preparation example Construction

[0037] The present invention also relates to the preparation method of biochar fertilizer as described above, comprising:

[0038] The biochar, attapulgite, sepiolite, dried poultry manure, monoammonium phosphate, calcium magnesium phosphate fertilizer, potassium chloride, urea, methyl cinnamate and dicyandiamide are mixed and granulated to obtain the product.

[0039] According to one aspect of the present invention, the present invention also relates to the application of the above-mentioned biochar fertilizer as a long-acting corn fertilizer.

Embodiment 1

[0042] The present embodiment provides a kind of biochar fertilizer, comprising:

[0043] 50g of biochar, 10g of attapulgite, 50g of sepiolite, 20g of dried poultry manure (cow manure accounts for 60wt%, chicken manure accounts for 40wt%), 5g of monoammonium phosphate, 14g of calcium magnesium phosphate fertilizer, 14g of potassium chloride, and 8g of urea , methyl cinnamate 1.6g and dicyandiamide 0.2g;

[0044] Wherein, the particle diameters of the attapulgite and the sepiolite are both 200 mesh;

[0045] The preparation method of the biochar is as follows: collecting the black liquor of wheat straw pulping by the immonium method of a paper mill, and drying at 80° C. for 24 hours to remove moisture. The dry lignin powder was placed in a cylindrical stainless steel reactor with a lid of 14.5 cm height and 7.5 cm inner diameter, and pyrolyzed in a muffle furnace (2116, Thermo Scientific, America) at 600 °C for 1.5 h. The reactor was then cooled to room temperature in the fur...

Embodiment 2

[0048] The present embodiment provides a kind of biochar fertilizer, comprising:

[0049]70g of biochar, 30g of attapulgite, 30g of sepiolite, 40g of dried poultry manure (cow manure accounts for 70wt%, chicken manure accounts for 30wt%), monoammonium phosphate 3g, calcium magnesium phosphate fertilizer 20g, potassium chloride 6g, urea 12g , methyl cinnamate 2.4g and dicyandiamide 0.3g;

[0050] Wherein, the particle diameters of the attapulgite and the sepiolite are both 160 mesh;

[0051] The preparation method of the biochar is as follows: collecting the black liquor of wheat straw pulping by the immonium method of a paper mill, and drying at 80° C. for 24 hours to remove moisture. The dry lignin powder was placed in a cylindrical stainless steel reactor with a lid of 14.5 cm height and 7.5 cm inner diameter, and pyrolyzed in a muffle furnace (2116, Thermo Scientific, America) at 400 °C for 2.5 h. The reactor was then cooled to room temperature in the furnace.

Abstract

The invention relates to the technical field of agriculture, and particularly, relates to a bio-carbon fertilizer as well as a preparation method and application thereof. The bio-carbon fertilizer isprepared from the following components in parts by weight: 50 to 70 parts of charcoal, 10 to 30 parts of attapulgite, 30 to 50 parts of sepiolite, 20 to 40 parts of dry livestock manure, 3 to 5 partsof monoammonium phosphate, 14 to 20 parts of calcium magnesium phosphate fertilizer, 6 to 14 parts of potassium chloride, 8 to 12 parts of urea, 1 to 3 parts of methyl cinnamate and 0.2 to 0.3 part ofdicyandiamide; the bio-carbon is prepared from dry powder of lignin by high-temperature thermal cracking. The fertilizer is good in fertilizer efficiency and long in duration of the fertilizer efficiency, and can effectively promote crop growth.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a biochar fertilizer and its preparation and application. Background technique [0002] Biochar is a kind of carbon-rich, highly aromatized and highly stable organic matter produced by high-temperature pyrolysis (usually <700°C) of organic raw materials under complete or partial anoxic conditions. Biochar provides comprehensive solutions to global climate change, food crisis and ecological pollution restoration. Biochar can significantly improve the physical and chemical properties of soil. Its porous characteristics and large specific surface area are conducive to the accumulation of water in the soil, increasing the porosity and reducing the bulk density, thus providing a good environment for plant growth. At the same time, biochar is an ideal amendment for acidic soil. The nutrients contained in biochar can be directly input into the soil, and its surface charge and...
