The invention relates to a functional corn seed fertilizer and a preparation method thereof, and belongs to the field of fertilizers. Background technique [0002] The three-leaf period of maize is the transition period from seed nutrition to soil nutrition. The stored nutrients in crop seeds are almost exhausted, and the root system is still very weak. It has a small contact surface with the soil and shows poor fertility absorption. Especially for summer maize, the last crop has absorbed most of the N, P, and K in the soil, and the stubble is tightly connected without being able to apply basal fertilizer, so that the seedling stage maize shows varying degrees of N, P, and K deficiency. It has a great impact on the increase of roots and strong seedlings of corn, which in turn affects the growth of its output. The best way to change this situation is to increase the application of fertilizers. However, there is currently no ternary compound fertilizer that c...
